I. Overall situation of China's low-voltage electrical industry in 2011
China's low-voltage electrical appliance industry is experiencing unstable economic conditions and the complex and changing international economic environment. Prices of low-voltage electrical main raw materials continue to rise at a high level and continue to rise. Labour costs have risen rapidly. Year of the year. With the joint efforts of numerous entrepreneurs, various corporate management teams and employees of the entire industry, China's low-voltage electrical industry has achieved new developments last year. The output of low-voltage electrical products in the industry will increase by about 10%; the total output value of low-voltage electrical appliances will increase by about 15%. China's low-voltage electrical appliance industry in Changshu, Zhengtai, Shanghai people, Delixi represented a group of outstanding companies continue to be in rapid growth and development.
Among them, the sales growth rate of some outstanding enterprises such as Zhengtai, Suzhou Fattai, Shanghai Liangxin, Wuxi Xinhongtai, Changzhou Xinluokai and Kailong remained at around 30%. However, as raw material costs, labor costs, and financial costs continue to rise, and the price competition for low-voltage electrical products continues, the overall profit growth rate of the low-voltage electrical industry is declining. Many excellent companies, including Changshu Switch Manufacturing (limited) companies, can hardly change this trend. Of course, the overall profit level of these outstanding companies is still at the leading level in the industry. In such a big situation, there are still a few excellent companies that maintain rapid growth in profits. The growth of companies such as Zhengtai, Suzhou Fattai, Shanghai Liangxin, Wuxi Xinhongtai and Changzhou Luokai remains at 20%-30%.
Second, China's low-voltage electrical industry is facing opportunities and challenges
In 2012, the situation faced by China's low-voltage electrical appliance industry still faces both opportunities and challenges. From the overall situation, the opportunities are greater than the challenges.
* Industry development opportunities
1. The sustainable development of China's economy is conducive to the development of low-voltage electrical appliances industry
The average growth rate of China's "12th Five-Year Plan" GDP is 7%. In 2015, China's total GDP will exceed 55 trillion Yuan. At the same time, under the backdrop of the grand development goals set forth in the “Twelfth Five-Year Plan†and the sustained growth of the macro economy, fixed-asset investment, industrial production, and overall consumption, especially the rapid growth of urban population, will inevitably boost power generation and electricity consumption. growth of. Therefore, the future market for low-voltage electrical appliances will continue to expand.
2. The innovation drive and transformation and upgrade proposed in the “Twelfth Five-Year Plan†are conducive to upgrading the low-voltage electrical appliance industry.
The "Twelfth Five-Year Plan" clearly requires strengthening the transformation of economic development mode and promoting technological innovation.
3. China's power industry will continue to promote the development of low-voltage electrical industry
In recent years, China's annual capacity for power generation equipment has surpassed the total installed capacity of power generation equipment in the United Kingdom and Germany. However, according to the analysis of per capita electricity consumption, China is still at a low level. In 2010, China's per capita electricity consumption was quite comparable to that of the United States in the 1950s, Britain in the 1960s, and Japan in the 1970s. Therefore, in the long run, there will not be surplus power generation in our country, but there is still huge room for development.
During the 12th Five-Year Plan period, the electricity consumption of the whole society is expected to grow at an average annual rate of 8.5%, and in 2015 it will reach 6.27 trillion kWh. The total power investment in the country will increase by 68% over the “Eleventh Five-Year Plan†to 5.3 trillion yuan, of which the investment in power distribution equipment will be nearly 1 trillion yuan, and the installed capacity of power generation equipment in the country will increase by an average of 9.34% annually. The 11th Five-Year Plan's new capacity has doubled.
With the continuous increase in power equipment, the market for low-voltage electrical appliances and complete sets of equipment will continue to grow, which is self-evident. The demand for replacement of old products will increase by 15-20% as a decade ago.
4. The comprehensive construction of smart grid will accelerate the transformation and upgrading of low-voltage electrical appliances industry
The period from 2011 to 2020 will be the main period of China's smart grid construction, and the total investment of smart grids is expected to be close to 4 trillion yuan. At present, the smart grid has entered an important stage of comprehensive construction. The intelligent construction of urban and rural distribution networks will be fully opened. Smart grids and smart complete sets of equipment, intelligent power distribution and control systems will usher in a golden period of development. At the same time, it will accelerate the upgrading of low-voltage electrical products in China and re-divided the low-voltage electrical market. This will certainly be a “gospel†for manufacturing companies with third-generation improvements and fourth-generation low-voltage electrical R&D capabilities.
5. The new round of rural power grid transformation will bring new opportunities for low-voltage electrical companies
In January 2011, the country decided to implement a new round of upgrading and upgrading of rural power grids. During the "12th Five-Year Plan" period, the country's rural power grids will generally be transformed. Basically build a new type of rural power grid that is safe, reliable, energy-saving, environmental-friendly, technologically advanced, and standardized.
It is expected that there will be 500 billion yuan in the country's new round of rural power grid reconstruction project that will be more than a decade old. It is expected that this rural network transformation will bring an explosive increase in the low-voltage electrical market. Many experts did not forget that during the Ninth Five-Year Plan period, the low-voltage electrical products in the transformation of rural power grids over-emphasized the price of the products, resulting in a large number of low-grade low-voltage electrical appliances with poor performance and were used in rural power grids. It brings many hidden dangers to the safe and reliable operation of rural power grids. The transformation of rural power grids must emphasize the quality of electrical and equipment products, product performance and product reliability.
6, the new generation of low-voltage electrical appliances will soon be put on the market will inevitably lead the industry transformation and upgrading
China's new generation of low-voltage electrical appliances first emphasizes independent innovation, and completely frees itself from the imitation-based research and development model. To this end, it is proposed that new generation products should have major breakthroughs in the application of new technologies, and there should be major innovations in the structure of new products, and the performance and function of new products should be significantly improved. At the same time, it should be able to fully meet the development requirements of the smart grid distribution system, while emphasizing green, environmental protection and high reliability. Therefore, low-voltage electrical appliance manufacturers that do not have the ability to innovate, product design technology, and manufacturing capabilities and equipment will face phase-out in the industry reshuffle, and have third-generation and fourth-generation middle-to-high-end low-voltage electrical products that have their own innovation capabilities. Enterprises with advanced manufacturing equipment will further differentiate themselves in the market competition, and the low-voltage electrical appliance industry and product concentration may further increase.
7. The new over-current protection technology will gradually attract the attention of power systems and power consumers after the new generation of products are put on the market. It will fundamentally change the selection concept of low voltage circuit breakers
At present, although China's low-voltage distribution systems and low-voltage electrical appliances have selective protection, selective protection is incomplete. A new generation of low-voltage circuit breakers proposes the concept of full-current, full-range selective protection (referred to as fully selective protection). It will completely change the overcurrent selective protection of the existing distribution system, which is limited to the short-circuit current setting range of the circuit breaker. If it exceeds this current, it may lose selective protection. In addition, the existing terminal distribution system does not have a selective protection function because the main switches are current-limiting switches. Therefore, in the strict sense, the current terminal distribution system of buildings, especially the tens of thousands of households, does not have selective protection. A new generation of universal circuit breakers implements Icu=Ics=Icw with a zone interlocking module. A new generation of MCCBs with partial current limiting selective protection with regional interlocking modules and the selective protection of small circuit breakers SMCB was born, creating the necessary conditions for fully selective protection of the distribution system. It will be a major breakthrough in over-current protection technology for low-voltage power distribution systems in China. Has far-reaching economic and social benefits.
8. The new products and marketing promotion of foreign famous low-voltage electrical appliance manufacturers in recent years have, to a certain extent, “motivated†outstanding domestic companies to continuously pay attention to, follow and surpass the products of foreign companies, otherwise they will lose their competitiveness in the market.
* The industry's challenges
1) Obvious shortage of scientific research and new product R&D investment in the low-voltage electrical appliance industry hinders the sustainable development of the low-voltage electrical appliance industry.
Low-voltage electrical products span multiple disciplines and are comprehensive and technology-intensive. With the development of related technologies, related new materials, and new technologies, a new generation of low-voltage electrical appliances will be born, but a large amount of investment is still needed. According to statistics, outstanding foreign companies can achieve total sales of about 7% in the research and R&D investment of low-voltage electrical products. China's average investment in the low-voltage electrical industry is 1-2% of total sales, and excellent companies are about 3%.
Under the background of the continuous development of new technologies and new products for low-voltage electrical appliances and the increasing attention paid to the development of smart grid and safe use of electricity, if the low-voltage electrical industry in China does not increase investment in research and new product R&D, and does not increase research on basic generic technologies, the Improving the ability of independent innovation of enterprises will inevitably hinder the sustainable development of China's low-voltage electrical industry, and lose its market competitiveness.
2) The rising trend of manufacturing costs of low-voltage electrical appliances is irreversible
In China's low-voltage electrical appliances, low-end products are still produced in large quantities. This batch of products is bulky and consumes a large amount of precious metal silver and copper, ferrous metals, plastics and other materials. Many materials are subject to international market prices. Therefore, the situation in which the prices of main raw materials of low-voltage electrical appliances remain high and even continue to rise will hardly change.
In addition, with the shortage of funds, rising financial costs, and the rapid increase in the wages of employees, the increase in personnel costs cannot be reversed. It will surely cause the profit of low-voltage electrical appliances to keep falling. Many companies are already in a state of low profit and loss. At the same time, the company has increased scientific research, and new product R&D and technical investment have brought difficulties.
3) The impact of well-known foreign brands and the addition of domestic monopoly industries have added to the outstanding domestic low-voltage electrical companies
In the construction of smart grids, the State Grid Corporation of China and many design departments are more inclined to foreign famous brands, coupled with the domestic monopoly industry directly involved in the manufacture of low-voltage electrical appliances, so that existing domestic enterprises, including outstanding enterprises, are at a disadvantage in market competition.
4) There are many low-voltage electrical appliance manufacturers, counterfeiting and price competition still exist, making the general low-voltage electrical products have been in a state of low profit. The profits of products such as DW45 universal circuit breakers that had previously played a major role in the development of the low-voltage electrical appliance industry have also dropped significantly.
5) Difficulties brought about by changes in the R&D mode of low-voltage electrical appliances.
The mass production of medium- and low-grade products in the low-voltage electrical appliance industry in China consumes a lot of raw materials, consumes a lot of energy, and also brings high emissions, which is not conducive to the development of a low-carbon economy. Without transformation, it will face the dual constraints of resources and the environment. The third-generation improved products and fourth-generation low-voltage electric appliances that some excellent companies are developing in recent years will meet the requirements of high performance, high reliability, intelligence, and networking, and meet the requirements for miniaturization, low energy consumption, and environmental protection. Low-voltage electrical product design, research and development has shifted from imitation design to independent innovation design.
Third, the "Twelfth Five-Year" China's overall development trend of low-voltage electrical appliances
1, "Twelve Five" China's overall development trend of low-voltage electrical products
(1) Development of individualized products with independent property rights has become the preferred choice for most companies. Each company should determine 2 to 3 levels of products based on the company's positioning to meet different levels of market demand.
(2) Excellent companies are considering and developing a new generation of low-voltage electrical appliances suitable for the characteristics of their own companies. As a low-voltage electrical appliance industry, a new generation of low-voltage electrical appliances should have the following basic conditions.
1) There are major breakthroughs or major innovations in the application of new technologies, new processes, and new materials
2) Major innovation in product structure
3) Product performance and functionality have been greatly improved and expanded
4) There is a major breakthrough in R&D and design methods
5) The product manufacturing process and equipment are greatly improved. For those enterprises that do not have the above-mentioned conditions, they can improve and perfect the company's new generation of products based on the existing third-generation products.
(3) The first batch of four series of new generation products developed by Shanghai Electronics Group and eight outstanding companies in the industry will be gradually introduced to the market from next year. The low-voltage electrical appliance market will be re-divided:
1) First-generation products will be phased out in the "Twelfth Five-Year Plan"
2) Second-generation products will become low-end products in the low-voltage electrical appliance market and gradually exit the market
3) Third-generation products will become the leading product in the low-voltage electrical market
4) The new generation of products will become the high-end products and development direction of the low-voltage electrical market
(4) In order to cooperate with the new generation product market to promote and enhance the market competitiveness of the enterprise, a new generation of cost-effective, compact, low-cost, popular standard products has attracted everyone's attention. The characteristics of such products should meet the following requirements.
1) Appropriately reduce the performance index, to meet the requirements of about 70% of use.
2) The product has complete basic functions and high reliability.
3) Product miniaturization and low cost.
(5) Low-voltage electrical system integration and overall solutions have attracted more and more companies' attention. An enterprise is one step ahead in terms of system integration and overall plan, and it may lead in the market competition step by step. To this end, in-depth studies should be conducted in the following areas.
1) Typical schemes for low-voltage power distribution systems and various types of low-voltage circuit breakers selection principles and performance coordination studies.
2) Research on low-voltage power distribution and control network systems: including network systems, overall system solutions, various types of communicable low-voltage electrical appliances and other supporting components, and their coordination and cooperation.
3) The overall solution of the over-current protection of the distribution system aims to achieve full-range, full-current selective protection in a very short time
4) The overall solution for overvoltage protection of distribution systems (including new energy systems).
5) Overall solutions for starting, controlling and protecting all types of motors
6) The dual power supply system ATSE selects the overall solution
(6) The next-generation product development must have intelligent and networked functions. It can not only be seamlessly connected to various field bus systems, but also directly connected to industrial Ethernet. The intelligent function should be expanded continuously, and the electrical distribution appliance and the control appliance appear to cross each other, namely the integrated intelligence function, in order to meet the need of the smart grid better. Such as smart grid ACB is no longer a single protection of electrical appliances, but will test, inspection, control, security, management and integration of the five major functions of integrated, multi-functional switch electrical equipment.
China's low-voltage electrical appliance industry is experiencing unstable economic conditions and the complex and changing international economic environment. Prices of low-voltage electrical main raw materials continue to rise at a high level and continue to rise. Labour costs have risen rapidly. Year of the year.
