Analysis of Development Status and Trend of Low-voltage Electrical Appliance Industry

In recent years, although China's low-voltage electrical manufacturing industry has made a certain degree of progress, but the loophole in the company's economic scale is the development of the domestic low-voltage electrical industry can not be ignored. China's low-voltage electrical manufacturing companies are mainly concentrated in Beijing, Tianjin, Liaoning, Shanghai, Jiangsu, Zhejiang and Guangdong, and the distribution of enterprises is generally reasonable. There are several problems in the economic scale of enterprises:

(1) The corporate organization is small and scattered and lacks competitive strength and advantages. At present, China's low-voltage electrical enterprises enter the country's large-scale enterprises are few, and SMEs account for more than 90% (the annual sales revenue and total assets of 500 million yuan and above for large-scale enterprises; 50 million yuan and above for the medium-sized Enterprises, the rest are small businesses.

(2) The convergence of regional structures cannot reflect comparative advantages and collaborative benefits. In the 20 years since the 1980s, the number of low-voltage electrical appliances has increased from more than 600 to more than 1,000 today. Due to blind projects and stalls, the phenomenon of regional industry convergence is serious, low economic efficiency, low level of repeated construction, resulting in product backlog, energy, material waste, adverse effects of low economic efficiency.

(3) The technical structure is irrational, and the level of major industrial technology and equipment is low. According to statistics, in the company's main technical equipment, only 1/3 of the technical and economic performance is advanced. The leading products of key enterprises reached only about 18% of the international technological level in the 1990s.

If China's low-voltage electrical industry does not increase investment in research and new product R&D, does not increase research on basic generic technologies and quickly improve the ability of independent innovation of enterprises, it will certainly hinder the sustainable development of China's low-voltage electrical industry and lose its market competitiveness. The final wait for them is undoubtedly "kicked out."

At present, the external environment facing the low-voltage electrical appliance industry is indeed more optimistic. In 2012, when a variety of operating data of the electrician industry encountered “Waterloo”, the good performance of the low-voltage electrical industry has brought a bit of comfort to the industry.

Back in 2011, although the growth rate of electric power and real estate investment declined, the low-voltage electrical appliance industry was driven by a new round of rural power grid reconstruction and the construction of affordable housing, and the overall production and sales of the industry still showed a significant increase over the previous year. According to statistics, in 2011, the total production and sales volume of low-voltage electrical appliances and the sales volume of main products increased by approximately 15% from the same period of 2010, and the production and sales of many outstanding enterprises in the industry grew by more than 30%.

In fact, this trend of rising contrarians is not enough to make domestic low-voltage electrical companies relax their vigilance. Driven by the corresponding interests, well-known foreign electric companies have successively seized the domestic market. Internationally renowned companies such as Schneider, Fuji, Siemens, and ABB have successively landed in China. In addition to segmenting domestic high-end markets, they also implement a “localization” strategy, setting up factories in China with wholly-owned or joint ventures, and occupying a growing market share in the domestic mid-end electrical market, even in the country. The low-end market for electrical appliances. This is undoubtedly a fatal blow to domestic low-voltage electrical appliances "low price advantage", and ultimately can only force companies to survive in the gap between the low-level market.

For some time in the future, China's low-voltage electrical appliance market cake is still very large, domestic companies must always think in times of danger, and constantly improve their own technological innovation and research and development capabilities, master the core competitiveness, and continuously narrow the gap with foreign high-end products in order to be attractive A cup of cake in front of the cake.

The future development of low-voltage electrical products will present the following development trends

Low-voltage electrical products intelligent. In modern power plants and industrial and mining enterprises, electronic computer monitoring systems have been widely adopted, and high-performance and intelligent requirements have been put forward for the corresponding low-voltage circuit breakers, and the products are required to be protected, monitored, tested, self-diagnosed, displayed, etc. Features.

Electronic products. In a modern enterprise, the use of a PC control system instead of a system consisting of electrical-mechanical components has become the mainstream of mechanical electrical control systems. The system requires electrical products with high reliability and high immunity to interference. It also requires the contacts to be able to reliably turn on low voltage and weak currents. The arc at the time of contact disconnection cannot interfere with the normal operation of the electronic circuit.

Product composition and modularization. Combining different functional modules into modular modular appliances according to different requirements is the development direction of today's low-voltage electrical appliances industry. The auxiliary contact assembly, time delay assembly, self-locking assembly, interface assembly, mechanical interlocking assembly and surge voltage assembly are installed on the body of the contactor, which can meet the requirements of different occasions, thereby expanding the scope of application of the product and simplifying the production process. , user-friendly installation, use and maintenance. At the same time, it will further improve product reliability and product quality.
