Low-voltage electrical appliances are undergoing a significant transformation toward intelligence. In the fast-paced development of China's low-voltage electrical industry, two key areas require attention: product quality assurance and the intelligent upgrade of electrical products. Companies like Zhengtai and Delixi have set excellent examples in this regard, according to Chen Junyu, the Secretary General of the Zhejiang Electric Industry Association.
User needs remain at the core of product development. In 2012, the total profit of China’s low-voltage electrical industry reached approximately 4.4 billion yuan, marking a 7.32% year-on-year increase. Meanwhile, the total import and export volume reached 5.509 billion U.S. dollars, up by 5.33% compared to the previous year.
Modern power companies increasingly rely on electronic monitoring systems. They demand high-performance, intelligent low-voltage circuit breakers that offer features such as protection, monitoring, testing, self-diagnosis, and display. As a result, the evolution of low-voltage electrical products must align with the broader trends in manufacturing. The move toward system-level intelligence is becoming a major industry trend, with technology demands expanding into smart grids, electric vehicles, and micro-grids.
In practice, companies focus on solving real-world problems to ensure that their products are not only innovative but also practical and widely adopted. For example, Zhengtai Electric Appliances, a leading supplier of smart electrical solutions, emphasizes system-level intelligence rather than just component-level upgrades. When designing new products, the company takes into account the real needs of users across various sectors, including architectural design institutes, power utilities, metallurgy, chemical engineering, and oil fields.
One such case involved an architectural design institute requesting an earth leakage circuit breaker that only triggers an alarm without cutting off power, to avoid disruptions during emergency situations like firefighting. Zhengtai responded by developing a specialized product that met this specific need.
This highlights how user feedback plays a crucial role in shaping product development. Companies gather customer insights through service centers and after-sales support, enabling them to better understand actual user requirements and refine their product positioning in terms of functionality, pricing, and service.
Upgrading low-voltage electrical products has become a pressing necessity. After over half a century of growth, China's low-voltage electrical industry has built a relatively complete industrial system, with an output value of around 20 billion yuan and more than 2,000 manufacturers employing over 400,000 people. However, the market is highly competitive, especially among SMEs and low-end products.
While the domestic market is dominated by mid-to-low-end products, high-end offerings still lag behind foreign counterparts in many areas. According to Chen Junxi, the first and second generations of low-voltage devices were bulky, energy inefficient, and had low profitability. Third-generation models often failed to meet real-world demands, such as delayed overcurrent protection and lack of selective protection in distribution systems.
To address these shortcomings, the development of a new generation of intelligent, modular, and communicative low-voltage electrical products has become a priority. These products aim to meet evolving market needs, technological advancements, and industry standard trends.
Personalized and distinctive products with independent intellectual property rights are now the preferred choice for most companies. Homogeneous products, on the other hand, lead to price wars and declining profits.
The industry is entering a phase of rapid growth. Despite rising raw material and labor costs in 2012, the sector achieved a 10% increase in output and a 15% rise in total value. Industry experts predict that the total output value could reach 40 billion yuan within the next four years.
With the expansion of smart grid projects and the push for renewable energy, the low-voltage electrical market is experiencing a period of rapid growth. Intelligent low-voltage products tailored for the end-user market represent both a great opportunity and a challenge.
As urbanization accelerates, the intelligent construction of power distribution networks will gain momentum, creating a golden era for smart grids, integrated equipment, and intelligent control systems. At the same time, the development of energy-efficient, resource-saving, and high-performance low-voltage products is expected to drive further market growth.
New energy developments are also fueling the intelligent transformation of the industry. Low-voltage electrical products are now expanding into photovoltaic inverters, new energy control systems, distributed energy, energy storage, and DC switchgear. These applications offer comprehensive solutions and represent a promising new economic growth area for the industry.
Diesel generation welding machine, also known as engine welding machine, is a machine integrating the engine and the welding machine, the generator directly drives the welding machine to work by rotating the current, generally there are gasoline power, diesel and diesel power, the most commonly used, with a small power auxiliary power supply, can drive lighting and other low-power equipment. Working principle: firstly, the Diesel Engine drives the generator, and the electricity generated is used to provide AC power for the welding machine, and then the internal rectifier bridge is rectified into direct current, and finally the output is used as the welding power supply.
