Development of low-voltage electrical industry

Overview

Low-voltage electrical appliances are essential components used in electrical systems to manually or automatically control the flow of electricity. These devices can switch, protect, detect, and regulate circuits or non-electrical objects based on external signals. They are categorized into high-voltage and low-voltage control devices, with the dividing line being AC 1200V and DC 1500V. Typically, low-voltage electrical appliances are split into two main types: distribution and control devices. As fundamental elements in electrical equipment, they play a critical role in various sectors such as industry, agriculture, transportation, defense, and daily life. Since most applications rely on low-voltage power supply, the quality of these components directly impacts the reliability and efficiency of the entire system.

Industry Development

The low-voltage electrical industry in China has seen significant growth over the past few years, with both private and foreign-owned enterprises playing key roles. Private companies from Wenzhou, such as Chint, Delixi, and Tianzheng, have traditionally focused on the lower end of the market. On the other hand, state-owned enterprises like Changshu Switch Manufacturing and Shanghai Electric Appliance Factory have been gradually shifting toward higher-end products through increased R&D efforts. Foreign-invested enterprises, often joint ventures or wholly-owned subsidiaries of international brands, bring advanced technology and production methods into the Chinese market. While they focus on high-end segments, they also increasingly target the mid-to-low-end markets. Companies like ABB, Siemens, and Schneider Electric have fully entered the Chinese market, competing across all levels. With globalization, the integration between domestic and foreign firms is becoming inevitable. This includes domestic companies expanding their high-end product presence abroad and foreign firms entering the local mid-to-low-end markets. Although foreign firms have strong R&D and management capabilities, many domestic companies, especially private ones, excel in flexibility and sales networks. However, their scale and product consistency still need improvement. Government support for industrial clusters and value chain expansion will be crucial in driving the industry toward specialization, precision, and innovation.

Forecast

With the ambitious goals of the 12th Five-Year Plan and sustained economic growth, factors like fixed asset investment, industrial output, and urban population expansion will significantly boost electricity demand. This trend is expected to drive continued market growth for low-voltage electrical products. Between 2011 and 2020, China's smart grid construction became a major focus, with an estimated investment of nearly 4 trillion yuan. As the smart grid enters its full-scale development phase, intelligent distribution and control systems are set to experience a golden era. This transformation will accelerate the modernization of low-voltage electrical products and reshape the market landscape. For manufacturers equipped with third- and fourth-generation technologies, this represents a major opportunity for growth and innovation.
