In recent years, with the continuous expansion of China's urban power grids and the rapid growth of electricity loads, coupled with the characteristics of long power supply lines and high line losses in rural grids, the original 10kV voltage level distribution has struggled to meet power supply requirements. It has gradually revealed weaknesses such as excessive power supply distance, high line loss rates, and difficulty in meeting voltage quality standards. In contrast, adopting a 20kV voltage level for power supply offers a series of advantages, including increased power supply capacity, ensured voltage quality, reduced power grid energy losses, and savings in grid construction costs. Therefore, adopting the 20kV voltage level for power distribution is an inevitable trend in development and is imperative. The ZW32-24 series outdoor high-voltage vacuum circuit breaker is a three-phase AC 50Hz, rated voltage 24kV outdoor switching device, suitable for switching various types of loads and frequent operation scenarios. It is applicable for the construction and renovation of power equipment in urban grids, rural grids, mining areas, and railways. This product, developed by incorporating advanced foreign technology and based on domestic raw materials and processes, is a 24kV outdoor high-voltage switching device tailored to China's national conditions. Compared to international counterparts, it features compact size, maintenance-free operation, and intelligent capabilities. Additionally, this product does not pollute the surrounding environment and is an eco-friendly, green product.
