Product details
Overview of ZW32-24 (G) series outdoor high-voltage vacuum circuit breaker:
ZW32-24 (G) series outdoor high-voltage vacuum circuit breaker (hereinafter referred to as the circuit breaker) is a three-phase AC 50Hz outdoor switchgear with a rated voltage of 24kV. It is suitable for opening and closing various types of load currents and frequent operating situations, and is suitable for the construction and renovation of power equipment in urban, rural, mining, and railway networks.
This product is a 24kV outdoor high-voltage switchgear suitable for China's national conditions, developed on the basis of absorbing foreign technology and relying on domestic raw materials and processes. Compared with similar products, it has the characteristics of miniaturization, maintenance free, and intelligence. At the same time, this product is pollution-free to the surrounding environment and is a green and environmentally friendly product.
In recent years, with the continuous expansion of China's urban power grid and the rapid growth of electricity load, and in response to the long and high line loss characteristics of rural power grid supply lines, the original 10kV voltage level distribution has gradually exposed its weaknesses such as excessive power supply distance, high line loss rate, and difficulty in meeting voltage quality requirements. Adopting 24kV voltage level power supply has a series of advantages such as increasing power supply capacity, ensuring voltage quality, reducing power grid energy loss, and saving construction costs of the power grid. Therefore, adopting a 24kV voltage distribution level for power supply is an inevitable trend in development and is imperative.
The circuit breaker complies with technical standards such as GB 1984-2003 "High Voltage AC Circuit Breakers", DL/T402-2007 "Technical Conditions for Ordering High Voltage AC Circuit Breakers", and DL/T403-200012kV~40.5kV High Voltage Vacuum Circuit Breakers ".
