Product Introduction

Product Advantages

High reliability, the entire high-voltage system is in a completely enclosed state, thus not affected by external environmental conditions such as condensation, pollution, high altitude, and other factors.

Low partial discharge, whole machine partial discharge less than 20pC, excellent insulation performance;

Compact design, circuit breaker cabinet width 500mm, load switch cabinet width 450mm, cabinet depth <1m, compact structure, saving installation space.

Equipped with complete "five-prevention" structure, operating mechanism adopts mechanical interlocking method, high safety.

Suitable occasions and regions

Used in power systems such as wind turbine towers, photovoltaics, distribution switching stations, box-type substations, cable branch boxes, etc., for receiving and distributing electric energy, greatly improving the reliability and utilization rate of power supply, effectively saving floor space.
