35kv High Voltage Switchgear Power Distribution Cabinet Electrical Distribution Panel

Armored open ac metal closed switchgear

1. An overview of the

Armored shifting AC metal closed switchgear (hereinafter referred to as switchgear) is designed and developed by our company, with rated voltage and frequency of 40.5kV and 50(60Hz) respectively. It is mainly used in factories and power systems to receive and distribute electric energy and to control, protect and monitor circuits. Its main feature is that it can match vacuum circuit breaker or SF6 circuit breaker. The cabinet adopts assembly structure to improve the quality and precision of products. Widely used in apply to 6 KV / 6.3 KV / 7.2 KV, 10 KV / 12 KV /

22 KV / 24 KV, 33 KV / 35 KV / 40.5 KV box type transformer power distribution cabinet city network reconstruction, residential area, high-rise buildings, industrial and mining, hotels, shopping malls, airports, docks, highway, railway, oilfield and temporary electricity set inside and outside the workplace.
