(1) Domestic high voltage switchgear has been fully oil-free, and product upgrades represented by vacuum switches and SF6 circuit breakers have been realized.

Ningbo Tianan (Group) Co. Ltd is a professional China Transformer Manufacturers and China Transformer suppliers. Our factory specializes in manufacturing of Mobile Substation, Circuit Breaker, Cable Branch Box. The transformer is widely used in power transmission and distribution system, hotel, rest......

There are six main types of high-voltage load switches.

After the high-voltage switchgear is closed, check whether the closing fuse is normal. If it is replaced, check whether the capacity meets the requirements.

GW1 outdoor AC high-voltage isolating switch is suitable for installation on outdoor high-voltage power distribution equipment lines for cutting off lines and converting lines when there is voltage and no load.

With the development of the cable distribution network, when the independent load distribution of small capacity is concentrated, the cable branch box can be used to connect the cable multi-branch, because the branch box cannot directly operate on each channel.
