Live Tank SF6 circuit breaker is an outdoor porcelain pillar structure, equipped with CT35 spring operating structure, and the mechanism and body are arranged in "T" shape. The whole machine is small in size, light in weight, simple in structure, small in operation, and convenient in installation and debugging. Mechanical life 10000 times, suitable for frequent operation;
Compressed gas interrupter, excellent breaking performance, electric life up to 20 times;
Reliable sealing performance, static seal adopts "O" type sealing ring structure, dynamic seal adopts "V" type sealing ring with spring pressure compensation structure. The secondary terminal board of the transformer is produced by pressure injection technology, which has strong anti-aging performance and ensures that the annual gas leakage rate is less than 0.5%.
The installation frame and support are made of the whole steel plate, with high strength standard parts and high mechanical reliability;
The internal or external current transformer metering core is made of microcrystalline alloy with high magnetic permeability, and the accuracy level can reach 0.2 or 0.2s. Each phase of the product can be equipped with 2-4 current transformers.
