HV SF6 live tank circuit breaker outdoor40.5KV

General:

Reliable sealing performance, using imported sealant gasket, static seal using "O" type sealing ring structure, dynamic seal using "V" type sealing ring with spring pressure compensation structure. The secondary terminal board of the transformer is produced by the imported mold using the pressure injection process, which has strong anti-aging performance and ensures that the annual gas leakage rate is less than 1%.The whole product adopts stainless steel structure. Fasteners, panels and shells are made of stainless steel, and the internal bracket is hot-dip galvanized, which will never rust.The inner transformer metering grade iron 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.
