High-voltage isolating switch GW23-252D

outdoorhorizontaldouble-column

GW23(GT9)-252D/2500-50 type double column (horizontal fracture) foldable outdoor AC high voltage isolating switch is suitable for AC frequency 50Hz, rated voltage 220kV system, used for high-voltage lines, circuit breakers and other electrical equipment without It can be electrically isolated under load and can also be used for switching operation. It is a mature product recommended by our company for high-voltage power distribution networks. It analyzes the defects of the current isolation switch conductive circuit overheating, operating mechanism failure, and severe corrosion of metal materials. After major improvements, it has been successfully developed. The product has many advantages such as beautiful appearance, simple structure, corrosion resistance, good seismic performance, safe and reliable electrical and mechanical performance. • Advanced friction contact • Good conductivity • Guaranteed low loop resistance • Each contact is equipped with independent spring • The spring does not carry current and has a long life • The two states of opening and closing can be self-locked and maintained, effectively preventing the dynamic and static contacts from being separated by the influence of wind and electric power; • The transmission link adopts oil-free bearing and copper alloy bushing, which has self-lubricating ability, which reduces the rust and jam of the rotating link； • Use anti-rust aluminum and stainless steel materials to avoid surface corrosion；
