GW1–12 High Voltage 36kv 630A Porcelain Type Disconnector/Isolation with Earth Switch

(GW1-12 series outdoor high voltage AC disconnector (hereinafter referred to as "disconnector") It is applicable to the device on the outdoor high-voltage distribution equipment line for the replacement of 10kV line under voltage and no load, and for the electrical isolation of the overhauled high-voltage bus, circuit breaker and other electrical equipment from the live high-voltage line. It can also be used to close a small
capacitive current and inductive current. The Isolation switch (disconnector) is a double column vertical opening type, equipped with a manual or electric mechanism, which can realize three-phase linkage. The Isolation switch meets the technical standards of high voltage AC disconnectors and earthing switches (GB/T 1985-2014) and high voltage AC disconnectors and earthing switches (DL/T 486-2010)
