outdoor HV disconnecting switch, Insulation switch
General
GW5 series outdoor isolating switch is one of the most commonly used equipment in the power system, the main role is to high voltage isolation in equipment or line maintenance, to ensure the safety of. It should not disconneCT the load current and short-circuit current, should be used in conjunction with the circuit breaker, the first branch circuit breaker in power after the isolation switch, power supply first combined together after the circuit breaker switch.
Genus of double column type V level open type GW5 series outdoor isolating switch, each single comprises a base, a supporting insulator, outlet and the contact part, is composed of two support to 50°,two pillar porcelain insulator on both ends of the angle between the base and the base bearing, vertical. Main electrical parts are installed on the two pillar porcelain insulated bottle top, with the pillar insulated bottle of about 90°rotation.
