GW4 series outdoor AC HV disconnector is three-phase AC 50Hz outdoor HV electric equipment used in rated voltage 35KV electric system. It is used for high voltage lines no-load switching and electrical isolation of examined high voltage bus, circuit breakers and other electrical equipments.
GW4-40.5\GW4-40.5D series disconnector is unipolar, and three separate unipoles are connected together by a connecting rod to form a three-pole single conductive arm, linked disconnector. The connecting rod is composed of left hand and right hand screws, so it is easy to adjust the phase synchronization and also can operate on single-phase.
GW4-40.5 series disconnector is composed of base, pillar porcelain insulator and conductive components, each pole has two porcelain insulators on both bearing houses of base, and is connected by a crossover connecting rod to be horizontally revolvable. Conductive knife is made of copper tubes; Its contacts are in middle of the two insulators, and the knife is fixed at the top of insulators.
GW4 Series disconnector are 3-pole outdoor HV a. C electric devices, including 40.5kV, 72.5kV, 126kV and 145 kV disconnectors, which own 3-pole double-horizontal-break construction, consist of installation base, supporting insulator, rotating insulator, moving contact, fixed contact and earthing switch, etc.
