Product Overview:GW5A- 40.5KV 72.5KV 126KV Series Disconnector
GW5A series outdoor high-voltage transmission equipment with three-phase AC frequency of 50Hz/60Hz is used to disconnect or connect high-voltage lines under no-load conditions, in order to convert the high-voltage lines, change the operating mode, and implement safe electrical isolation of high-voltage electrical equipment such as busbars and circuit breakers for maintenance.
This product is a double column horizontal V-shaped middle opening type, which can be equipped with grounding switches on one or both sides. The isolation switch and grounding switch with 90 ° transmission adopt CS11 type manual operating mechanism for three pole linkage operation; The isolation switch with 180 ° transmission adopts CJ2 type electric motor operating mechanism or CS14G type manual operating mechanism for three pole linkage operation; The grounding switch adopts CS11 type manual operating mechanism for three pole linkage operation.
