Description
11kV disconnector switch is a switching device, when it is in the separate position, there is an insulation distance and an obvious disconnection mark between the contacts in accordance with specified requirements; in the combined position, it can carry the current under normal loop conditions and under abnormal conditions (such as short circuit) within a specified time.
Product Feature
The GW9 outdoor high-voltage isolating switch has a single-phase structure. Each phase is composed of a chassis, a pillar insulator, a blade, and a contact. There are screws on the side of the blade to adjust the contact pressure and a spring for compression. The upper end is equipped with a fixed pull buckle and a self-locking device connected to it, which is used for opening and closing of the insulated hook rod. It has the advantages of large contact area, low contact resistance, good electrical conductivity, and high mechanical strength.

Packing
Normal packing will be carton+ pallet. Pallets securing your primary packaging (and your product) in a stack to facilitate movement and storage, it provide additional protection. Special packaging arrangements are available upon user request.

Application
The isolating switch is mainly used to isolate the parts that require power outage and the live parts in the high-voltage power distribution device. It is widely used in various power systems, including the following scenarios: Substation scenario: In the substation scenario, the isolating switch is mainly used to cut off various connections between power stations and isolation circuits within substations. Line connection scenario: In the power line connection scenario, an isolation switch can be used to isolate the faulty part or the maintenance part to ensure the normal operation of the entire power system.
