Description

GW23 252 KV Double Column Outdoor AC HV Disconnector / Disconnect Switch​

General overview

GW23 (GT9) 252D/2500-50 Type Double Column Outdoor AC HV Disconnector is developed on the basis of aiming at existing defects about disconnector conducting loop overheating, operating mechanism failure, metal material corrosion serious, and then making great improvement.

Advantages

The product has advantages of beautiful appearance, simple structure, high performance of corrosion resistant and antiseismic, safe and reliable electric and mechanical property.

It is the matured product that our company recommends to HV electricity distribution network, and it’s also an upgrade product of disconnector. It is suitable for system with 50Hz AC frequency and 110kV rated voltage. It can be used in electricity isolation when HV line, circuit breaker and other electrical equipments are no-load.
