GW27 series high voltage AC disconnector is designed and manufactured by our company recent years with super high voltage, big current and high move-heating stability. GW27 had passed all type tests of KEMA International Electric Laboratory in Holland and China National High Voltage Quality Monitoring and Checking Center. The rated voltage of GW27 series can be ranged from 110KV to 1100KV, the rated current from 2000A to 4000A. GW27 series disconnector is three poles and horizontal rotation break. GW27 series, designed and manufactured, is based on the strongpoint of other products. The character has great improved especially in anticorrosion. It can be compared with same products of other manufactures.

In the main blade system, the conduct rod has a double ways for moving, one is level moving and the other is rotate in transverse. It can greatly reduce the operating force in the process of opening and closing. The earthing switch has simple structure and reliable function. GW27 series has some good advance such as newly structure, rational design, excellent performance and reliable operation and high parameters and so on. This series had gained letter of patent of china state. ZCW1 is the different assembled of GW27. GW27 series disconnector is used to switch power circuit and isolate the repaired equipment.

The operating mode:

To 252KV disconnector, main blade and earth blade are three phase mechanical gang operation.

To 363KV disconnector, main blade and earth blade can be three phase mechanical gang operation or one phase mechanical operation.

To 550KV and above disconnector, main blade and earth blade are one phase mechanical operation.

The disconnector of one phase mechanical operation is able to operate with three phase electric gang.
