ZF12 -72.5/126/145 (L) GIS    Gas Insulated Switchgear

 

 

 

Brief Description

 

1.Gas Insulated Switchgear (GIS) is 3-phase AC high voltage switchgear which is used for the control, measurement, protection and switching of transmission lines. Since 1984, more than 5000 bays have been in service, some exported to Thailand, Equatorial Guinea and other countries.

 

2.ZF12 -72.5/126/145 (L) GIS contains major substation equipments, such as circuit breaker, disconnector, earthing switch, voltage transformer, current transformer and surge arrester. All components are three-phase in one closure. The GIS can be connected with incoming and outgoing line of bushing or cable, or directly with the transformer under the different connection requirements.

 

ZF12 -72.5/126/145 (L) GIS    Gas Insulated Switchgear

Main Features

 

1. The mechanism is oil/gas free, simple construction, easy maintenance and reliable operation.

 

2. The enclosure is made of aluminum alloy to ensure light weight, low temperature-rise and strong anti-corrosion..

 

3. Double sealing systems are adopted to guarantee high reliability in gas tightness and the annual gas leakage rate is leaa than 0.5%.

 

4. Excellent insulating, conducting and current carrying performances.
