Product Description

Description

GW4-126D double-column horizontal outdoor AC high-voltage disconnector is suitable for power systems with an AC frequency of 50Hz and a rated voltage of 110kV. It is used for switching high-voltage lines under no-load conditions, as well as for electrically isolating electrical equipment such as high-voltage busbars and circuit breakers under maintenance from energized high-voltage lines, providing a visible insulation distance that meets the requirements for the equipment under maintenance and maintenance personnel.

1. Double-column horizontal rotary structure;
2. Simple structure, easy debugging, beautiful appearance;
3. The isolating switch can be used in single pole, or in three-pole linkage through interphase connecting rod;
4. It has two operation modes: electric and manual;
5. It has mechanical and electrical double interlocking;
6. Most parts are made of aluminum alloy, and special anti-corrosion treatment is adopted, with strong outdoor corrosion resistance;
7. The conductive contact parts are silver-plated, and the silver-plated surface is dipped in antioxidant to prevent the switch from oxidation.

GW4 Type serial High Voltage Outdoor isolator /Disconnector /disconnecting switches comply with requirements in GB1985-2004 High-voltage Allemating Disconnecting Switches and Earthing Switches,IEC62271-102:2002AC Disconnecting Switches and Earthing Switches ,and IEC60694:1996 Common Clause for High voltage Switchgear and Control Devices.
