Gas - Insulation Metal - enclosed Switchgear / Vacuum Circuit Breaker Switchgear
Overview
The switchgear is a kind of composite apparatus which seals all main circuits in a metal enclosure and take SF6 gas as arc extinguishing and insulation medium. It is suitable for ring network power supply and double radiates power supply in 10kV MV power supply network. It is also used in terminal power supply. Due to the use of ring network power supply increases the reliability of power supply, it is specially used in mineral plants, residence area, schools, parks, and so on for power distribution and controlling. In addition, because of its convenient connection and installation, small volume, it is also used in the substation as high voltage equipment on primary side.
Notes for order
1. Major connection scheme number and single line systematic diagram, layout chart;
2. Secondary circuit schematic diagram, Terminal arrangement diagram (without terminal arrangement diagram, it will be taken by manufacturer's specification);
3. Cable and cable termination’s specification and type should be confirmed when ordering;
4. If the switchgear is used in special environment, the customer should negotiate with the manufacturer when ordering;
5. If spare parts or accessories are in need, the customer should provide its name and quantity.
