완전 절연형 금속 밀폐형 가스 충전 링 메인 스위치기어

HXGN□-12
HXGN □ -12 fully insulated metal enclosed gas filled ring network switchgear is often called gas filled ring network cabinet. It is a sealed gas box filled with SF6 or dry gas slightly higher than atmospheric pressure, which can effectively prevent pollution, moisture, external substances and other harmful effects, improve the reliability of insulation, and have good anti-aging and anti-corrosion performance. Connected to the outside world through sleeves and cable terminals, it can be reliably used under harsh conditions.

Product Advantages
High voltage components are fully sealed, not affected by external environmental conditions, with good anti-aging and anti-corrosion performance, and strong environmental adaptability.
Low inflation pressure and good air tightness.
One time equipment maintenance free, reducing maintenance work to a small extent and lowering operation and maintenance costs.
Compact structure, saving space.
Modular design, easy on-site installation.
Reliable safety assurance, fully insulated high-voltage components, and shell that can be safely contacted, providing maximum safety protection.
Application Scenarios
This product is suitable for distribution systems with three-phase AC 50Hz and rated voltage of 12kV, especially for receiving and distributing electrical energy in new energy box transformers such as photovoltaic and wind power, small secondary distribution stations, switch stations, industrial and mining enterprises, urban residential areas, airports, railways, tunnels, and high-rise buildings.
