12kV ~ 36kV 2500A 31.5kA MV C-GIS SF6 Gas Insulated Metal-clad Compact Switchgear (GIS)
Product Description:
The gas insulated switchgear designed for installation in transformer substation, industrial plants, and infrastructure & complies the most stringent requirement of
Safety in operation
Staff safety
Operation reliability
Smaller footprints
Reduced maintenance work
This switchgear conforms to IEC 62271-200 and all primary components employed therein are in accordance with the relevant standards.
It is designed to accommodate high performance vacuum circuitbreaker (VCB) which has been designed and tested in accordance with IEC62271-100.
The switchgear panels are suitable for the assembly of single &double busbar systems for indoor installation.
Features:
1. The introduction of advanced technology in Japan, Toshiba Co., Ltd. to develop products.
2. Good insulation performance, small size, filled with SF6 gas as insulation medium.
3. The reliability of the breaking performance, the vacuum circuit breaker for arc extinction,
the life of spring operating mechanism is long.
4. High reliability, the sealed body, and performance that is not affected by the outside world.
5. Safe structure design, all kinds of independent pressure release device,
which can be guaranteed from the internal failure.
6. “five-prevention” equipment is reliable, and with mechanical and electrical interlock.
7. The cabinets is connected by external solid insulated busbar, it’s easy for installation.
8. Cable room has enough space for installation.
