Separate-phase design, the surface of insulating parts is painted with conductive or semi-conductive material and connected to earth reliably. Phase to phase and phase to earth are isolated so there is no internal arc. The switchgear can run in all service conditions.
Disconnector and earthing switch are vacuum insulated. The product is fully sealed and the protection degree of its primary components reaches IP67.
The integrity of vacuum in the vacuum interrupters can be monitored by means of on-line vacuum monitoring technology.
As it is solid insulated, there is no SF6 in it, more environmentally-friendly.
Modular design, easy and convenient to install and maintain; the faulted panel can be disassembled alone and then replaced, which improves the continuity of power supply.
