Brief Introduction
XGN20-12L/630-25 and XGN20-12RL/125-31.5 indoor SF6 ring main unit adopts the SF6 load switch as its main switch and the whole cabinet is air insulation. Meanwhile, the switchgear adopts sensing technique and updated protection relay components, this kind of design has reached the international advanced level. It is mostly used to control and protect the circuit, of which rated frequency is 50 or 60Hz and rated voltage is 12kV. And it is especially suitable for being used in the power system of the small secondary distribution substation, box-type substation, mine enterprise, urban residential area, airport, hospital, railway, tunnel and high building. We can provide different technical scheme according to the requirements of clients.
The ring main unit consists of bus-bar compartment, CB compartment, cable compartment, operating device, interlock mechanism, low-voltage control room and measure loop. The chambers are separated by steel plate, which can prevent the failure to affect the other chambers.
