10kV MV Indoor SF6 Load Break Switch, VFL(R)N36-12kV
1. General description
EXFL(R)N36-12kV indoor M.V. AC load break switch is our company according to the international new technology, and according to the relevant standard of power system in China developed medium voltage switchgear,its performance indicators is full compliance with the IEC420,694,129 and the national standard GB3804-2004 3.6kV-40.5kV M.V. AC Load Switch, GB1985-2004 M.V. AC Disconnectors and Earthing Switches, GB/T11022-1999 Switch Equipment and Control Equipment Standard Shared Technical Requirements, is the main switch components of ring network cabinet.
The indoor load break switch is set closing, opening, grounding for the integration of multi-function medium voltage switchgear, in a fully sealed, epoxy resin shell filled with strengthening to 0.05 MPa of SF6 gas. With a minimum of parts to achieve the above three functions, ensuring that the product quality, improve the reliability. Under normal conditions can be safe operation for more than 20 years with maintenance free.
