SF6 Load switch
Products Description
Function
It is used for medium-voltage distribution (12-40.5kV), capable of breaking normal current but not short-circuit current (a fuse is required).
Advantage
It has strong insulation (2-3 times that of air), fast arc extinguishing, small equipment size and long service life.
Application
Ring main units (RMUs), wind power/photovoltaic distribution, compact substations.
Features
Three-position (closing - opening - grounding), airtight design, maintenance-free.
Attention
It is necessary to prevent gas leakage. When retiring, SF6 needs to be recovered (due to the strong greenhouse effect).
