Product Description

The design of GNA series solid insulated Ring Main Unit isbased on mature and reliable vaccum arcing room and high stable and reliable APG technology. No need maintenance(operating over 10thousand times) and SF6 air that greatly reduce the cost of full cycle.
All H.V.electric components adopt single phase insulated design.The special modulated materials provide excellent insulation performance and radiating properties.And the insulation structure with the special design can effectively optimize the electric field distribution so that greatly reduce the risk of internal arcing.
The electric components shall be positioned in enclosed and dry cabinet to protect the whole system from the environment. The usage of vaccum arcing room and solid insulated ensure completely green of GNA solid insulated Ring Main Unit.
The compact design and top busbar extended for the GNA RMU ensure the easy installation; Front cable room achieve the cable bottom in and bottom out connections, Rear cable room can achieve the cable top in and top out connections. So the GNA solid insulated RMU save the land resources and cab be.
