Visual shape Industrial beauty

Electric enclosures-though industrial products, need to meet human’s aesthetic needs. In the R&D of Aikko low-voltage switchgears, Murge’s artisans pay close attention to industrial design from details, interpreting beauty from product modelling to operation interfaces, from color matching to environment integration, and from industrial steadiness to atmosphere creation.

The FMG is a SF6 gas insulated switch disconnector for medium voltage switchgear

within secondary distribution networks, rating up to 36kV. It features compact size

and the lightweight construction. The epoxy resin enclosure is tightly sealed and filled

with SF6 gas as insulation and arc-quenching medium, which can provide good

insulation and resistance to moisture and pollution area, realizing virtually free

maintenance.
