Product Description
General
SF6 gas is internationally recognized as one of the six greenhouse gases and from environmental protection perspective, there should be little or no SF6 gas used in electrical equipments. Our new generation of solid-insulated RMU uses resin as insulating material instead of SF6, therefore it is very eco-friendly.
