Solid insulation ring grid cabinet is an intelligent environmental protection ring grid cabinet that appears in the domestic and foreign markets in recent years. It is a solid insulation power supply equipment designed and manufactured by automatic pressure gel technology and casting the array switch and related live parts with epoxy resin as a whole. This power supply equipment does not discharge any toxic substances, fully meet the environmental requirements. This solid insulation power supply device shortens the interphase and ground safety insulation distance from 125mm of air insulation to 6-8mm, greatly reducing the volume of switch cabinet. As all connection parts inside the switch are poured with epoxy resin, the strength of connection parts is much stronger than that of gas switch cabinet. Like SF6 inflatable cabinet, this switchgear can be used in harsh environments and is truly maintenation-free.
