Mv hxgn-12/630-20 sf6 insulated compact metal-enclosed rmu - modularization design
a mv hxgn-12/630-20 sf6 insulated compact metal-enclosed rmu.
mv hxgn-12/630-20 sf6 insulated compact metal-enclosed rmu is widely used because of reliable performance, excellent durability and maintenance free.
mv hxgn-12/630-20 sf6 insulated compact metal-enclosed rmu is designed of modularization. it not only meets the requirements of end-users and network node, but it also can satisfy the needs of various distribution switching stations, box transformer substations and cable branch boxes. it features compact structure, reliable performance, excellent durability and maintenance free. mv hxgn-12/630-20 sf6 insulated compact metal-enclosed rmu contains a 304 stainless steel box, and all primary electriferous parts and switches can be included in the box, so it is a complete closed system. the protection degree is ip67.
