12kV SF6 Insulated Ring Main Unit
GLX24 series SF6 Ring Main Unit is an estensible, SF6 insulated siwtchgear, with rated voltage of 12&24kV. All its HV live parts are contained in an air-tight gas tank, which is made from stainless steel of 3mm. The whole switching assebly is SF6 insulated, and free from any external influence, ensuring it great reliability of service and maintenance free. By plug-in type busbar extension, GLX24 series RMU can be of free combination and full modularization. The busbar extension has passed type test for power and thermal stalility, and is fully insulated and shielded, exhibiting high reliability and safety.
GLX24 series Ring Main Unit is suitable for all MV network up to 24KV, all compact power stations, power distribution substations in all important industries, such as petrol-chemical industry, metallurgical and mining industries, and all transformer substations and wing power system.
