JPU1-12 Medium Voltage SF6 ring main unit (SF6 RMU, Abbreviation), with the character of excellence reliability and maintenance free, is suitable for AC 3.6 to 12kV power distribution system with configuration either ring or radiant. Its all live part including LBS, CB, ES and primary busbar are sealed in the tank made of stainless steel and the elbow-shape cable connectors are adopted for the incoming or out-going, that leads to the RMU has less influence from service condition therefore it is suitable for using in the bad ambient condition and relatively restricted space. Its service life is more than 20 years.
JPU1-12 is compliance with IEC 694, IEC 60265-1/FDIS, IEC 62271-100, IEC 62271-102, IEC 298 & IEC 420.
