10kV SF6 Ring Main Units: Structure, Faults & Cable Termination Quality

1. Introduction to 10kV SF6 Ring Main Units (RMUs) A 10kV SF6 ring main unit typically consists of three main parts: the gas compartment (tank), the operating mechanism compartment, and the cable connection compartment. The gas compartment is the core component of the RMU. It is filled with SF6 gas
