Cable service of a Ring Main Unit (RMU) involves the installation, connection, testing, and maintenance of power cables linked to the RMU, which is used for medium-voltage power distribution. The service includes terminating incoming and outgoing cables, ensuring proper insulation, and conducting tests like insulation resistance and HiPot to verify the integrity of the connections. Technicians also perform cable jointing and earthing to enhance safety and reliability. Regular maintenance ensures fault-free operation, reduces the risk of outages, and extends the lifespan of both the RMU and connected cables. This service is essential for ensuring stable and efficient power distribution.
