Fully insulated, fully enclosed, maintenance-free vacuum RMU — epoxy-cast live parts and solid insulated busbars, ideal for harsh environments from high altitude to heavy pollution.
All high-voltage live parts of the HP-SIS-12 are cast in epoxy resin of excellent insulating performance, integrating the vacuum interrupter, main conductive circuit and insulating supports into one solid body; functional units are linked by fully insulated solid busbars. The switchgear is therefore immune to external environment, ensuring equipment reliability and operator safety.
Simple structure, flexible operation, reliable interlocking and easy installation for 50 Hz / 12 kV systems. Widely used in industrial and civil cable ring networks and terminal distribution: urban residential supply, small substations, switching stations, cable branch boxes, box substations, factories, malls, airports, metros, wind farms, hospitals, stadiums, railways and tunnels. Full insulation, sealing and shielding make it especially suitable for high-altitude, hot-humid, severe-cold and heavily polluted areas.
