Gas Insulated Ring Main Unit
RM6 is a gas-insulated switchboard (RMU) designed under IEC
62271-1 standard, combining all medium voltage functions to enable the connection, supply, and protection of transformers for an open ring or radial network. RM6 can also meet medium voltage secondary distribution needs in more complex network configurations where renewable energy supply sources are involved.
