Medium Voltage Switchgear
Indoor metal-clad withdrawable switchgear for primary distribution and ring main units for secondary distribution — covering 12 / 40.5 kV primary and secondary networks to IEC 62271-200.
Medium Voltage Metal-clad Switchgear (KYN28 / KYN61)
Indoor metal-clad withdrawable switchgear for primary distribution — the KYN28 mid-mounted withdrawable-truck design in 12 kV (up to 4000 A), plus the 40.5 kV floor-rolling KYN61 for 35 kV main substations. Four / five-compartment metal segregation with five-prevention interlocks.
Ring Main Units (RMU)
12 kV ring main units for indoor ring-main and terminal distribution, offered in three SF6-free / sealed insulation routes — eco-gas SF6-free (HLXGN), SF₆ fully-sealed C-GIS (HLC) and solid-insulated SF6-free (SLG). Three-position main switch, modular functional units, and optional smart integrated (一二次融合) versions with built-in DTU.
