The LDS-12 630A Gas-filled Ring Main Unit (RMU) is a high voltage switchgear solution designed for reliable medium voltage power distribution up to 12kV. Using SF6 gas as the insulating and arc-quenching medium, it ensures compact size, maintenance-free operation, and superior safety. Rated at 630A, this RMU is ideal for secondary distribution networks in commercial buildings, industrial plants, and utility substations. It comes with integrated load break switches, earthing switches, and optional protection devices. The sealed stainless steel tank guarantees gas integrity for over 20 years. Complying with IEC standards, the LDS-12 offers versatile configurations including A, B, and C types for various circuit arrangements, and supports remote monitoring and control for smart grid integration. Its robust construction meets IP67 protection rating, allowing outdoor installation without additional housing.
