GHXGEN Series Eco-Friendly Air-Insulated Non-Motorized Smart Ring Main Unit (RMU))
GHXGEN Series Eco-Friendly Air-Insulated Non-Motorized Smart Ring Main Unit (RMU)The GHXGEN Series Eco-Friendly Non-Motorized Gas Insulated Smart Ring Main Unit (RMU) is a next-generation medium-voltage switchgear designed for sustainable power distribution. Featuring a reliable non-motorized mechanism coupled with smart monitoring features, it delivers safe, cost-effective, and maintenance-free operation for modern grids. Instead of SF₆ gas, it uses high-purity clean air or nitrogen as the insulating medium, significantly reducing environmental impact while maintaining excellent electrical performance.
Developed through nearly ten years of research, testing, and continuous improvement, the GHXGEN series features a fully sealed stainless-steel gas tank, a vacuum interrupter with advanced soft encapsulation technology, and a compact modular design for safe, reliable, and maintenance-free operation.
Available in 12kV and 24kV ratings with 630A and 1250A current options, the GHXGEN series supports flexible OEM/ODM solutions and complies with IEC standards and Indonesia PLN technical requirements.
