The GTXGN-12 Solid Insulated Ring Main Unit (RMU) is an environmentally friendly, fully sealed power distribution cabinet designed for medium-voltage electrical networks. This innovative RMU eliminates SF6 gas, ensuring a sustainable, maintenance-free solution for substations, industrial sites, and high-rise buildings.
With its advanced solid insulation technology, the GTXGN-12 guarantees safe and reliable operation even in harsh environmental conditions. Featuring a visible isolation cutout, pressure relief design, and enhanced arc-extinguishing capabilities, this power distribution unit ensures superior performance and longevity.
Key Features
- Visible Isolation Cutout – The front panel includes observation windows for clear visibility of switch positions (open, closed, and grounded), enhancing safety and simplifying maintenance.
- Pressure Relief Design – Equipped with an internal arc pressure relief valve to safely direct harmful gases in the event of an arc fault, ensuring operator safety.
- Eco-Friendly Solution – Free from SF6 gas, this unit reduces environmental impact while optimizing energy efficiency with minimal connection points.
- Enhanced Arc Extinguishing – Uses copper-chromium contact materials and advanced magnetic field technology for improved short-circuit breaking capacity and extended lifespan.
- Modular and Scalable – Available in multiple configurations, including V (circuit breaker), C (load switch), and F (combined components), allowing flexible expansion for future requirements.
