The isolated gas distribution unit (RG-17.5kV SF6 RMU) is an innovative and reliable solution for electrical power distribution. It relies on a patented rotary load switch and a vacuum circuit breaker, ensuring high performance and complete safety.
All primary live parts are hermetically sealed inside a stainless steel tank filled with SF6 gas, completely isolating them from the external environment.
This design makes maintenance unnecessary, thereby enhancing the reliability of the power grid and improving safety levels.

A Ring Main Unit (RMU) is compact medium-voltage switchgear used in electrical distribution networks. It controls, protects, and isolates sections of the network, helping utilities maintain reliable power distribution while minimizing the impact of faults.
The main purpose of a Ring Main Unit is to provide safe switching, protection, and isolation within a medium-voltage distribution network. It allows operators to isolate a faulty section while maintaining power supply to other parts of the network whenever the system configuration permits.
Yes. An outdoor Ring Main Unit is designed with an enclosure suitable for external environmental conditions. Factors such as ingress protection, ambient temperature, humidity, dust, corrosion resistance, and installation location must be considered when selecting the equipment.
The selection should consider the network voltage, rated current, short-circuit rating, number of ways, protection method, indoor or outdoor installation, insulation technology, automation requirements, and applicable utility standards.
The price of a Ring Main Unit depends on several factors, including the rated voltage, number of ways, protection system, insulation technology, indoor or outdoor installation, automation features, and project-specific requirements.
