Product Description

12kV SF6 Gas Insulated RMU Switchpanels (Ring Main Unit)

SF6 Insulated Ring Main Unit (RMU)

This sulfur hexafluoride gas insulated switchgear is a high-voltage electrical equipment that uses SF6 gas as an insulating and arc-extinguishing medium.

Core Advantages

Miniaturization: High insulation of SF6 makes the equipment volume more than 50% smaller than air-insulated cabinets
High reliability: Fully enclosed structure, not affected by environmental factors (humidity, dirt, altitude)
Maintenance-free: SF6 gas has high stability with contacts almost non-oxidized in inert environment
Long life: Design life exceeding 30 years
Safety: No fire risk with low operating noise

Application Areas

Substation: Incoming, outgoing and connecting lines of medium and high voltage distribution systems
Industrial electricity: Harsh environments including mining, metallurgy, and chemical industry
Urban power grid: Space-constrained locations such as subways, airports, and data centers
Renewable energy: Boosting and grid connection for wind farms and photovoltaic power stations
