HXGN-12 Indoor AC Metal-Enclosed Ring Main Unit (RMU) Switchgear

Product Introduction

• The HXGN-12 Indoor AC Metal-Enclosed Ring Main Unit (RMU) Switchgear is designed for three-phase AC, 50Hz, 10kV systems to receive and distribute electrical energy. The switchgear can be equipped with load switches of types FN5, FN11, FN12, FN16, or FN21, making it ideal for ring network supply systems or dual-circuit radial supply systems. It can also be integrated into prefabricated (packaged) substations, making it a preferred solution for urban and rural network modernization projects.
• The HXGN-12 box-type fixed AC metal-enclosed RMU is a newly developed switchgear designed and manufactured in-house.

Application Scenarios

• The HXGN-12 switchgear is suitable for indoor distribution systems with a three-phase AC rated voltage of 12kV and rated frequency of 50Hz. It is ideal for:
• Factories and industrial workshops
• Residential communities and high-rise buildings
• Schools, parks, and other public facilities
• It can be used for ring network supply or terminal power distribution.
• The switchgear can be equipped with VEI ISARC-1 or ISARC-2 load switches, or domestic equivalents such as FN11-12 load switches and combination devices with similar specifications.

Environmental Conditions

• Ambient temperature: +40°C maximum, -25°C minimum
• Altitude: up to 1000m
• Relative humidity: daily average ≤95%, monthly average ≤90%
• Surrounding air must be free of corrosive or flammable gases, water vapor, and other severe pollution
