High and low voltage switchgear

HTXGN-12 Environmentally Friendly Gas-Insulated Ring Main Unit (RMU) is a distribution switchgear that utilizes vacuum interrupters for arc extinction, with eco-friendly gas as the primary insulation medium and minimal solid insulation supports. The main circuit is completely unencapsulated. During normal operation, it maintains zero gauge pressure or slight positive pressure (gas tank pressure ≤0.02MPa), while meeting all air insulation requirements for phase-to-phase and phase-to-ground insulation at zero gauge pressure.

GTXGN-12 AC Metal-Enclosed Solid-Insulated Ring Main Unit (RMU) is a fully-insulated, fully-sealed and maintenance-free solid-insulated vacuum switchgear. All high-voltage live parts are molded with high-performance epoxy resin, integrating vacuum interrupter, main conductive circuit and insulation supports into one solid unit. Functional units are connected through fully-insulated solid busbars, making the entire switchgear immune to environmental impacts, ensuring operational reliability and personnel safety.

HXGN-12 AC High Voltage Vacuum Ring Main Unit (hereinafter referred to as "RMU") is designed for 50Hz, 12kV AC power systems. It is widely used in industrial and civil cable ring networks and power supply terminals.

The XGN-12 Fully Insulated Gas-filled Ring Main Unit (RMU) is widely used in 10kV/6kV distribution systems and serves as the preferred switching solution for substations and power distribution networks in urban and rural areas. The switchgear adopts a modular unit design, allowing flexible configurations for diverse applications. It includes two main types: fixed-unit assemblies and expandable units, meeting the demands of compact and adaptable switchgear solutions in various substations.

 This series of low-voltage withdrawable switchgear is a combined cabinet type using standardized modules factory-assembled (FBA). The switchgear is suitable for power plants, substations, petrochemical plants, metallurgical rolling mills, transportation energy facilities, light industry/textile plants, as well as residential complexes and high-rise buildings. It serves for power conversion, distribution and control in AC power systems (50-60Hz) with rated operational voltage up to 660V.

The GCS Low-Voltage Withdrawable Switchgear is designed for power distribution systems in industries such as power plants, petroleum, chemical, metallurgy, textile, and high-rise buildings. It serves as a complete low-voltage power distribution solution in large-scale power plants and petrochemical systems where high automation and computer interface capabilities are required. The switchgear operates in three-phase AC systems with a frequency of 50(60)Hz, rated operational voltage of 380V(400V) or (660V), and rated current up to 4000A.

The GGD AC low-voltage distribution cabinet is designed for power distribution systems with AC 50Hz frequency, rated operational voltage of 380V, and rated current up to 3150A. It serves power plants, substations, and industrial enterprises for power conversion, distribution and control of motors, lighting and other distribution equipment. Developed in accordance with requirements from energy authorities, power users and design institutes, the GGD cabinet embodies the principles of safety, economy, rationality and reliability.
