A fixed high-voltage switchgear designed and developed by ourselves meets the requirements of the national standard GB/T3906 "3-35kV AC Metal-enclosed Switchgear" and the Ministry of Electric Power DL404 "Technical Conditions for Ordering Indoor AC High-voltage Switchgear", and also meets the requirements of the international Standard IEC298 "1kV above 52kV AC metal-enclosed switchgear and control equipment" requirements, and has two proposed "five prevention" locking function.

HXGN26-12(24) type SF6 ring main unit is a 12kV (24kV) ring main unit which adopts SF6 gas insulation and arc extinguishing, which is designed and developed by Tianan Electric after digesting and absorbing foreign advanced technology and combining with my country's power supply requirements.

The GXGT1-12 (XGN108-12) solid ring main unit is the latest high-performance, green and environment-friendly 12kV ring main unit developed by Tianan Electric, which combines vacuum arc extinguishing and solid insulation technology. All live parts of the product are sealed. In the APG injection-molded epoxy resin shell, adjacent cabinets are connected by plug-in solid insulated bus bars, and the entire switchgear is not affected by the external environment.

The HXGT6B-12 type ring main unit is the latest high-performance, green and environmentally friendly 12kV intelligent ring main unit developed by Tianan Electric that combines vacuum arc extinguishing and (environmental) gas insulation technology.

HXGT6A-12(24) indoor gas-insulated metal-enclosed switchgear is a new generation of ring network switchgear independently developed by Tianan Electric, with a voltage level of 12kV (24kV).

Class 1E KYN44A-12 indoor armored center-mounted AC metal-enclosed switchgear is a novel medium voltage switchgear developed by Tianan Electric according to the environmental conditions of nuclear power plants that meets the requirements of nuclear power plants 1E.

KYN28A-12 type indoor armored center-mounted AC metal-enclosed switchgear (referred to as center cabinet) is a complete set of power distribution equipment for 3-10kV three-phase AC 50Hz single bus and single bus section system.

XGN75-12 indoor gas-insulated metal-enclosed switchgear (hereinafter referred to as XGN75-12 inflatable cabinet) is a high-tech product independently developed by Tianan Electric that adopts vacuum arc extinguishing and SF6 gas insulation technology. The technical level has reached the leading domestic and international level. Advanced level. All high-voltage live components of the product are sealed in a stainless steel box (IP67) filled with SF6 gas of lower pressure (0.03～0.05MPa gauge pressure, 20℃). The main switch adopts a spring-operated vacuum circuit breaker with three stations. The isolation grounding switch of the product has stable insulation performance, and is especially suitable for harsh environments such as high altitude, severe cold, humidity, and pollution. Due to the small footprint of the product, it can be used in places with tight land.
