- Commodity name: XGN-12 high-voltage cabinet
- 产品特点: Compact structure: Only 50% of the volume of ordinary switchgear, saving 2 installation spaces. High safety: It has a "five-proof" interlocking function to ensure operational safety; a pressure relief channel is set to prevent accidents caused by internal arcs 27. Modular design: The cabinet is divided into circuit breaker room, busbar room, cable room and relay room, each room is independently separated, which is convenient for maintenance 27. Environmentally friendly and energy-saving: Air insulation or solid insulation technology is used, without SF6 gas, which meets environmental protection requirements 411. Intelligent monitoring: Supports remote monitoring and data transmission, suitable for smart grids 1112.
The XGN-12 high-voltage switchgear is a fixed type AC metal-enclosed switchgear widely used in power systems for receiving and distributing electrical energy. It features a compact structure, flexible operation, and reliable safety, suitable for indoor installation, especially in power plants, substations, industrial and mining enterprises, and high-rise buildings.
Product Appearance and Internal Structure
Appearance: Made of high-quality cold-rolled steel plate or epoxy resin material, with a corrosion-resistant coating sprayed on the surface, simple and beautiful in appearance.
Internal Structure:
Circuit Breaker Compartment: Located in the lower front part of the cabinet, equipped with a vacuum circuit breaker, flexible operation.
Busbar Compartment: Located in the upper rear part of the cabinet, the busbars are arranged in a product shape to save space.
Cable Compartment: Located at the rear bottom of the cabinet, supporting insulators and voltage monitoring devices.
Relay Compartment: Located in the front upper part of the cabinet, installing relays and secondary components.
Application Scenarios
Power Plants and Substations: Used for power distribution and protection.
Industrial and Mining Enterprises: Providing power support for factories and workshops.
High-rise Buildings and Commercial Complexes: Suitable for power distribution terminal projects.
New Energy Field: Such as photovoltaic and wind power projects' power distribution systems.

1. Normal operating conditions
The normal operating conditions for the XGN-12 switchgear are as follows:
Indoor ambient temperature
Maximum temperature
+40°C
Daily average not exceeding
+35°C
Minimum temperature
-15°C
Indoor ambient humidity
Daily average relative humidity
95% and below
Monthly average relative humidity
90% and below
Installation site altitude
1000m and below
Seismic intensity
No more than 8 degrees
The installation location should be free from fire, explosion hazards, severe pollution, and chemical corrosion.
2. Special operating conditions
For special operating conditions, please consult the manufacturer. The manufacturer and the user should reach a consensus on the special operating conditions.
The reduction in air dielectric strength at altitudes above 1000m has been considered in the design.
If the ambient temperature exceeds the limit, compensation or current limiting is made in the design of the busbars and branch busbars. Installing ventilation devices inside the cabinet will help with heat dissipation.
3. Notes:
If the humidity is high and the temperature fluctuates rapidly and significantly in the switchgear operating area, there is a risk of condensation. Therefore, the user should ensure that the heater is running 24/7 when the switchgear is in standby or operation! However, it can be turned off during high-current operation.
