HBXGN-12 Environmentally Friendly Air-Insulated Ac Metal-Enclosed Switchgear

The HBXGN-12 Environmentally Friendly Air-Insulated AC Metal-Enclosed Switchgear is a medium-voltage power distribution device designed for use in three-phase AC systems with a rated voltage of 12kV and frequency of 50Hz.

Product Advantages
Environmentally Friendly Insulation
Utilizes air instead of SF₆ gas, helping to reduce the impact on the environment.Complies with growing requirements for green and sustainable energy systems.

Operational Safety
Equipped with mechanical interlocking systems between the main switch, grounding switch, and doors to assist safe operations.The fully enclosed metal shell helps limit exposure to energized components.

Adaptability and Modularity
Modular design allows for easy expansion and reconfiguration as system demands change.Various functional units such as load break switches, vacuum circuit breakers, and fuse protection modules can be integrated flexibly.

Reduced Maintenance Requirements
Air insulation eliminates the need for gas pressure monitoring and handling procedures.Components are arranged to support front access, simplifying inspection and maintenance.

Product Applications
Urban Power Distribution
Applied in medium-voltage distribution networks within residential, commercial, and mixed-use areas.Suitable for installations in buildings, substations, and kiosks where compact and safe solutions are needed.

Industrial Facilities
Used in light and heavy industrial environments for internal power distribution and protection of key equipment.Helps support uninterrupted operations in manufacturing plants, refineries, and production lines.

◇Environmental temperature: maximum temperature:+40 ℃, minimum temperature:-25 ℃, 24-hour average temperature: s 35 ℃；
◇Environmental humidity: Maximum average relative humidity: 24-hour average s 95%, monthly average s 90%
◇Altitude: s 1500 meters (conventional type, under standard inflation pressure), special instructions are required for>1500 meters
◇Special conditions: For special operating conditions beyond the normal operating environment, we can negotiate with our company in advance.

◇All live parts are sealed in an air box, which is welded with stainless steel and filled with 1.4 bar of dry air. The protection level of the air box reaches IP67.
◇Install a pressure gauge in the gas box, which can monitor the gas pressure in real time.
◇An explosion-proof membrane is installed at the bottom of the gas box. When an internal fault causes a pressure increase, the explosion-proofl membrane bursts and releases internal pressure. And release the gas towards the rear to prevent injury to the operators in front of the cabinet.
◇The switchgear has passed internal arc test, IAC-AFLR/20kA, 1s.
