XGN-12KV Unit Type AC Metal Closed Ring Network High Voltage Switchgear Electrical Cabinet

Short Description:

XGN-12 series unit type AC metal closed ring network high voltage switchgear electrical cabinet is a fully insulated, fully sealed, and maintenance-free solid insulated vacuum switchgear. All high-voltage live parts are molded with epoxy resin material with excellent insulation performance, and the vacuum interrupter, main conductive circuit, insulating support, etc. are organically combined into a whole, and the functional units are connected by a fully insulated solid busbar. Therefore, the entire switchgear is not affected by the external environment, and the reliability of the operation of the device and the safety of the operator can be ensured. Because the product has the advantages of full insulation, full sealing, and full shielding, it is especially suitable for use in areas with high altitude, high temperature, mixed heat, severe cold, and severe pollution.

Product structure features

Solid insulated fully enclosed switchgear: It is a single or combined main conductive circuit such as isolating switch, grounding switch, main busbar, branch busbar, etc., which is made of solid insulating material as the main insulating medium and conductive connection, and then wrapped and encapsulated with solid insulating medium. Or several modules with certain functions, which can be combined or expanded again with full insulation and full sealing performance. The three-position mechanism adopts an over-center spring design, which has the function of breaking and closing the load current, and can also realize manual and electric operation.

Environment condition

1. Ambient air temperature: -5~+40 and the average temperature should not exceed +35 in 24h.
2. Install and use indoors. Altitude above sea level for operation site should not exceed 2000M.
3. Relative humidity should not exceed 50% at max temperature +40. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20. But in view of the temperature change, it is possible that moderate dews will produce casually.
4. Installation gradient not exceed 5.
5. Install in the places without fierce vibration and shock and the sites insufficient to erode the electrical components.
6. Any specific requirement, consult with manufactory.
