Product overview

XGN□-24(SF18-24) gas insulated high voltage AC metal enclosed switchgear (SF6 gas cabinet) is a new generation of stainless steel fully enclosed gas-filled switchgear produced by advanced welding, gas filling and leak detection technologies. All its live parts are sealed in a stainless steel housing filled with SF6 gas, and the gas box and fuse barrel all reach IP67 protection level. The modular design is compact and can be freely combined and expanded, and the combined electrical unit and circuit breaker unit can be configured. The products are widely used in the construction and transformation of urban power grids, suitable for the ring network power supply and terminal power supply of various power distribution systems, and also suitable for pre-installed substations and switching power stations. It has the characteristics of full closure, maintenance-free, tight structure and high reliability.

Product Notes

Note:

1. The relevant parameters of the circuit breaker unit depend on the parameter value of the circuit breaker itself;

2. The relevant parameters of the combined electrical unit depend on the parameter value of the fuse.
