Product Description

　　 Product Overview

　　The XGN□-24 (SF18-24) gas-insulated high-voltage AC metal-enclosed switchgear (SF6 gas-insulated cabinet) is a new-generation, fully enclosed stainless-steel gas-insulated switchgear manufactured using advanced welding, gas charging, and leak-testing technologies. All live components are sealed within a stainless-steel enclosure filled with SF6 gas, and both the gas compartment and the fuse cartridge achieve an IP67 protection rating. Featuring a modular design, it is compact yet highly configurable and scalable, allowing for flexible configuration of combined electrical units and circuit-breaker units. This product is widely used in the construction and renovation of urban power grids, suitable for ring-network and terminal power supply in various distribution systems, and also ideal for integration into prefabricated substations and switchgear stations. It boasts fully enclosed construction, maintenance-free operation, a compact structure, and high reliability.

 

　　 Product Notes

　　Note:

　　1. The parameters of the circuit breaker unit are determined by the intrinsic parameter values of the circuit breaker itself;

　　2. The relevant parameters of the switchgear unit depend on the rating values of the fuse.
