The XGN gas-insulated switchgear is an SF6-filled fully insulated ring network switchgear independently developed by our company. It has been recognized as a high-tech product of Zhejiang Province. Widely used in 24kV/10kV power distribution systems, it is the preferred switchgear for urban and rural users. This product adopts a modular unit structure, which can be combined in different configurations according to usage requirements. It is divided into fixed unit combinations and expandable unit combinations, meeting the flexible needs of compact switchgear applications.
The XGN switchgear features a fully sealed structure where all live parts and switches are enclosed in a stainless steel shell. The entire switchgear is not affected by external environmental conditions, ensuring high operational reliability and personal safety and achieving maintenance-free operation. With advanced insulation and shielding technology, this product can perform reliably even under extreme conditions, offering an indoor operational lifespan of over 30 years.
The XGN gas-insulated switchgear primarily consists of the following parts:
This product's advanced design and superior performance make it suitable for various modern distribution systems, especially for stable long-term operation in harsh environmental conditions.
