The technical performance of XGN49-40.5 (Z) [DXG-40.5 (Z)] indoor gas insulated metal enclosed switchgear (hereinafter referred to as "gas filled cabinet") meets the standards of GB / T11022 "common technical requirements for high voltage switchgear and control equipment" and GB3906 "3 ～ 35kV AC metal enclosed switchgear", with the characteristics of high reliability, maintenance free and less occupation of land; the main technical parameters have reached the international advanced level 。

Product features

1. Modular design is adopted;

2. The sealing box is made of 4-6 mm high quality stainless steel plate welded by manipulator. The air tightness of the box can be maintained for 30 years without air replenishment, and the box is not deformed at high altitude.

3. The incoming and outgoing cables are connected with inner cone insulators by special cable heads;

4. Epoxy resin is used to cast through type current transformer;

5. Intelligent control / protection unit integrating control, protection, measurement and signal is adopted for secondary protection; traditional relay protection can also be used;

6. The main bus connection between cabinets can be realized by using air isolation insulator, which can ensure the electrical insulation and the air tightness in the bus room.
