HTN-12 environmental protection gas ring network cabinet (national network standardization customization)
Product Details
Product overview
The environmental protection gas ring network cabinet uses dry air or N2 as insulating medium, and the vacuum arc extinguishing chamber is used for arc extinguishing. Its isolating switch and arc extinguishing chamber are completely enclosed in a stainless steel gas box of dry air or N2, with full insulation and full sealing design. The gas box is welded by imported stainless steel plate using advanced robot welding technology, and the protection level of the gas box reaches IP67. It adopts a mature structure, easy to install, and fully realizes the requirements of green environmental protection, safety and reliability, compact structure, maintenance-free, and long life. It is a set of high-tech nuclear, Li Pieces and new technologies, new processes, new materials completely environmentally friendly switchgear products. Its main functional units are V unit (circuit breaker unit), C unit (load switch unit) and F unit (load switch-fuse combination unit).
