Armoire de commande isolée au gaz SF6 de la série X-40.5
Armoire de commande isolée au gaz SF6 de la série X-40.5
The X series gas-insulated switchgear (C-GIS) is a new generation of switch product developed by Yongcheng Intelligent Technology Co., Ltd. with independent intellectual property rights. Its interior uses low-pressure SF6 gas as the insulating medium, and vacuum circuit breakers and three-position switches are the main primary components. They are sealed in an air-filled compartment, and the air chamber is formed by welding with 3mm thick high-quality stainless steel plates, which are not affected by the environment. It features reliable operation, ensuring safety, a compact structure design, small space occupation, maintenance-free, and long service life.
The X series switchgear is a complete set of distribution equipment for 40.5kV three-phase AC 50Hz single busbar and single busbar sectional systems. It can be applied in high-altitude working environments of 5500 meters. It is mainly used for power generation companies, small and medium-sized generator power supply, industrial and mining enterprises' power distribution, as well as power system substations' receiving, transmitting power, and starting of large high-voltage motors, implementing control, protection, and monitoring.
