40.5kV SF6 GAS INSULATED C-GIS
AGS-40.5 type indoor gas-insulated l-enclosed switchgear is manufactured by using SF6 gas as insulating medium, combined with vacuum breaking technology, modular design concept and leading production and processing technology. It is suitable for use in public and industrial power distribution networks, infrastructure projects, rail transport, llurgy, petrochemical industry, wharves, ships, drilling platforms, etc., as a means of accepting and distributing electrical energy, as well as controlling, protecting and monitoring electrical circuits.
Product Features
Maintenance-free: Hight voltage part is fully sealed, not affected by the environment, adopting vacuum disconnection technology, high reliability
Modularity: unit independence, high interchangeability, can be customized according to user requirements combination of programmed
Efficient operation and maintenance: easy on-site installation, maintenance, expansion and replacement, plug-in structure, no gas operation on site
Operating scenario: not affected by the altitude, can be applied to 5000m scene
Operating life: adopting all new composite materials, with a service life of at least 30 years
Intelligent: adopting IT and OT technology, online real-time monitoring
