15KV GIS metal clad switchgear company
Your Premier GIS Metal Clad Switchgear Company
15KV gas insulated switchgear(GIS) is a medium voltage(mv) metal-clad gas insulated switchgear which applicated in outdoor and indoor 3 phase AC secondary power distribution system in utility and substations.
Metal-clad switchgear is one of three common types of metal-enclosed switchgear as defined in ANSI standard.
The technical specification according to IEEE standard and IEC standard. As one of the leading manufacturer of metal clad switchgear, our products quality is even higher technical level than these standards.

15KV gis metal clad switchgear has the advantage of perfect arc resistant function which means the arc flash will be extinguished in the full seal SF6 tank. This function could enhance the safety of the operators. The metal-clad switchgear could be customized according to customer’s specifications.
What’s the meaning of customization? It means all the components technical data could be customized, the wiring diagram design and construction could be adjusted too.
The another advantage of metal clad switchgear is the ease of maintenance, in some applications, the switch remains in “on” position except for yearly shutdown, and in some others, the applications need the equipment switch from “on” to “off” frequently.
