Gas Insulated Switchgear
Features


Insulation
Thanks to our advanced electric field analysis and optimum insulation design we can offer 30% higher performance than standard in short-duration power-frequency and lightning impulse withstand voltage


Thermal current

[Our technology of the heat analysis according to interrupting part arrangement and the using of high quality materials have secured 15 to 25% of allowance at the temperature rising test.]

Mechanical endurance
● CB secures M2 class(10000 operations)
● DS and ES secure M1 class(2000 operations)
