KJG-Y Mining Explosion Proof Intrinsically Safe High Voltage Vacuum Feeding Switch Used with Movable Transformer Substation

KJG-Y Mining Explosion Proof Intrinsically Safe High Voltage Vacuum Feeding Switch Used with Movable Transformer Substation

Use
This vacuum switch is used in coal mine and places where are filled with methane, coal dust or explosive mixed gas, in the three-phase ungrounded power grid of AC50Hz,voltage 6KV or 10KV, current range is 50A~630A. Combined with our product BXB series low voltage protection box, protects and measures the movable transformer substation.

Meaning of type

Technical descriptions
