Interrupter Switch (Air-Outdoor)


◆ Use a highly reliable interrupter unit
◆ Excellent arc interruption method
◆ Excellence proven by export

  • Small and light, which makes installation and transport easy.
  • Strength needed for operation has been reduced.
  • Is remotely controlled. On-off status can be confirmed on the ground.
  • It has high structural stability.
  • Arc interruption is very discrete in the case of load make/break, which prevents expulsion of gas or fire.
  • Current carrying part is made up of copper or copper alloys.
  • TR208 (ANSI C 29.9) has been used as a base insulator.
