Structure notes

  • The disconnect switch is made up of three single phases.
  • Each phase uses a V-type structure with a 50 deg symmetrical angle.
  • Main assembly includes pedestal, post insulator and electrical part.
  • For disconnectors with earth switch, listed parts include male and female contacts, blade, driving parts and interlock plate.
  • Main blade can use CJ6 motor mechanism or CS17 manual operating mechanism.
  • Earth blade can be matched with CS17 manual operating mechanism.
  • Installation methods include obverse, side, diagonal and reversal arrangements.
  • Outdoor and indoor use can be arranged according to project requirements.
