Neutral Isolator is the disconnector switch used in power utilities to separate equipment either from the energy source or the ground.
D-Switch – PESTECH’s branding for neutral isulator. Its robust and reliable design has been fully typed tested to the International Standard (IEC 62271 – 102 & IEC 60694 & certified by ASTA)
This disconnector switch is a “Double Break” isolator complete with manual or motorized operating mechanical drive suitable for both vertical and horizontal mounting.
- Special designed fully tinted copper clamp provides adequate contact surface and supported by 2 stainless steel compression spring to provide adequate contact strength to withstand 2 seconds short time current test.
- Central rotating shaft base consist of double bearing for smooth operation and the bearing housing is packed with graze on assembly and scale; eliminating the need for any maintenance.
- Galvanized steel based has a very rigid design to fix the 3 numbers of insulators levelly. Adjustable rod clamp for the vertical drive rod allows on site adjustment.
