Conductor Support
The Conductors is supported on 1,2,3 or 4 Sets of Insulators depending upon the diameter and the Fault Level. The Conductor is held by the insulators by a Slip Joint and allows it to move axially with respect to the enclosure to cater to differential expansion thereby reducing stress on the insulators.
Spring Loaded Insulators
All the support Insulators are internally Spring Loaded to allow the conductor to move in radial directions. This facilitates the Conductor to align itself to the Magnetic Centre of the enclosure during short circuit, reducing stress on the insulators.
Insulator Replacement
Since the Conductor is not clamped to the Support Insulator, it is possible to remove for routine maintenance or replacement without disturbing the Conductor.
Enclosure Support
The Enclosures of the IPB are supported on SMC/DMC insulators. The enclosure Supports are designed to allow for the expansion and contraction of enclosure during varying ambient and load conditions.
