Product Description

BBIT-R-Medium wall busbar insulation tube up to 36kV

Made from specially formulated radiation cross-linked halogen free compounds. It can provide high resistance to tracking and arcing, as well as to enhance the insulation properties of bus bar in switchgear and substation. Suitable for application in insulating medium voltage bus bars up to 36kV.
 

Feature

• Minimum shrink temperature: 120°C.
• Halogen free, UV resistant.
• Excellent flexibility, can be used on irregular shapes without creasing of tubing occurring.
• Easily slid into place, even around several bends and on awkward shapes.

 

Ø D: Minimum diameter as supplied
Ø d: Maximum diameter after free recovery
T: Minimum wall thickness after
    free recovery
