Bus Bar Insulating Heat Shrinkable Tubing

Voltage Class 1kV~36kV

Medium and heavy wall heat shrinkable tubing for protection and insulation of bus bar against accidents caused by electrified bare bus bar.

 

Applications

          Bus bar insulation and protection

          In switchgear cabinets where space is limited and air spacing between bus bars need to be kept at minimal

 

Features/Benefits

         Reduces bus bar clearance requirements^* , allow designers more freedom in designing switchgear cabinets when space is premium

          Protects against accidental flashover up to 36kV

          Protects against short circuit and electrical leakage caused small animals

          Protects against corrosion, dirt and other contaminants that may cause accidental flashover

          Halogen Free (optional)

          Flame resistant with oxygen index higher than 27 (optional)

          Available in continuous length roll form for convenient and economical installation

 

Temperature Range

       Operating Temperature  : -40 ºC ~ 105 ºC

       Shrink Temperature              : 125 ºC

 

Colour

       Red, Yellow, Black, Green
