3M BBI-A Heat Shrinkable Tubing for Bus Bars

3MTM Heat Shrinkable Tubing for Bus Bar BBI–A Series is designed for insulating rectangular, square and round bus bar rated from 5 kV through 35 kV. It will also cover and insulate inline bolted connections of rectangular bus bars. The tubing meets the requirements of ANSI/IEEE Standard C37.20. The standard tubing lengths are 20 feet (6,1 m) and 50 feet (15,2m).

3M BBI–A Tubing is made of a specially formulated cross-linked polyolefin. The tubing is colored orange-red. The material has high resistance to splitting, good solvent resistance and excellent tracking resistance properties. The tubing shrinks easily with industry standard methods, forming an aesthetically appealing insulation cover.

Applications For insulating electrical bus bars per ANSI/IEEE Standard C37.20:
 For 5, 8, 15, 25 and 35 kV voltage ratings
 For rectangular, square and round bus bars
 For inline bolted connections of rectangular bus bars
 For copper or aluminum bus bars
 For use in metal-clad switchgear
 For use on metal-enclosed bus bar
 For use with substation switchgear
