3M Shrinkable Tubing for Bus Bar BBI-A Series 5-35kV

3M 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.
