3M™ Tubing BBI-A will handle voltage ranges from 600 VAC to 35 kV, reducing your inventory requirements and saving you time and money. The BBI-A material has a high resistance to splitting, while providing the flexibility to conform to bends in certain applications. Superior split resistance can prevent insulation failures and resulting downtimes. BBI-A is unaffected by normal cleaning fluids and is-resistant to physical damage. Good thermal endurance upto 230 deg F contributes to longer life and more stable performance. Excellent dielectric strength allows the required space between bus bars and metal enclosures to be substantially reduced. Closer spacing reduces both the overall size of the assembly, and the overall cost. Note: bus bar is packaged one roll per case, 20 or 50 ft long.
