Raychem HIGH VOLTAGE Bus Bar Tape (HVBT) is a heat-shrinkable, adhesive-coated tape which provides insulation enhancement and protection against accidentally induced discharge. Raychem tape HVBT is designed to combine the integrity of a heat-shrinkable tubing with the versatility of a wraparound product. It is quick and easy to install. Upon application of heat, the tape shrinks down and the adhesive lining melts which amalgamates the over-lapping layers together, producing a complete lap to lap seal.
A single layer of Raychem tape HVBT, two-thirds overlapped, will provide AC voltage withstand (flashover protection) to at least 17.5 kV increasing to 25 kV if a second layer is applied. Although Raychem tape HVBT will stick to itself and other insulating materials it will not adhere to metal or porcelain allowing easy removal for maintenance
