TE Connectivity (TE) Raychem® high voltage busbar insulation tape (HVBT) is a heat shrinkable, adhesive coated tape which provides insulation enhancement and protection against accidentally induced flashover. HVBT tape is designed to combine the integrity of a heat shrinkable tubing with the versatility of a wraparound product. HVBT tape is quick and easy to install. Upon application of heat the tape shrinks and the adhesive lining melts amalgamating the overlapping layers, to produce a complete lap to lap seal. A single layer of HVBT tape, two-thirds overlapped, will provide AC voltage withstand (flashover protection) to at least 17.5 kV increasing to 36 kV if a second layer is applied. Although HVBT tape will adhere to itself and other insulating materials, it will not adhere to metal or porcelain, allowing easy removal for maintenance. HVBT tape offers a simple and effective solution to the problems of retrofit insulation of busbars, particularly where existing equipment cannot be dismantled. It can be used for indoor and outdoor applications and is easily installed over a wide variety of shapes, including complex connections.
