High Voltage Busbar Heat Shrink Tubing

SPS BTT are red coloured, high voltage, thick walled, heat shrink tubes installed onto HV busbars to provide insulation at 6.6kV, 11kV, 15kV, 17.5kV, 24kV and 33kV. The high voltage insulation value of both medium wall (BMT) and thick wall (BTT) busbar heat shrink tubing allows substantial reductions in Phase-Phase and Phase-Earth clearances compared with air-insulated HV systems.

* Flexible heat shrink tubing for use on straight or angled heat shrink busbars

* Heat shrink insulates round, rectangular or round busbars

* Substantial improvement in clearance dimensions within high voltage 11kV-33kV switchgear/transformers

* Insulated busbar systems protected against flashover

HV Busbar Heat Shrink Selection : the maximum heat shrink wall thicknessis only achieved as a result of full recovery in air - the actual wall thickness of heat shrink busbar tubing will vary depending on the size of the busbar profile.

Flashover - an unintended electrical arc between 2 pieces of electrical equipment.
