Heat Shrink Cable Joints & Cable Terminations
SPS High Voltage HV Heat Shrink Busbar Tubing 11kV-33kV
T&D have supplied over 2.5km of various sizes of SPS MV Medium Voltage Heat Shrink Bus Bar Tubing to insulate and protect 25kV bus bars on soft starters. T&D can supply busbar heat shrink tubing to suit Medium Voltage Soft Starters for motor ratings 30-3000A, 1500-15000V, 30KW - 50000KW.
Shrink Polymer Systems BMT and BTT are red medium and thick wall unlined heat shrinkable tubes designed to insulate busbar systems up to voltages of 33kV and to protect against flashover.
High voltage heat shrink busbar insulation tubings provide flashover protection against accidental bridging of straight or angled, rectangular and round HV busbars, 11kV-33kV. HV busbar tubings are suitable for enclosed and exposed bus work and for high voltage connections in switchgear line ups and substations. HV high voltage busbar heat shrink tubes also enable clearance reduction within high voltage electrical insulation applications, 11kV-33kV.
