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.

SPS Medium Voltage Busbar Tube

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.

 

SPS BMT and BTT Heat Shrink Busbar Tubing Features

  • Substantially improves clearance dimensions within installations
  • Highly flexible for use on straight or angled bars
  • Available on spools for reduced waste
  • Medium wall (BMT) and Thick wall (BTT) allows substantial reductions in Ph-Ph and Ph-E clearances compared with air insulated systems
