Medium & Heavy Wall Tube
KB-BT(35KV)35KV Busbar heat shrink tube
Materials: Corss-linked modified polyolefin
˙Operating temperature range:-40℃～125℃
˙Shrink temperature:: above 70℃
˙Shrink ratio:: 2:5:1
˙Features: High-voltage resistance, corrosion resistance, high insulation
˙Applications: Suitable for insulation protection for transformer station buses and high/low voltage switch cubicle buses; compacts the structure of the switch cubicle (reduces the distance in between) and prevents accidental short circuit incidents
