Heat Shrinkable Tubes
  Low Voltage Tubes
  Low Voltage Tubes
 
 
Heat Shrink Low Voltage Tubing GMW and GHW are medium wall and heavy wall black tubing. GMW tubes are used for environmental protection of low voltage cable termination and insulating the connectors for low voltage straight through joints/splice rated upto 1.1KV. GHW tubes are used for mechanical protection and outer sealing of underground straight through cable joints / splice upto 36KV.

  • These tubes are manufactured from high quality cross inked polyolefin material.
  • Optional hot melt adhesive lining for complete environmental protection and insulation.
  • Excellent resistance to weathering, UV rays, chemical and solvents.
  • Maximum cut length available upto 1500 mm.
  • Custom dimensions, thickness, length & colours available on request.
  • Conforms to IEC 60684-3-247 standard.
