Heatshrink

Heavy Wall Strain Relief Sleeves

AHW

Description

AHW is a non flame retardant heavy wall heatshrink sleeving designed for strain relief of heavy connectors, where flexing of cable at the cable/connector interface can lead to damage of the conductor and ultimately failure. AHW addresses this problem by dissipating the bending force over a larger radius and away from the connector/cable interface.

 

Features

  • Shrink Ratio 2 : 1 and 3 : 1
  • Operating temperature – 35 to 125°C 
  • High chemical resistance
  • Excellent mechanical and abrasion resistance
  • Colours — Black and neutral
  • Minimum shrink temperature 120°C

Applications

  • Mechanical strain relief at cable/connector interface
