Heat-Shrink Sleeves

A heat-shrink sleeve is an insulating covering, mostly made of polyolefin, whose diameter shrinks by a certain ratio when hot air is applied, so that it grips tightly the cable or splice it is placed over. It is used to insulate cable splices and lug necks, to mark conductors by color, for busbar insulation and to protect cable ends against moisture. In this category, standard sleeves with a 2:1 shrink ratio, busbar insulation sleeves and adhesive-lined 3:1 types from the Woer, Isıso and Gwest brands are available in colors such as black, red, blue, yellow-green and transparent, in rolls or lengths. Choose the sleeve so that its inner diameter before shrinking is larger than the thickest part of the piece to be covered and its shrunk diameter is smaller than the thinnest part; then check the shrink ratio, operating temperature, voltage rating and color. For outdoor and damp-environment splices where sealing is wanted, adhesive-lined types are used; for insulation and marking inside panels, standard types are used. Some products are sold by the meter and some as 1.22-meter lengths or rolls.

  • Clarify whether the task is connection, cable routing, enclosure distribution or termination.
  • Match dimensions, thread standard, conductor cross-section and IP rating with the cable and panel.
  • Choose housing material and pack quantity according to the mounting environment.
