Description
Description
Application
GT3 is a medium wall co extruded tubing with adhesive.
Provides excellent adhesion to a variety of cable substrates, and various metals.
Ideal for LV joints and termination as core insulation, or as cable sheath replacement in LV and MV joints.
The adhesive layer ensures a water tight seal and eliminates moisture ingress.
The tube is UV and weather resistant.
