Frequently asked questions
What does dual-wall / adhesive-lined do?
A hot-melt inner layer flows when heated and seals the assembly against moisture and corrosion — used for outdoor and buried joints.
Halogen-free vs flame retardant — what is the difference?
Flame retardant slows ignition; halogen-free adds low smoke and no toxic halogens when burned. Both matter in enclosed spaces and transit.
When do I need cold shrink?
Cold shrink needs no heat tool — the support coil is pulled and the silicone recovers. It suits field joints and hazardous areas.
What is heavy / medium wall for?
Thicker walls give more mechanical protection and insulation for busbar and medium-voltage joints.
