HS series heavy wall heat shrinkable tubing. Made of thermally stabilized cross-linked polyolefin, enabling a recovered wall thickness greater than that of the cable jacket replaced. Withstands severe mechanical requirements of U.R.D, submersible and direct burial installations. Tubing, featuring an internally applied sealant, offers protection against moisture and may be used over lead, steel, aluminum, copper, standard plastic and elastomeric insulating materials. Shrink temperature of 120°C. High-impact, abrasion, corrosion and chemical resistance. Rated for 600V, 90°C continuous use. Thermoplastic adhesive liner provides complete environmental protection and insulation. Meets: UL and CSA standards, ANSI C119.1, western underground guide numbers 2.4, 2.5, ICEA and NEMA insulation thickness requirements. Continuous operating temperature: -55°C to 110°C. TB recommended up to 1 kV.
