Heat shrinkable tubes
Heat Shrinkable Tubes ASMW and ASHW are medium wall and heavy wall black tubes. ASMW tubes are used for environmental protection of cable termination and insulating the connectors for straight through joints/splice. ASHW tubes are used for mechanical protection and outer sealing of underground straight through cable joints / splice.
• These tubes are manufactured from high quality cross inked polyolefin material.
• Optional hot melt adhesive lining for complete environmental protection and insulation.
• Excellent resistance to weathering, UV rays, chemical and solvents.
• Maximum cut length available up to 1500 mm.
• Custom dimensions, thickness, length & colours available on request.
• Conforms to IEC standard.
