Flame Retardant - INSULTUBE Halogen Free


	Heat Shrink Low Voltage Tubing GFMW and GFHW are medium wall and heavy wall black tubing. These Tubes are used where high flame retardant is required. GFMW tubes are used for environmental protection of low voltage cable termination and insulating the connectors for low voltage straight through joints/splice rated upto 1.1KV. GFHW tubes are used for mechanical protection and outer sealing of underground straight through cable joints / splice upto 36KV. These tubes are manufactured from high quality cross linked polyolefin material. General Properties Optional hot melt adhesive lining for complete environmental protection and insulation. Excellent resistance to weathering, UV rays, chemical and solvents. Maximum cut length available upto 1500 mm. Customised dimensions, thickness, length & colours available on request. Conforms to IEC 60684-3-247 standard. Meets IP 68 (ingress Protection)
