Product description LVIT is a black, medium wall, flame retarded heat-shrinkable tubing suitable for insulating busbars up to 1 kV. This highly flexible tubing can be used on a variety of curved and bent busbars of both circular and rectangular cross-section. LVIT tubing can be easily installed in a factory environment using an oven or in the field using a gas torch or hot air. LVIT tubing is manufactured in UV resistant material, making it suitable for both indoor and outdoor applications. Applications LVIT is suitable for both enclosed and exposed busbars and for connections in switchgear, substations, motor control centres and other electrical equipment. Features/benefits Compatible with all other products in the Raychem low voltage insulation range Flame retarded Continuous operating temperature rating up to105C High shrink ratio reduces inventory and simplifies product selection Suitable for indoor and outdoor applications Electrical and mechanical performance are retained after cleaning with hydrocarbon solvent Good thermal emissivity and contact with busbars means no derating is needed Can be stored indefinitely at temperatures up to 50C without loss of performance UL approved
