Sleeves

A sleeve is a tube-shaped insulating covering placed over conductors, cable splices and connection ends to provide electrical insulation and thermal and mechanical protection. It is used to insulate lug and terminal block ends in panel wiring, in cable splices and repairs, for busbar insulation, on motor and transformer winding ends, and in heater and oven connections. In this category, standard heat-shrink sleeves, adhesive-lined shrink types, fiberglass and silicone-coated fiberglass sleeves, and ready-made sleeve sets are in subgroups; the products are from brands such as Woer, Isıso and Konsan. First determine the sleeve type according to the ambient temperature and sealing need; then choose the inner diameter according to the cable or splice diameter and the color according to phase and circuit marking, and for shrink types also check the shrink ratio. Heat-shrink types shrink when heated and sit tightly on the surface, while fiberglass types do not shrink and are used on conductors that operate at high temperatures. Because some products are sold by the meter and some as rolls or lengths, read the sales unit on the product page.
