The thermal contraction conduit, a contractile polymer sheath, functions as an insulating barrier for wires, furnishing resistance to abrasion and shielding against environmental factors for stranded and solid wire conductors, connections, junctions, and terminals in electrical undertakings. Featured below is an assemblage of thermal contraction tubing sleeves exceeding 11mm in diameter, encompassing a diverse array of thermal contraction tubes available in varying dimensions and lengths.
