The main function of an insulating sleeve is to provide electrical insulation and protection for wires and cables. It helps to prevent short circuits, electrical shocks, and damage to the conductors by isolating them from each other and from external conductive materials.
The core function of an insulating sleeve is to provide insulation protection. It covers the surface of wires, cables, or other electrical equipment, effectively isolating the current to prevent current leakage or short circuits, thereby ensuring the safe and stable operation of the electrical system.
