Overhead insulated cable is a special cable used in overhead power lines, with insulation layer and sheath. Compared to bare wires, it significantly improves power supply safety and reliability, effectively preventing short circuits, external interference, and personal electric shock. Its insulation material is usually weather resistant polyethylene or cross-linked polyethylene, suitable for areas with limited space or environmental sensitivity such as urban power grids and forest areas.
