Abstract
The invention relates to a de-icing type OPGW cable with a temperature sensing function. The OPGW cable is formed by combination of an optical unit, heating units and stranded wires, wherein a center part is surrounded by the optical unit, the heating units and the stranded wires, the stranded wires are subjected to primary intertwisting and secondary intertwisting, the optical unit is formed after placing temperature sensing fiber and an optical fiber unit in a stainless steel tube, filling the stainless steel tube with water-blocking factice and then conducting seamless welding, and each heating unit is formed after seamlessly welding a stainless steel tube protection layer outside an insulation sheath of a heating conductor. The OPGW cable has the advantages that when heavy icing occurs on a circuit, ice on the cable is molten through heat generated after the de-icing heating conductor in the OPGW cable is electrified, so that the load of the cable is reduced, and precise control over de-icing is achieved through the heating function of the heating units in the cable and the temperature monitoring function of the temperature sensing fiber in the optical unit.
