Stretch-resistant vibration-damping medium-voltage single-core overhead power cable

Abstract

The utility model discloses an anti-tensile vibration-damping medium-voltage single-core overhead power cable, which comprises an ethylene propylene diene monomer vibration-damping core tube, a galvanized steel stranded wire is sleeved in the ethylene propylene diene monomer vibration-damping core tube, and two layers of rare earth high-iron aluminum alloy fan-shaped conductors are concentrically stranded around the exterior of the ethylene propylene diene monomer vibration-damping core tube to form an aluminum alloy conductor. A PPS fiber woven isolation net, an ethylene propylene diene monomer inner semi-conductive layer, a silane grafted cross-linked low-density polyethylene insulating layer, an ethylene propylene diene monomer outer semi-conductive layer, an aluminum-plastic composite wrapping shielding layer, a ferrite film wrapping layer and a silane grafted cross-linked high-density polyethylene inner sheath layer are sequentially wrapped outside the aluminum alloy conductor. A nylon anti-corrosion layer; and a silane grafted cross-linked high density polyethylene outer sheath layer. The power cable has the advantages of high overall mechanical strength, increased tensile strength, better vibration damping performance, capability of inhibiting fatigue wire breakage and prolonged service life.
