Abstract
The utility model discloses a steel-cored aluminum strand overhead insulated cable, which comprises a cable conductor, and an inner shielding layer and an insulating layer which coat the cable conductor, wherein the cable conductor is formed into a core strand body by an inner core portion which is formed by a plurality layers and a plurality strands of galvanized steel wires on the center of the cable and an outer core portion which is formed by a plurality layers and a plurality strands of electric pure aluminum wires on the outer layer of the inner core in the modes of twisting and pressing, an inner shielding layer is covered on the inner surface of the insulating layer, and the inner shielding layer and the insulating layer are simultaneously squeezed out. The steel-cored aluminum strand overhead insulated cable can improve the tensible strength, conductivity and assurance coefficient of cables, increases the erecting span of overhead cables, reduces poles and towers, saves production cost, improves the vibration resistance property, and prolongs the service span of cables.
Description
Technical field
The utility model relates to cable, exactly is the steel reinforced aluminium conductor aerial insulated cable.

The utility model content
At the deficiency that prior art exists, the utility model aims to provide a kind of tensile strength and conductance, steel reinforced aluminium conductor aerial insulated cable that coefficient of safety is higher.
The technical solution adopted in the utility model is:
A kind of steel reinforced aluminium conductor aerial insulated cable, the internal shield and the insulating barrier that comprise cable conductor and parcel conductor, the inner core that described cable conductor is made of the multi-lever and multi-strand galvanized steel wire that is positioned at cable center and be positioned at the outer field outer core that constitutes by multi-lever and multi-strand electrician fine aluminium lead of inner core and constitute a core bundle body in stranded mode of pressing, the insulating barrier inner surface is covered with internal shield, and internal shield and insulating barrier are extruded simultaneously.
Described inner core is made of center galvanized steel wire and six strands of galvanized steel wires around the center that one is positioned at cable center, and outer core is made of multiply electrician fine aluminium single line.
The thickness of insulating layer of described coating cable conductor is 3mm-4mm, and internal shield thickness is 0.2mm-0.8mm.
The thickness of insulating layer of described coating cable conductor is 3.4mm, and internal shield thickness is 0.5mm.
Described internal shield is a semi-conductive layer, is coated on inner shield conductor periphery uniformly.
Described insulating barrier is the black polyethylene insulating material.
The utility model can improve tensile strength, conductance and the coefficient of safety of cable, increases setting up span, minimizing shaft tower, saving cost cost, the vibration resistance of raising cable, the useful life of prolongation cable of aerial cable.
