The invention provides an overhead power transmission conduction wire, which has the advantages of easy manufacturing and processing, low manufacturing cost and high diameter-expanding rate. The overhead power transmission conduction wire comprises a steel core and an aluminum wire, wherein the steel core is arranged at the central position of the most inner layer, and the aluminum wire is arranged outside the steel core and consists of a plurality of aluminum single wires intertwisted together. The overhead power transmission conduction wire further comprises one or more supporting pieces which are made of a non-metallic material and are arranged outside the steel core. The supporting pieces are made of one or more of high density polyethylene, PVC, plastic, nylon or paper-characteristicmaterials. The shape of the aluminum single wires is one of roundness, Z shape, arch, sector and human head shape. The overhead power transmission conduction wire uses the supporting pieces to easilyhave ...

The invention discloses an ice-snow melting wire and an ice-snow melting method by use of the same. The wire comprises a steel core (2) and an aluminum wire layer (1) covering the outside of the steel core. The ice-snow melting method by use of the wire comprises the following steps: switching current of the wire transmitting power through the aluminum wire layer (1) onto the steel core (2) under normal weather conditions; allowing the current to pass through the steel core (2); emitting heat through the steel core (2) to melt ice; and switching the current onto the aluminum wire layer (1) again after ice-snow on the wire is melted. The wire can eliminate covering ice seriously formed on the surfaces of power transmission lines on the premise that the manufacturing cost of the wire is not obviously increased.

The invention discloses an ice-snow melting wire and an ice-snow melting method by use of the same. The wire comprises a steel core (2) and an aluminum wire layer (1) covering the outside of the steel core, wherein an insulating layer (3) is arranged between the aluminum wire layer (1) and the steel core (2). The ice-snow melting method by use of the wire comprises the following steps: switching current of the wire transmitting power through the aluminum wire layer (1) onto the steel core (2) under normal weather conditions; allowing the current to pass through the steel core (2); emitting heat through the steel core (2) to melt ice; and switching the current onto the aluminum wire layer (1) again after ice-snow on the wire is melted.
