Wire-cable structure for electrical overhead lines

摘要

A wire-cable structure for electrical overhead lines which can be used mainly for transmission-line networks in the low and medium voltage ranges. In the case of the wire-cable structure according to the invention, the electrical lines are arranged in a plurality of layers and are twisted in a helical shape. The essence of the wire-cable structure proposed is that lines having the same cross-section are provided in each layer, the lines of at least two adjacent layers have a different cross-section, the twisting direction and twisting pitch of the lines is the same in all the layers, and the lines are deformed as a consequence of the compression of the wire cable.
