Background

With the extension of urban cable lines, in medium and high voltage cable structures at home and abroad, the traditional structure of copper strip lapping and wrapping has been replaced by a new copper wire sparse wrapping structure technology gradually in terms of technical shielding layers required for electric field shielding, conducting capacitance current and short-circuit fault current and improving lightning protection characteristics. Regulations for copper wire sparse-winding shielding according to national standards: the average gap between adjacent copper wires is not more than 4mm, and the gap between any two adjacent copper wires is not more than 8 mm. When the gap between adjacent copper wires is too large, namely the copper wires are separated from the semi-conducting layer and contact with the semi-conducting layer too long, the axial potential distribution of the cable is uneven, the longitudinal voltage component is increased, local flashover is caused, line faults are caused, loss is increased due to the increase of capacitance current, and therefore the allowable temperature rise caused during fault short circuit is increased. The adjacent clearance of messenger dredges around the copper wire both satisfies standard requirement and evenly distributed is on shielding sinle silk surface, and current copper wire is dredged around the structure and is used circular copper wire or oval copper wire, is difficult to be that the copper wire evenly distributed is on sinle silk surface, and is difficult to weave for copper wire thickness is inconsistent.
