In order to reduce the manufacturing cost of the overhead insulated wire (cable), a pressing mold is usually used for pressing the core conductor so as to achieve the purposes of compacting the conductor and reducing the outer diameter, and simultaneously, the discharge among single wires of the conductor is reduced, and the service life of the cable is prolonged. At the in-process that the conductor sticiss, because the relative motion of conductor and mould can produce a large amount of friction heats, if not in time take cooling measure, a large amount of heat are gathered and are made sinle silk surface molecule melt, and the melting material can glue on the moulding-die and glue and pile up, makes the lubricated effect of moulding-die decline, leads to sinle silk surface to produce the burr, causes the damage to next process insulating layer, produces the waste product, can directly lead to whole broken string in the production of the sinle silk seriously, makes manufacturing cost sharply rise.

2. And a natural cooling compaction process is adopted, and the process is compacted in a natural environment without temperature reduction measures. The advantages are low production cost, safety and reliability; the cable core conductor has the defects of poor heat dissipation effect, low compression coefficient and loose compression of the cable core conductor, thereby increasing the outer layer plastic insulation thickness of the stranded wire and increasing the material cost.
