1. non-tightening round conductor belongs to the regular stranded conductor, stranded, the conductor is not after the pressure wheel or tightening mould will conductor tight pressure, stranded conductor between the single line is a natural gap, the conductor is round, * for a common one, such as often seen in the stranded conductor of the electric wire and steel-core aluminium stranded wire and so on belongs to the non-tightening of the conductor.
2.tight circular conductor is based on non-tight circular conductor, in the stranding, the conductor is through the round pressure wheel or round tight pressure mould will conductor tight pressure, reduce the gap between the stranded conductor single line, the conductor is still round, the cross-sectional area of the conductor remains unchanged, but the conductor outer diameter becomes smaller, can reduce the amount of cable insulation and sheath materials and reduce the outer diameter of the finished cable. Tightly pressed round conductors are generally used for low-voltage, medium-voltage and high-voltage power cables and overhead insulated cables.
3.forming conductor is the conductor of the cable in the stranded, the conductor is after the fan or tile pressure wheel will conductor tight pressure fan, tile and semi-circular conductor, the conductor into a certain shape so it is called forming conductor. Tight pressure can also reduce the gap between the single line of stranded conductors, prefabricated cable insulation core in the combination of tight cable, eliminating the need for filler material, winding, lining, armouring and outer sheath and other materials can be reduced, effectively reducing the cable’s outer diameter. Formed conductors are mainly used for low-voltage power cables.
