The compaction process is mainly used for stranding the insulated conductor, and the bare wire is not compacted generally. And (3) a compacting process: the round stranded conductor is compacted vertically in the first and third processes, and is compacted horizontally in the second and fourth processes; the first and second pressing wheels are 80%, the third and fourth pressing wheels are round, and the pressing amount is 20%; the outer diameter of the round compacted conductor may be compared to the non-compacted conductorThe reduction is 7.2-9.17%, and the filling coefficient (normal twisting) can be improved from 75% to 90-93%. Sector stranded conductor 25-50 mm²Only one vertical compression can be performed; 70mm²And after the outermost layers of the conductors are twisted, three times of pressing are carried out, namely vertical, horizontal and vertical pressing, wherein the first pressing amount is 85%, the second pressing amount has the shaping (two-side) effect, and the third pressing amount has the shaping effect; the filling coefficient of the compacted fan-shaped conductor can reach 90-93%. The compact structure of the electrically conductive core 32, especially the compact structure of several strands of small copper wires, can minimize the gap control after the compact structure, so that the electrically conductive core is not easy to deform and damage due to air gaps in deep sea.

Preferably, the electrically conductive core 32 is circular in cross-section. In the field of sticising, generally more adopt special-shaped compacting machine, after experimental many times, the utility model discloses the preferred circular cross section that adopts, circular cross section has the strongest effect of resistance to compression.

Preferably, the ratio of the cross-sectional size of the conductive core 32 to the cross-sectional size of the insulating layer 31 is 1/1 to 1/2, and the cross-sectional size of the conductive core 32 after being compressed is reduced compared to the conventional one, so that the thickness of the insulating layer 31 can be increased appropriately while maintaining the same diameter as the original cable, and the conductive core 32 can be protected from damage better.

In order to further reduce the bubble content, the insulating layer 31 is fixed on the outer side of the electrically conductive core 32 in a squeezing manner. Therefore, when the insulating layer 31 is processed to the surface of the electric conducting core 32, bubbles are hardly generated, so that the content of the bubbles in the whole electric unit core 3 is greatly reduced, and the deformation caused by the bubble gaps is avoided under the huge pressure of deep sea, thereby ensuring the use reliability of the cable.
