Regarding multi-core power cords, in order to ensure the degree of molding and reduce the shape of the power cords, it is generally required to twist them into a circular shape. The twisting mechanism is similar to conductor twisting, because the twisting pitch is relatively large, and most of the twist-free methods are used.

The technical requirements for cabling: First, the twisting of the cable caused by the turning of the absolutely-shaped insulated core;
The second is to prevent the insulation layer from being scratched;
Three-core waterproof power cord.
Most of the cables are completed with the completion of two other procedures: one is filling, the roundness and stability of the cable after the cable is formed.
