Towline cable

- Aug 08, 2017-

1. Tensile center

At the center of the cable, there is a true centerline fill as much as possible depending on the number of cores and the space in each core intersection (rather than the usual filling of waste cores made of some filler or waste plastic). This method can effectively protect the strand structure and prevent the strand from being released to the center of the cable.


2. Conductor structure

Cables should choose the most flexible conductor. Generally speaking, the thinner the conductor, the better the flexibility of the cable, but the conductor is too thin, which will cause cable winding. A series of long-term experiments provide the best diameter, length and pitch shielding combination for a single wire with optimum tensile strength.


3. Core insulation

The insulation inside the cable cannot be stuck to each other. Moreover, the insulating layer also needs to support a single strand of wire per share. Therefore, reliability can only be confirmed in applications where high-pressure molded PVC or TPE materials can be used in a multi-million-meter cable for a towline.


4. Stranded wire

The stranded structure must be wound around a stable tensile center at the optimum crossover pitch. However, due to the application of the insulating material, the twisted wire structure should be designed according to the motion state, starting from 12 core wires, because of the bundle twisting method.
