1. The centerline filler is not the filler of ordinary cables. It effectively protects the structure of the trailer cable and prevents the stranded wire from drifting to the central area of the cable.

      2. Choose a suitable single wire to achieve the best tensile strength, because too thin conductors are easy to cause tangles

      3. Use high-pressure molded PVC or TPE as the core wire insulation material to support each single strand of wire so that the insulation materials in the cable will not stick to each other

      4. The twisting method is adopted, and the design is based on the movement state, starting with 12 cores.

      5. The armored extruded inner sheath replaces cheap wool materials, fillers or auxiliary fillers. This method can ensure that the stranded wire structure will not be scattered.

      6. The shielding layer is braided on the outside of the inner sheath, and the tightly braided method is adopted to make the shielding layer have the function of torsion resistance.

      7. The outer sheath made of different materials has different functions, but its wear resistance and non-adhesion are the same, and it has a highly flexible support function.
