TRVV 3x1.5mm High Flexible Drag Chain Cable from Dongguan Jinxunyuan Wire And Cable Co. Ltd is an exceptional solution for various industrial applications.

Designed with a copper core, Butin PVC insulation, and Butin PVC sheathing, this tow chain cable boasts unparalleled folding resistance, wear resistance, corrosion resistance, oil resistance, bending resistance, and high flexibility. In line with national standards, it is classified as a first-grade product.

TRVV structure:

1. Tensile center
In the center of the cable, according to the number of cores and the space of each core wire crossing area, as far as possible, there is a real centerline filling (instead of filling with some filler or waste plastic as is usually the case). This method can effectively protect the stranded wire structure and prevent the stranded wire from wandering to the center area of the cable.

2. Conductor structure
Cable 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, will produce cable winding phenomenon. A series of long-term experiments have provided the best shielding combination of diameter, length and pitch of a single wire, which has the best tensile capacity.

3. Insulate the core wires
The insulation materials in the cable must not stick to each other. And the insulation also needs to support each strand of wire. Therefore, its reliability can only be proved in the application of high voltage formed PVC or TPE material for millions of meters of cable in the tow chain.

4. Twisted wire
The twisted wire structure must be wound around a stable tensile center at the optimum joint pitch. However, due to the application of insulating materials, the twisted wire structure should be designed according to the motion state, starting from 12 core wires, because the way of bunching should be used.

5. Inner sheath
Armour-type extruded inner sheathing replaces cheap wool material, padding or accessory padding. This method can ensure that the twisted wire structure will not be scattered.

Step 6 Block
When the shield is tightly woven over the inner sheath at an optimized weaving Angle, loose braiding degrades the EMC's protection and the shield quickly fails due to breaking of the shield. The tightly woven shielding layer also has torque resistance.

7. Outer sheath
The outer sheath made of different modified materials has different functions, such as UV resistance, low temperature resistance, oil resistance and cost optimization. But all of these outer jackets have one thing in common, high wear resistance, and do not adhere to anything. The outer sheath must be highly flexible but also have a support function, and of course it should be high-pressure molded."
