Towed cables, also known as drag chain cables or tank chain cables, are cables designed specifically for high flexibility requirements. Here is a detailed introduction to towed cables:

1. Definition and Characteristics

A towed cable is a cable that can flexibly expand and contract with the movement of the drag chain, and has excellent properties such as wear resistance, bending resistance and torsion resistance. It has a stable structure under external force, can maintain a stable structure in a moving state, and achieves zero displacement.

2. Product Structure

The structure of a towed cable usually includes four parts: sheath, conductor, insulation layer and protective layer:

1.Sheath: Made of high-strength PVC or nitrile rubber material to prevent the cable from being damaged during towing.

2.Conductor: Made of multiple strands of copper or aluminum wires to maintain the stability and reliability of current transmission. The multi-strand conductor makes the cable softer and easier to move with the drag chain.

3.Insulation layer: Also made of PVC or nitrile rubber material to prevent electric leakage and short circuit.

4.Protective layer: Made of low-friction, high-hardness PVC material to further prevent the cable from being damaged during towing.

3. Application Fields

Towed cables are widely used in various industrial occasions with continuous reciprocating motion, especially in the field of mechanical automation. Specifically, it can be used in the following scenarios:

1.Industrial electronic systems, automation equipment, robots, etc.

2.Continuous loading and unloading of large quantities of granular materials, port water transportation, mineral excavation, etc.

3.Stacking and reclaiming operations in granular bulk material storage yards such as power generation industry and cement industry.

4.Mining, electric power, metallurgy, petrochemical, shipbuilding and other industries.

4. Selection Considerations

When selecting a towed cable, the following factors need to be considered:

1.Cable length: Determine the required cable length according to the actual application scenario.

2.Cable diameter: Determine based on the size of the drag chain and the bending radius of the cable.

3.Material: Select the appropriate material according to the working environment and the requirements of wear resistance, temperature resistance and other properties of the cable.

4.Temperature resistance grade: Ensure that the cable can work normally within the working temperature range.

5. Precautions

1.During use, avoid excessive bending or twisting of the cable to avoid damaging the cable structure.

2.Regularly check the wear condition of the cable, and replace the severely worn cable in time.

3.Ensure that the cable is not pulled or squeezed by external forces during towing to extend the service life of the cable.
