UL/CUL 20936 drag chain shielded data cable

Drag Chain Cable, also known as tank chain cable or drag cable, is a high-performance cable specially designed for reciprocating motion and continuous bending applications. It is widely used in industrial automation equipment (such as robots, CNC machine tools, logistics conveying systems) and other scenarios where cables need to move repeatedly in the drag chain system. The following is a detailed introduction to the drag chain cable:

The structure design of cable drag chain structure with special design, so as to adapt to frequent bending and mechanical stress requirements:

Conductor:material: high purity copper conductor (usually a tin plated copper). Structure: the multi-strand fine copper wire twisted (usually the Class 5 or 6 Class level), to ensure high flexibility.

Insulation:material: commonly used PVC, TPE (thermoplastic elastomer) or PUR (polyurethane). Role: isolated conductor, provide excellent electrical insulation properties.

Fill layer:material: common aramid fiber or similar materials. Function: enhance the tensile strength and flexibility of the cable.

Shield (optional) :structure: aluminum foil shield or copper wire braided shielding. Effect: effective shielding electromagnetic interference (EMI).

Sheath layer:material: PVC, commonly used PUR or TPE. Features: wear-resisting, oil resistant, resistant to chemical corrosion, to adapt to the industrial environment.

The performance characteristics of high flexibility, especially suitable for frequent bending and dynamic applications.

Tensile strength: fill layer design enhance tensile performance, prevent cable in the drag chain pulled apart or cause drag mark. Wear resistance, abrasion resistance, sheath material to adapt to the mechanical stress in the drag chain system. Resistance to chemical corrosion resistance, suitable for industrial environments such as oil, acid and alkali.

Shielding performance (optional) : resistance to electromagnetic interference, suitable for high interference environment.

Temperature range:

working temperature range is commonly – 40 ° C to 90 ° C

(according to different materials, some models can reach higher temperature).

Flame retardant, flame retardant standard (such as UL VW1 or IEC 60332).

Common types of power cable drag chain:

used to transmit power, high power equipment is suitable for motor.

Signal cable drag chain:

used to transmit control signals, suitable for low power devices such as sensors, encoders.

Hybrid cable drag chain:

include the power cord and signal lines, suitable for integrated wiring. Shielding type cable drag chain, belt shielding layer, suitable for high interference environment. Halogen-free cable drag chain, zero halogen sheath material, environmental protection and suitable for high security requirements
