Low-speed Drag Chain Cable

The conductor is made of multiple strands of ultra-fine twisted oxygen-free copper wire with good flexibility. The tinned copper mesh braided shield has a shielding density of over 80% and strong anti-electromagnetic interference capability. The insulation and sheath are made of special modified elastomers, which are waterproof, oil-proof, wear-resistant, and weather-resistant. They can withstand mechanical external forces and are suitable for industrial frequent bending scenarios.

Product Description

TRVVP series towed chain cable is a type of shielded towed chain cable. Its conductor is made of multi-strand ultra-fine finely stranded oxygen-free copper wires. The insulation layer is made of special mixed PVC or modified elastomer material, and the sheath is generally made of specially improved PVC. The cable adopts tinned copper mesh braided shielding, with a shielding density usually over 80%, which can effectively resist electromagnetic interference. It is suitable for dry or humid indoor environments and is often used in industrial scenarios requiring frequent bending, such as woodworking machinery, machine tool processing equipment, and logistics conveying systems.

It is mainly used as a power transmission cable for long-term reciprocating movement in towed chains of equipment like machine tools, robot system integration, and industrial automation devices.
