TRVVSP 2/4/6/8/10/12/16-Core Flexible Drag-Chain Cable, Twisted Pair Shielded Servo Encoder Cable

PVC-Insulated, 600V Rated

The TRVVSP series Flexible Drag-Chain Cable, Twisted Pair Shielded Servo Encoder Cable is designed for servo motor feedback and motion control systems operating under continuous movement. It is engineered to maintain stable signal transmission and mechanical reliability in drag-chain, robotic, and CNC applications where repeated bending and electrical interference are unavoidable.

Manufactured by Shanghai Rousheng Wire & Cable Co., Ltd., this cable reflects long-term expertise in high-flex drag-chain and specialty industrial cables developed specifically for automation and motion control environments.

Built for Continuous Motion and Long Service Life

In servo-driven equipment, cable failure is often caused not by voltage stress, but by mechanical fatigue and signal instability. Repeated bending, vibration, and friction inside cable carriers gradually damage standard control cables, leading to encoder errors and unexpected downtime.

The TRVVSP Flexible Drag-Chain Cable, Twisted Pair Shielded Servo Encoder Cable is engineered to address these challenges through a balanced combination of flexible conductor design, optimized twisting geometry, and layered shielding.

Key Performance Advantages

High Flexibility for Drag-Chain Applications

The cable uses a flexible conductor structure designed to withstand continuous bending. Internal stress is reduced during movement, helping to extend service life in drag-chain and moving-axis installations.

Stable Servo Encoder Signal Transmission

Precision twisted-pair construction maintains consistent impedance for differential encoder signals. This helps preserve signal accuracy in high-speed servo feedback systems where timing and noise sensitivity are critical.

Effective Shielding Against EMI

Each twisted pair is protected by aluminum foil shielding, combined with an overall braided shield. This dual shielding structure reduces cross-talk between signal cores and suppresses external electromagnetic interference from motors and power cables.

Industrial PVC Insulation, 600V Rated

Industrial-grade PVC insulation provides electrical safety and compatibility with common North American servo and automation systems. The outer jacket also offers good resistance to abrasion and general industrial wear.
