TRVV Drag Chain Cable – High-Flexibility for Industrial Motion Systems

The TRVV drag chain cable is engineered for applications demanding continuous flexing and rapid movement. Offering a bending life exceeding 5 million cycles, this cable combines waterproofing, oil resistance, cold endurance, UV resistance, abrasion resistance and flame retardancy. It is the preferred solution for power and signal transmission in cable carriers, cable tracks, and automated machinery.

Designed for dry or damp indoor environments, TRVV cable handles free, unguided, continuous reciprocating movement without strong tensile stress. It excels in industrial settings with frequent bending, such as woodworking machinery, CNC machine tools, automated logistics and material handling conveyors, and crane systems.

4. FAQ

What is TRVV cable used for?
TRVV drag chain cable is primarily used for power and control connections in cable carriers, automated machine tools, material handling conveyors, and any application that requires continuous flexing movement without forced guidance. It is suitable for dry or damp indoor industrial environments.

How many bending cycles can TRVV cable withstand?
The cable is tested for a bending life of over 5 million cycles under proper installation conditions. Following the minimum bending radius (15 × OD for moving applications) is critical to achieving this lifespan.

Is TRVV cable resistant to oil and UV?
Yes. The outer jacket is formulated from a special modified PVC that provides excellent resistance to industrial oils, UV exposure, and abrasion. This makes the cable suitable for near-window production lines and areas with incidental oil contact.

What do the core color codes mean on TRVV cables?
For conductor sizes up to 0.5 mm², cores are individually color-coded (brown, black, blue, violet, pink, orange). For larger cross-sections (≥ 0.5 mm²), cores use black insulation with white numbers. Cables with three or more cores include an optional green/yellow ground conductor.

What is the voltage rating of TRVV cable?
The cable is rated 300/500 V for conductors equal to or above 0.5 mm², and 300/300 V for conductors smaller than 0.5 mm². The test voltage is 2500 V, confirming the reliability of the insulation.

Can TRVV cable be used outdoors?
TRVV cable is designed for indoor installations, including damp environments. While it is UV-resistant and can tolerate some outdoor exposure, it is not a dedicated outdoor-rated cable for permanent outdoor use. For fully outdoor dynamic applications, please contact us for a tailored recommendation.

What bending radius should I plan for?
For fixed installation, use a bending radius of at least 4 times the outer cable diameter. For moving installations in drag chains or cable carriers, the minimum bending radius is 15 times the outer diameter. Adhering to these limits ensures maximum cable life.
