Continuously Flexible Halogen-Free PUR Data Cable for Drag Chains
This continuously flexible, halogen-free PUR data cable is engineered for high-cycle operation in drag chains and moving industrial equipment. Its low-capacitance design, compact outer diameter and small bending radius support space-saving installation, while the abrasion-resistant PUR jacket provides reliable protection against oil, chemicals, ozone, UV exposure and mechanical stress.
Key Highlights
Continuously flexible for drag chains · Halogen-free core insulation · Abrasion-resistant PUR jacket · Low capacitance · Compact outer diameter · 7.5 × d dynamic bending radius · Oil and chemical resistant · UV and ozone resistant · Flexible down to -40°C in moving applications · PWIS-uncritical · PFAS-free · RoHS compliant
This unshielded flexible data cable is designed for continuous-motion installations requiring compact dimensions, reliable signal transmission and high mechanical durability.
Typical applications include:
- Drag chains and energy chain systems
- Automated production and assembly equipment
- CNC machines and moving machine-tool components
- Packaging, conveyor and material-handling systems
- Linear robot axes and robotic peripheral equipment
- Compact data, sensor and control connections
- Paint shops and coating equipment requiring PWIS-uncritical materials
- Industrial environments exposed to oil, chemicals, hydraulic fluids, ozone, sunlight or salt water
Its low-temperature flexibility and durable PUR outer jacket make it suitable for continuous movement under demanding indoor and outdoor operating conditions.

THE FACTORY
BEHIND EVERY METER
Founded in 2007 in Foshan, Guangdong, Hulk Electric has grown from a regional producer into a globally recognised manufacturer of customised industrial cable solutions. Our 10,000㎡ facility runs on Toyota Production System lean principles, operated by 150+ skilled professionals producing over 300,000 metres every month.
Every cable you see on this page — including the HK-TRVV series — is engineered, extruded, tested, and shipped from that single facility. No trading company sits between you and the extrusion line.
Source Factory
Direct manufacturer — no middlemen, no markups. You deal with the engineers who run the line.
Deep Customization
Conductor, shielding, jacket compound, colour coding, certification — built to your exact spec.
7-Day Sampling
Rapid samples for new specifications. 15-day lead time on standard production orders.
Global Compliance
35+ certifications covering UL, CE, TÜV, IEC, RoHS and REACH for every major market.
BEFORE YOU ORDER
For stocked configurations listed in the ordering table, MOQ is 100 metres per specification. Custom configurations — non-standard core counts, jacket colours, or special compounds — carry a 500 metre MOQ. Samples of 5–10 metres are available free of charge for qualification testing.
Use shielded (P or PP suffix) whenever the cable runs alongside servo drives, VFDs, or inverters, or when carrying encoder, sensor, or analogue signals. Unshielded is suitable for pure power distribution and simple on/off control lines. If in doubt, our engineering team can review your cabinet layout and advise — this is included with any quotation.
Yes. Send us the existing part number or a sample and we will produce a cross-reference specification with matching electrical, mechanical, and dimensional characteristics. Most cross-references are turned around within 3 working days, with a physical sample following within 7 days.
Standard shipments include the CE Declaration of Conformity, RoHS and REACH statements, and the batch test report. UL Recognition (UL 2464 / UL 20549) is available on request for North American projects — specify this at the quotation stage as it affects the material specification.
Standard configurations ship in 15 working days from order confirmation. Custom-engineered specifications typically require 20–25 working days, depending on compound availability. Rapid sampling for new specifications is 7 days. We will confirm the exact date in writing with your order acknowledgement.
