Screened Twisted-Pair Continuous-Flex PVC Data Cable 350 V
This screened twisted-pair PVC data cable is designed for continuous movement in drag chains and automated machinery. Pair-twisted conductors support stable signal transmission and reduced crosstalk, while the overall tinned-copper braid provides protection against electromagnetic interference.
Key Highlights
Twisted-pair construction · Overall tinned-copper braid · Good EMC characteristics · Reduced crosstalk · Continuous-flex design · Maximum operating voltage 350 V · Small bending radius · Colored core identification · Reinforced PVC sheath · Flame-retardant and self-extinguishing · Suitable for cable drag chains · Wide range of pair counts · Customized transmission designs available
Recommended for flexible data, measurement and control-signal transmission in moving machinery and electrically noisy industrial environments.
Typical applications include:
- Cable drag chains and energy chains
- Industrial sensors and measuring devices
- Automated assembly lines
- Packaging and woodworking machinery
- Machine tools
- Encoder and feedback circuits
- Factory automation systems
- Low-voltage communication and control equipment
The cable is designed primarily for continuous bending. Continuous torsional use requires an application-specific torsion-rated design.

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.
SEND US YOUR
SPECIFICATION
Tell us your core count, cross-section, and application — our engineering team will confirm the right configuration and send pricing within one working day.
