Halogen-Free Twisted-Pair Screened Marine Data Cable 350 V
This halogen-free marine data cable uses twisted-pair construction and an overall tinned copper screen to support reliable signal transmission with reduced crosstalk and electromagnetic interference. Its flexible, compact design is suitable for protected marine instrumentation and control wiring.
Key Highlights
Twisted-pair signal construction · Overall copper braid · Good EMC protection · Improved crosstalk attenuation · Halogen-free SHF1 sheath · Flexible tinned copper conductors · Low smoke density · Flame-retardant and self-extinguishing · Non-corrosive combustion gases · Suitable for marine automation · RoHS-compatible
Designed for paired signal, measurement and communication circuits aboard ships where EMC performance and crosstalk attenuation are important.
Typical applications include:
- Marine automation systems
- Instrumentation and monitoring equipment
- Paired sensor and actuator circuits
- Communication and low-level signal systems
- Navigation and control equipment
- EMC-sensitive wiring above or below deck
The cable should be installed with mechanical protection and should not remain in permanent contact with oils or fuels unless a suitable sheath is specified.

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.
Your information is used only to prepare your quotation and is never shared with third parties.
