Individually Screened CAT 7A Marine Ethernet Cable
This CAT 7A marine Ethernet cable features individually foil-screened pairs, an additional aluminium-foil wrapping and an overall tinned-copper braid. The multilayer screening system, fine-stranded conductors and low-smoke halogen-free outer sheath support high-frequency data transmission and enhanced electromagnetic compatibility in shipboard networks.
Key Highlights
CAT 7A transmission · Individually foil-screened pairs · Additional aluminium-foil wrapping · Overall tinned-copper braid · Multilayer EMC protection · Marine-oriented construction · 100 Ω characteristic impedance · Low-smoke halogen-free sheath · Asbestos-free material system · Flame-retardant and self-extinguishing · Low-corrosivity combustion gases · EtherCAT and EtherNet/IP compatibility · Optional M12 or RJ45 assemblies · PFAS-free material option
Recommended for demanding CAT 7A Ethernet connections in ships, vessels and marine automation equipment.
Typical applications include:
- High-performance shipboard Ethernet networks
- Bridge and navigation systems
- Vessel automation and monitoring equipment
- Surveillance and video networks
- Passenger information and entertainment systems
- Machinery diagnostics
- Marine control cabinets
- Data links between onboard electronic systems
- EtherCAT and EtherNet/IP networks
- Applications requiring enhanced electromagnetic protection
The cable is suitable for fixed installation and occasional flexible movement. It must not be described as a continuous-flex, torsion, submerged or open-deck cable unless the final construction has been separately tested for that application.
Pre-assembled versions with M12 or RJ45 connectors are available on request.

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.
