Construction

The physical architecture of this marine cable is designed for maximum resilience and signal integrity. The cross-linked polyethylene (XLPE) insulation offers a clean, smooth finish that actively resists moisture penetration, while the galvanized steel or tinned copper wire braiding provides a rigid, protective armor against physical abrasion and mechanical impact. The common shield, utilizing aluminum foil tape paired with a tinned copper drain wire, effectively mitigates electromagnetic interference, ensuring pristine signal clarity for critical control systems. Every layer is precisely extruded and tightly bound, resulting in a perfectly concentric cable that is remarkably easy to strip, splice, and terminate during on-site installation, significantly reducing labor time in confined shipboard spaces.

Standards applied

Compliance is non-negotiable in maritime engineering. This product strictly adheres to recognized international frameworks, ensuring your vessels and offshore platforms pass rigorous safety inspections without delay. The materials undergo severe testing protocols, emitting virtually no toxic halogens or dense smoke when exposed to extreme heat. This characteristic is vital for personnel safety in enclosed shipboard spaces, maintaining clear visibility for evacuation routes. By meeting these exact criteria, the cable significantly reduces liability risks and enhances the overall safety profile of your marine assets, giving project managers complete peace of mind.

Cores identification

To facilitate rapid and error-free installation in complex wiring panels, the core identification system is designed for maximum visual clarity. The vibrant, high-contrast colors—such as the distinct red, white, black, and blue—are deeply embedded directly into the insulation material, preventing fading even after years of exposure to harsh industrial environments. For multi-pair, multi-triad, or multi-quad configurations, the crisp, highly legible printed numbers on each core eliminate guesswork for electricians. This meticulous attention to visual coding drastically reduces labor hours during initial commissioning and vastly simplifies future maintenance or troubleshooting procedures.

Outer sheath color

The standard black outer sheath provides a professional appearance while offering exceptional UV and weather resistance. The matte finish of the polyolefin or PVC material feels smooth to the touch, specifically formulated to resist the accumulation of industrial grime, oil spills, and salt deposits common on vessel decks. Beyond the standard black, we understand that complex wiring architectures often require visual segregation. Should your specific project require color-coded routing for different operational zones—such as distinguishing critical safety circuits from general data lines—we readily accommodate custom color requests. This flexibility ensures your cabling infrastructure aligns perfectly with internal safety protocols and international maritime organizational standards.

Main characteristics：

Engineered to perform flawlessly across a wide thermal spectrum, this low voltage cable maintains its structural integrity and electrical properties whether exposed to freezing offshore winds or the intense ambient heat of a ship's engine room. The insulation materials remain highly flexible in sub-zero conditions, preventing hazardous micro-cracking during installation, while safely withstanding continuous high-temperature operations up to 90℃. Furthermore, the impressive smoke density performance ensures that, in the unlikely event of a fire, visibility is maintained for safe personnel evacuation and rapid emergency response, proving its worth as a critical safety component.

Operating temperature：-15℃(^1*-60℃)～+90℃

Test voltage：1.5kV/5min

¹Smoke density of completed cable：≥60%

Application

This instrumentation and control cable serves as the vital nervous system of modern maritime automation. It is extensively utilized in the critical control systems of commercial vessels, naval ships, and offshore oil and gas platforms. From monitoring propulsion metrics to integrating complex navigation and safety alarms, the cable ensures that vital data flows without interruption. Its heavy-duty construction resists the corrosive effects of salt spray and the constant, low-frequency vibrations generated by heavy marine machinery. By choosing this cable, project managers ensure a resilient infrastructure that minimizes downtime and maintenance costs in some of the world's most unforgiving operational environments.

The cable is mainly intended for the control system of shipboard and offshore buildings, as well as other related industries.
