Marine Control Cable — DNV type-approved marine and shipboard cable meeting IEC 60092-350 standards. Flame-retardant halogen-free jacket, armoured and unarmoured variants, 85°C–90°C rated. For marine power, control, data, and VFD drive applications on commercial vessels and offshore platforms.
This Marine Control Cable is manufactured to meet the demanding requirements of marine and offshore electrical systems. Designed in compliance with IEC 60092-350 (marine electrical installations) and IEC 60332-3 (flame propagation resistance), this cable carries DNV type approval for use in commercial shipbuilding, offshore platforms, and floating production systems where regulatory compliance is mandatory.
The halogen-free flame-retardant jacket ensures that in the event of fire, the cable does not contribute to toxic smoke generation — critical for crew safety in enclosed spaces on ships and offshore installations. Armoured and unarmoured variants cover power distribution, motor control, data, VFD drive, and telephone applications across the full range of marine electrical system requirements.

Commercial vessels operating under IMO SOLAS regulations, offshore platforms under national maritime authority rules, and FPSO/FSO units under flag state requirements must use type-approved cables from approved manufacturers. Using standard industrial cables in marine applications constitutes a regulatory non-compliance that can result in class withdrawal, port state detention, and insurance invalidation.
Standard PVC cables release hydrogen chloride gas (HCl) and dense black smoke when burning. In an enclosed ship compartment, HCl concentrations become incapacitating within minutes and are corrosive to electronics and metal structures. Halogen-free cables produce only water vapour, carbon dioxide, and minimal smoke — critical seconds that can determine crew survival outcomes.
Individual cable flame tests (IEC 60332-1) are not sufficient for marine installation cables routed in multi-cable trays and trunking. IEC 60332-3 tests bundles of cables — matching real installation conditions. Cables that pass individual flame tests can still propagate fire along cable ways in bundles. DNV type approval requires bundle flame test compliance only.
Standard control cables used on VFD motor drives conduct high-frequency switching noise (1–30 MHz) back through the vessel's earthing system, causing interference in navigation electronics, radio, and alarm systems. Armoured and screened marine VFD cables provide a dedicated low-impedance return path for drive switching currents, isolating the vessel's electrical environment.

Marine cables must be installed in IEC 61084 compliant cable trays or conduit systems, supported at intervals not exceeding 300 mm for horizontal runs and 250 mm for vertical runs. Cable bundles in marine cable ways must not exceed the derating factors specified in IEC 60092-352 — typically a 0.85 factor for 4–6 cable layers and 0.75 for larger bundles.
All cable penetrations through watertight bulkheads, fire-rated decks, and hazardous area boundaries must be sealed with class-approved transit fittings. The gas block cable construction prevents gas migration along the cable core, but bulkhead penetrations require separate transits rated for the bulkhead's A-class or B-class fire rating.
Marine cables in engine rooms and high-vibration areas should be inspected annually for chafing at support points, jacket cracking from thermal cycling, and connector integrity at switchboard terminations. Replace any section showing jacket damage, core exposure, or green corrosion at conductor terminations. Keep inspection records as required by class society survey requirements.
Provide your vessel type, applicable class society, cable function (power/control/data/VFD), conductor size, and required standard — we supply DNV type-approved marine cable with full compliance documentation.
