70mm² H01N2-D Rubber Welding Cable – CE Compliant for Shipyard & Factory Operations

Cable failure is never just a cable failure. It’s unplanned downtime.
In a shipyard block assembly hall or a factory heavy-bay, a burnt welding lead puts welders out of action and disrupts critical path schedules. The 70mm² H01N2-D rubber cable is built to prevent exactly that. Conforming to the EN 50525-2-81 harmonized standard and carrying a permanent CE mark, it pairs a flexible fine-stranded copper core with a heavy-duty, oil-resistant rubber sheath. The result: lower replacement rates and predictable arc performance, shift after shift.

What Makes This Cable a Practical Asset on the Shop Floor

• Extra-Flexible Class 6 Copper (70mm²) — Thousands of 0.20 mm bare copper strands form the conductor, achieving extreme pliability without sacrificing cross-section. The low resistance limits heat build-up during 400A+ cycles. Arc starts become crisp and consistent. Welders spend less time fighting amperage drift, and energy losses drop to a level that your metered utilities will reflect.

• Polychloroprene Sheath for Mechanical & Chemical Defense — The jacket is a cross-linked elastomer compound, tested for oil resistance and flame retardancy per EN 60332-1-2. Dragging this cable across deck plates, sharp I-beam edges, or concrete floors doesn’t shear it. Occasional contact with cutting fluids and grease doesn’t swell or soften it. That toughness directly extends service intervals, reducing procurement ticket frequency.

• Full H01N2-D Compliance Backed by Batch Testing — No quiet hopes. Every production run undergoes a 1,000V spark test and conductor resistance measurement. The designation H01N2-D is printed at meter intervals: a direct statement of identity for site inspectors. Handover documentation includes a mill test report with traceable bath numbers. There is no ambiguity for your QA department or any third-party surveyor checking a project submittal.

• Temperature Range That Covers Remote & Harsh Sites — The cable functions from -25°C to +85°C at the conductor. Below freezing, the rubber remains pliable enough to reel and unreel without cracking. At continuous high load, it resists the thermal ageing that hardens inferior jackets. One cable standardised across Arctic pipeline work and Middle Eastern site fabrication simplifies your inventory.

• Supply Chain Support: Pre-Terminated Ends & Custom Spools — Standard drums carry 100 m or 250 m. You can also order exact cut lengths with factory-attached copper lugs or DINSE connectors, crimped under calibrated pressure. This removes a secondary labour step from your workshop schedule. It also strips out the variability of field terminations: no loose crimps, no hotspot generation at the connection point.

Technical Specifications & Dimensions

Where the 70mm² H01N2-D Cable Proves Its Durability

• Shipbuilding & Repair Yards — On open decks, salt spray, hydraulic oil, and raw steel edges are constant. The oil-proof rubber jacket prevents insulation breaching that leads to short circuits in rain. Welders maintain a stable return path, even when cables lie in puddled bilge areas.
• Pressure Vessel & Heavy Pipe Fabrication — Work here is often all-position, inside confined shells. The Class-6 copper stays limper than semi-flexible alternatives, reducing shoulder strain for the operator. Reduced operator fatigue cuts the hidden cost of rework on X-ray-critical joints.
• Heavy Machinery Assembly Plants — Fixed-position booms and pendulum drag loops fatigue ordinary cables quickly. The H01N2-D’s dynamic flex rating holds up under repeated bending, so cable replacement cycles sync better with planned maintenance windows rather than emergency call-outs.
• Civil Infrastructure & Piling Sites — Cables run through mud, grit, and vibrating machinery. The tough outer sheath and UV-stable compound (where specified) resist environmental cracking. Power delivery to 500A DC rectifiers remains stable, slab after slab.
• Mining Support & Maintenance Workshops — In confined maintenance bays with grease-laden floors, a flame-retardant, oil-resistant cable is a safety prerequisite. The cable’s compliance to EN 60332-1-2 gives your safety officer the documentation they need without debate.

Frequently Addressed Technical Inquiries

Our team runs 450A pulsed spray transfer on structural sections. Will 70mm² handle the heat in a 40-metre loop?
70mm² copper has a typical DC resistance of 0.272 ohms/km at 20°C. A 40-metre loop (20 metres out, 20 metres back) adds about 11 milliohms of total path resistance. At 450A, that generates roughly 50W of distributed heat across the cable length—well within its 85°C continuous rating. Voltage drop stays under 5V, keeping your power source regulation inside its sweet spot. If you extend beyond 60 metres loop length, we recommend jumping to 95mm² or running parallel returns.

We need third-party surveyor acceptance for an offshore module project. What documentation do you supply with the cable?
Every shipment includes a Shipment-Specific Declaration of Conformity citing the CE directive and EN 50525-2-81. Upon request, we supply a Manufacturing Test Report (MTR) covering: actual cross-section, spark test pass, conductor resistance values, batch material trace, and dimensional check. This package normally satisfies the Marine & Offshore classification societies during component inspection without further lab testing.

Can you ship pre-terminated cables with 35-70 DINSE plugs already moulded for our production cells?
Yes. We offer hydraulic crimping of standard DINSE-type plugs and copper tube lugs at our outgoing quality station. You specify the connector part number, tail length, and polarity colour ring. The connection is then shrunk-sealed with a heavy-wall adhesive-lined boot. No tape, no hot-melt afterthought. For a run of 50+ assemblies, test certificates for each connector pull-test can be included.

Send your required amperage, total loop length, and site environment details. We return a technical proposal with CIF terms, spool configuration, and any termination costs—no generic quotes. Standard lengths ship from regional stock; factory-ready terminations and custom colours require a short lead time agreed upfront.
