Technical Specs & Approval

Technical Specifications: Marine Power Cables

Hangzhou Star Marine Technology Co. Ltd. designs and manufactures marine power cables to stringent international standards, ensuring operational safety and longevity in harsh maritime environments. Our cables comply with IEC 60092-350 series, ICEA P-IC-19-81A, and ABS/DNV-GL certification requirements. Critical design parameters prioritize material integrity, environmental resilience, and electrical performance. Conductor materials utilize high-purity aluminum alloy (1350-O temper) as standard for optimal weight-to-conductivity ratio and corrosion resistance, with galvanized steel armored variants available for high-mechanical-stress applications such as thruster systems or subsea installations. Insulation employs cross-linked polyethylene (XLPE) rated for 90°C continuous operation, providing superior thermal stability and dielectric strength compared to traditional EPR compounds.

Watertight integrity is achieved through triple-layer extrusion technology: a seamless XLPE insulation layer, followed by a longitudinally welded aluminum-polyester laminate moisture barrier, and a final polyurethane (PUR) or halogen-free flame-retardant (HFFR) outer sheath. This construction ensures IP68/IP69K ratings per IEC 60529, withstanding 10 bar pressure at 3 meters depth for 72 hours without ingress. Dimensional tolerances strictly adhere to IEC 60092-353, with conductor cross-sections ranging from 1.5 mm² to 630 mm². Outer diameters include ±0.5 mm allowances for sheath thickness consistency, critical for conduit compatibility and termination reliability. Minimum bending radii are defined at 6× outer diameter during installation and 4× during service to prevent insulation damage. Operating temperature spans -40°C to +90°C (dry) and -25°C to +60°C (submerged), with short-circuit resilience up to 250°C for 5 seconds.

The following table summarizes core technical parameters for standard marine power cable configurations:

All cables undergo 100% factory testing per IEC 60885, including partial discharge verification (<5 pC at 1.7U₀) and impulse withstand (125 kV peak for 1.8/3 kV class). Dimensional consistency is validated via laser micrometry, ensuring compatibility with international glanding systems. Hangzhou Star’s marine power cables are engineered to mitigate risks of hydrolysis, abrasion, and electromagnetic interference in propulsion, distribution, and auxiliary systems. Compliance documentation, including material traceability certificates and type test reports, is supplied with every shipment to facilitate seamless regulatory approval during vessel commissioning.

Packaging & Logistics

Marine Power Cable Packaging and Logistics Protocol

Proper packaging and logistics execution are critical for preserving the integrity of marine power cables during international transit. At Hangzhou Star Marine Technology, we adhere strictly to IMO and IEC standards to prevent mechanical damage, moisture ingress, and corrosion. All shipments originate from our certified facilities in Zhejiang Province, with primary export via Ningbo Port (major deep-water hub) and Shanghai Port (integrated multimodal connectivity), ensuring optimal routing for global destinations.

Wooden export cases form the foundation of our cable packaging system, constructed exclusively from ISPM 15-compliant materials. These cases undergo mandatory heat treatment (HT) to 56°C for a minimum of 30 minutes, eliminating pest risks per international phytosanitary regulations. Each case bears the official ISPM 15 mark, including country code (CN), producer code, and HT certification symbol. Internal bracing uses kiln-dried softwood with moisture content below 20%, while cable drums are secured with marine-grade polypropylene strapping and vibration-dampening rubber inserts. This methodology prevents axial shifting and conductor deformation during ocean freight.

For high-tensile or extra-heavy-duty cable reels, we deploy galvanized steel pallets with welded structural frames. These pallets feature non-slip epoxy coatings and integrated lifting lugs conforming to ISO 18186 standards. Steel palletization eliminates wood-related moisture variables and supports stacking up to 4.5 meters in containerized holds. Both packaging methods include desiccant packs (minimum 50g/m³) and humidity indicator cards within sealed vapor barriers.

The following table summarizes key packaging specifications:

Logistics coordination begins with pre-shipment verification of all export documentation, including phytosanitary certificates for wooden cases, EUR.1 movement certificates for EU destinations, and detailed packing lists referencing HS Code 8544.49.00. Ningbo Port’s dedicated roll-on/roll-off (RoRo) terminals facilitate efficient loading of oversized reels, while Shanghai’s automated container yards minimize handling delays. All shipments include real-time GPS tracking and temperature/humidity loggers, with data accessible via our client portal. Pre-embarkation inspections by SGS or Bureau Veritas are standard for contracts exceeding USD 50,000.

We enforce a 72-hour climate stabilization period in our 18–22°C warehouse prior to loading, preventing condensation in tropical routes. Container desiccant systems (minimum 1.5kg/TEU) are deployed per IMO MSC/Circ.1073 guidelines. This integrated approach ensures marine power cables arrive at destination ports—whether Rotterdam, Singapore, or Houston—in factory-fresh condition, ready for immediate vessel integration.
