This heavy-duty industrial cable is engineered for high-voltage power transmission and integrated data communication in demanding mobile environments. Designed for extreme mechanical loads, it is the ideal solution for large-scale machinery requiring frequent reeling and unreeling operations.The composite cable features a robust multi-core design paired with a 12-core fiber optic unit. This integration allows for high-capacity power delivery and real-time data transmission within a single, highly durable jacket.
▍Key Technical Specifications

▍Applications
Designed for the connection of large mobile equipment under high mechanical stress:
Port and Terminal Equipment: Gantry cranes and loading bridges.
Mining & Excavation: Large-scale excavators and spreaders.
Construction & Infrastructure: Mobile machinery and heavy-duty building equipment.
Hazardous Areas: Suitable for environments with a high risk of explosion.
Q1: Can the cable be submerged in saltwater?
A: Yes, the combination of PUR sheath (water absorption ≤0.5% after 24 hours) and interlocked steel armor provides watertight protection, allowing temporary submersion (up to 72 hours) during high tides or storm surges.
Q2: What is the cable’s temperature range?
A: It operates reliably between -40°C (polar ports) and +100°C (engine rooms of port machinery), maintaining flexibility and insulation performance across extreme conditions.
Q3: Is the cable resistant to oils and fuels?
A: Yes, the PUR sheath is highly resistant to mineral oils, hydraulic fluids, diesel, and gasoline, with no measurable swelling after 1,000 hours of immersion in ASTM D471 tests.
Q4: Does the cable require special termination?
A: Standard crimp or solder terminations with heat-shrink boots (IP68-rated) are recommended. We also offer factory-installed connectors (e.g., LAPP SKINTOP®) for plug-and-play installation.
Q5: What certifications does the cable hold?
A: It is CE-certified for safety, RoHS-compliant for environmental protection, and meets the requirements of the International Maritime Organization (IMO) for shipboard cables.
