LU-001 CABLE (LU-001 Underwater Ultrathermic Exothermic O₂ Cutting Cable) is manufactured in accordance with NEDU Report 7-84 / NAVSEA S0300-BB-MAN-010 for 300/500 V service over -30 °C to +70 °C. Its 4-layer construction comprises central oxygen passage bore, consumable 6×9 spiral steel wire core and extruded polypropylene outer sheath.

What is the minimum bending radius and operating temperature range for LU-001 CABLE?

The minimum bending radius for LU-001 CABLE is 8 × OD across its continuous operating temperature range of -30 °C to +70 °C, ensuring mechanical and dielectric reliability in subsea, marine and submersible service.

How are the concentric layers of LU-001 CABLE arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Central Oxygen Passage Bore — Coreless hollow center channel delivering Depth + 250–380 psi high-purity oxygen; (02) Consumable 6×9 Spiral Steel Wire Core — 6 strands × 9 wires high-tensile steel acting as conductor & >5,500 °C exothermic fuel; (03) Rust & UV Inhibitor Finish — Rough corrosion-inhibiting treatment over spiral steel wire bundle; (04) Extruded Polypropylene Outer Sheath — Gas-tight UV-inhibited polypropylene sheath (SP-A043 6 mm / SP-A047 9 mm / SP-A044 12 mm).

What factory test certificates are supplied with LU-001 CABLE?

Every production drum of LU-001 CABLE undergoes routine conductor resistance/continuity, high-voltage dielectric and dimensional testing per NEDU Report 7-84 / NAVSEA S0300-BB-MAN-010, and is delivered with an EN 10204 3.1 factory test certificate.
