Overview
Developed to satisfy rigorous marine and subsea operational requirements, the cable is a heavy-duty multi-conductor subsea umbilical cable engineered to transmit video signals, deliver audio communications, supply power and carry signals for underwater sensors concurrently.
Developed as an enhanced successor to the traditional CDUR05 cable, this upgraded design incorporates a standalone coaxial channel to broaden camera adaptability. A single cable assembly is capable of supporting balanced twisted-pair cameras as well as unbalanced coaxial camera equipment.
This cable is extensively deployed in diver umbilical systems, subsea inspection machinery and mobile underwater monitoring configurations.
Key Construction & Advantages
- Built-in Kevlar fibre tensile reinforcement; ultimate breaking load reaches 1000 kg, with a safe working load capped at 250 kg
- Premium PUR outer sheath, featuring strong resistance against seawater hydrolysis, surface abrasion and ultraviolet radiation
- 14 internal conductors, consisting of two shielded twisted pairs, quad-core wires, power conductors and a dedicated 75Ω coaxial line
- Supports simultaneous functioning of four-wire communication systems, subsea lighting, video transmission and depth sensing devices
- Flexible structural design with refined bending radius, suited for persistent dynamic movement under water
- Continuous manufacturing length can reach 1000 metres; custom cable termination solutions are available on demand
