CDUR01 Umbilical Cable for Underwater Video, Data and Power
CDUR01 umbilical cable is a multipurpose underwater umbilical cable designed to combine low-voltage power, video/data signal paths and mechanical reinforcement in one compact cable. It is intended for commercial diving, CCTV inspection systems and tow-cable applications where the cable must be handled in water, pulled under load and routed through deployment equipment.
The construction includes two 0.8 mm² power conductors, four 0.34 mm² power conductors and three 2 × 0.2 mm² twisted shielded pairs. A Vectran fibre braid provides strength reinforcement, while the orange PUR jacket gives the cable an abrasion-resistant protective outer layer suitable for underwater handling.
This cable should be selected by both electrical and mechanical criteria. Working voltage, conductor resistance, signal pair requirements, water weight, bend radius, working load, breaking strength, length and termination method all affect whether the cable fits the project.
Key Engineering Features
- Hybrid power and data construction: The cable combines power conductors and twisted shielded pairs, reducing the need to manage separate power and signal cables in underwater deployment.
- Vectran braid strength member: The Vectran fibre braid provides mechanical reinforcement and supports a listed 1500 kg breaking strength for demanding handling and tow-cable applications.
- Orange PUR outer jacket: PUR is commonly selected for abrasion resistance and handling durability, while orange colour improves visibility on deck and during deployment.
- Defined underwater weight: The supplied data lists 155 kg/km in air, 38 kg/km in fresh water and 35 kg/km in sea water, which helps engineers estimate handling load, buoyancy behavior and deployment tension.
- Controlled bending limits: Static bending radius is 61 mm and dynamic bending radius is 122 mm. These limits should be checked against sheaves, reels, fairleads and cable guides.
- Long cable capability: Lengths are available up to 1000 m, but voltage drop, conductor resistance and signal performance should be reviewed for long runs.
- Custom termination support: The cable can be ordered with custom termination, making connector type, potting, strain relief and pin assignment important RFQ details.

Selection Notes for Buyers
Start by confirming the electrical functions. The cable includes several conductor sizes and twisted shielded pairs, so the pinout, signal type, voltage drop and current per conductor must be mapped before choosing a termination.
For long runs up to 1000 m, check conductor resistance and voltage drop carefully. A 250 V working voltage does not automatically guarantee that connected equipment will receive the required voltage at maximum length.
Mechanical selection should include breaking strength, maximum working load, water weight, sheave diameter, winch or reel geometry, dynamic bending radius and expected pulling profile. The maximum working load is 375 kg, while the breaking strength is 1500 kg; these two values should not be confused during safety-factor calculations.
For commercial diving and CCTV systems, specify whether the cable will be used in fresh water or sea water, expected depth, deployment method, connector type, strain relief, potting method, termination drawing and required test documentation.
