Applications
Cable is chosen by how it is deployed. A tether launched over a sheave, a cable dragged through a sewer, a cord wound on a drum and a cable twisted inside a robot joint fail for completely different reasons — so the construction differs.
ROV & Underwater Intervention
Work-class and observation ROVs run on one line that has to carry power, control, video and sensor data while being launched, towed and recovered. Buoyancy balance and a strength member that isolates the cores are what keep the vehicle flying.
Tethered UAV & Aerostat Systems
Continuous flight means ground-supplied power. Every metre of tether adds weight and voltage drop, so the construction is chosen around current, altitude and wind load rather than around a standard section.
Offshore Wind & Oil and Gas
Salt water, UV, abrasion and continuous movement. Subsea power and control links for turbines, platforms and subsea production equipment are specified for the installation method as much as the electrical duty.
Ocean Observation & Sonar
Sensor arrays stay deployed for months and have to keep the noise floor low. Screened pairs, dedicated fibre units and stable dielectric materials protect the measurement as much as the signal.
Pipeline & Sewer Inspection
Crawlers work in wet, abrasive and chemically active pipe at diameters that leave little room for the cable. Small diameter, high-density jacket and a water-blocked core decide the deployment length.
Elevators & Hoisting
Traveling cables and drum cables operate in one plane, millions of times, inside a shaft or on a drum. Flat construction, flame behaviour and cold flexibility are part of the specification.
Robotics & Motion Control
Drag chains and robot joints load a cable differently: one bends in a defined radius, the other twists. The stranding and jacket compound have to match the motion, or the cable becomes the maintenance interval.
Diving, Aquaculture & Survey
Camera and sensor cables handled by people on deck and in the water: light, flexible, resistant to repeated coiling and to the chemistry of the site.
Specify the duty, then the cable
Most cable problems start as a specification gap rather than a manufacturing defect. Six inputs decide the construction:
