Specialty cable engineering — Kunshan, China

Cables engineered for depth, motion and time.

Neutrally buoyant umbilicals, tethered aerial power lines, watertight optoelectric links and continuous-flex industrial cable — designed around the working condition, not a catalogue section.

What we make

One engineering team, three environments.

PAIDE builds cable for places where a standard product stops being adequate: below the surface, in the air on a tether, and inside machines that never stop moving.

The same design logic runs through all of them. Work out what the cable has to survive — pressure, tension, cycles, temperature, chemistry — then choose conductor, insulation, screen, strength member and jacket together, because each one constrains the others. Founded in Kunshan, Jiangsu, and supplying overseas since the export business began.

02 — Capability

From requirement to tested assembly.

Design, cabling, extrusion, screening, overmoulding and test under one roof — which is what allows a construction to be changed for one project.

01

Construction design

Each cable starts from the working condition: depth, pressure, tensile load, bend radius, cycle count, temperature and the connector at each end. Conductors, insulation, screening, strength member and jacket are then selected together, because they constrain each other.

02

Conductor and cabling

Bundled and concentric stranding, lay length control and unit grouping. Power, signal and fibre units are kept in defined positions in the core so crosstalk, stripping and termination stay predictable.

03

Screening and strength members

Aluminium foil with drain wire, tinned copper braid at specified coverage, and aramid or HMPE strength members sized to the load case. The strength path is kept mechanically separate from the electrical cores.

04

Extrusion and jacketing

TPU, PUR, PE, PVC, FEP and silicone jackets, including foamed layers for buoyancy. Wall thickness and concentricity are controlled because they set both the water resistance and the finished diameter.

03 — Series

Where the cable has to work.

03 families

Marine & Subsea

Cable systems that live in salt water: power, control, signal and fibre for vehicles, sensors and structures below the surface.

01 family

Tethered Systems

Lightweight hybrid tethers for drones, aerostats and elevated platforms: power up, data down, over a single load-bearing line.

07 families

Industrial Automation

Continuous-flex cables for machines that move: drag chains, robot joints, hoists, elevators and inspection robots.

03 families

Accessories & Connectors

The parts that decide whether a cable survives the installation: grips, lacing, wet-mate connectors and terminations.

05 — Applications

Specified by the installation.

A cable is chosen by how it is deployed: launched over a sheave, dragged through a pipe, wound on a drum, or twisted in a joint.

06 — Questions we get asked

Technical, not commercial.

How do I choose between a neutrally buoyant and a standard underwater cable?
It depends on where the cable has to sit in the water column. A neutrally buoyant construction is used when the cable must follow the vehicle or the structure without loading it — ROV tethers, towed arrays, dive support. Where the cable is fixed, armoured or laid on the seabed, a standard water-blocked power construction is simpler and carries more copper per millimetre. Density is a design output, so tell us the working depth and the acceptable in-water weight and the construction follows from that.
What determines the tensile rating of an underwater cable?
The strength member, not the conductor. Aramid or HMPE fibres are sized to the specified working and breaking load and terminated at both ends, so the electrical cores and any fibre unit carry no tension. The jacket and the connector strain relief only have to transfer load into the strength member. If a customer gives a required breaking force, we size the member to it with a margin for terminations.
Can power, signal and fibre share one cable?
Yes, and it is usually the reason a hybrid is specified: one cable means one connector set, one penetration and one handling operation. Power cores, twisted signal pairs and single-mode or multi-mode fibre units are laid in separate positions in the core, with individual screening where the signal requires it.
What is the difference between a drag-chain cable and a robot-joint cable?
The motion. A drag-chain cable bends repeatedly in a defined radius in one plane, so fine-wire stranding and a low-friction jacket are the priority. A robot joint twists the cable in both directions, so the lay direction, strand construction and jacket compound are chosen for torsion. Using one in the other application shortens life dramatically.

Talk to engineering

Send the working condition, not a part number.

Depth, load, bend radius, cycle count, temperature, connector type at each end. With those five inputs we can propose a construction sheet within two working days.
