Zero-Buoyancy Signal Cable, 3 Twisted Pairs / 6 Cores

Buoyancy is a construction result

A cable is neutrally buoyant when the volume of water it displaces weighs the same as the cable itself. Getting there means choosing light insulation and sheath materials, keeping the conductor cross-section as small as the signal needs, and — where extra strength is required — using low-density aramid rather than steel. The result hangs in the water column instead of loading the vehicle's thrusters or arcing on the surface in a current.

Double-layer protection

The inner sheath is a waterproof compound that wraps the pair bundle tightly and keeps water away from the conductors; the outer sheath is a high-strength polyurethane that takes abrasion, oil and seawater attack. Kevlar fibres run along the axis so the cable can be towed and lifted, and the pair screens hold the signal clean against the interference produced by the vehicle's thrusters and lighting circuits.

Applications

This construction is supplied into the following installations. Tell us which one applies and we will confirm the governing requirement.

Customisation

Core count and cross-section, screen arrangement, sheath compound and colour, print legend, length and termination are all built to order. Send the requirement — including the failed OEM part if this is a replacement — and we will propose the construction and confirm the lead time.
