Subsea & Underwater Power Cable
Tinned-copper cores, halogen-free insulation and a PUR outer sheath for permanent immersion.
View constructionShielded Ethernet pairs in a waterproof jacket, for cameras, sensors and subsea instrumentation.
Subsea cameras and sensors do not tolerate packet loss, and a water-ingress path shows up as an intermittent link rather than a clean failure. These cables use tinned-copper Ethernet conductors with individual pair screens plus an overall braid, held at 85 % or better coverage, so the pair is protected against both differential and common-mode interference along the whole run.
Because water travels along a cable far more easily than it crosses a jacket, the waterproof rating depends on the termination as much as the cable. We supply the cable configured for your connector — overmoulded, potted or gland-terminated — and can provide the same construction in a composite body that carries power alongside the data pair so a single subsea run serves both.

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