Subsea & Underwater Power Cable

Why tinned copper

Plain copper is the first thing to fail in a marine environment: chloride ions attack the conductor and the resulting oxide raises resistance until the joint overheats. Every Suoqi seawater-resistant power cable is built on class 5 tinned copper, which keeps the strands individually protected even where the sheath is cut or damaged, and stays flexible enough for repeated handling and coiling on deck.

Construction and options

Conductors are laid up with a short pitch and a sliding layer so the cores move against each other rather than abrading, then wrapped with a hydrolysis-stable insulation and a double-layer PUR sheath. We build the cable to the installation instead of the stock list: core count and cross-section, aramid tensile element for towing and lifting duty, tinned-copper braid or individually screened pairs for data, plus the sheath colour and outer diameter your gland or reel requires.

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.
