HUADONG CABLE GROUP
Professional Cables and Wires Manufacturer in China
1. submarine communications cable is a cable laid on the sea bed between land-based stations to carry telecommunication signals across stretches of ocean, which can suit for seabed and sea area ambient condition, ocean physics characteristic and requirements of laying underwater, with waterproof, anti-corrosion, good machine performance and so on.
2. Modern cables are typically about 25 millimetres (0.98 in) in diameter and weigh around 1.4 kilograms per metre (0.4 lb/ft) for the deep-sea sections which comprise the majority of the run, although larger and heavier cables are used for shallow-water sections near shore.
3. The submarine cables made by our company is armoured with high-tensile steel wire and used with technologies of water-proof and corrosion-proof to ensure the superior properties, test are performed in accordance with IEC60055, IEC60502 and methods recommended.
