Ocean cable

Ocean cables, specially designed ocean cables, have high wear resistance, high tear resistance, good weather resistance, high elasticity, good thermal aging performance, excellent water resistance, excellent weather resistance, and resistance to microbial invasion.

Performance of ocean cables

(1) Ocean cables have excellent water resistance, which is an essential performance requirement for cable sheaths. The hydrolysis intensifies on the side with increasing temperature. Its Arrhenius curve indicates that the product has good hydrolysis stability. 0N/m is the universally recognized minimum strength requirement in the cable industry. This curve indicates that the strength will only decrease to 20N/mm after soaking in water at 72 ° C for 20000 hours; (2) The weather resistance of ocean cables is generally affected by the exposure to ultraviolet light and sunlight, resulting in product embrittlement and surface discoloration. The mechanical performance has sharply declined. But we can effectively improve the above performance by adding ultraviolet light stabilizers and pigments. Marine cable polyether type sheath products have good resistance to ozone and can meet the requirements of VDE472-805.

Submarine communications cable

Submarine communications cable is a cable wrapped with insulating materials and laid on the seabed for telecommunication transmission. Submarine communications cable includes submarine communication cable and submarine power cable. Modern Submarine communications cable use optical fibers as materials to transmit telephone and Internet signals.

Use of Submarine communications cable

Submarine communication cables are mainly used in long-distance communication networks, usually between long-distance islands, cross sea military facilities, and other important occasions. The laying distance of submarine power cables is much shorter than that of communication cables, mainly used for connecting between land islands, crossing rivers or harbors, and connecting drilling platforms or drilling platforms from land to each other. In general, the application of Submarine communications cable to transmit power is undoubtedly more expensive than Overhead power line of the same length, but it is often more economical than using small and isolated power stations for regional power generation, and has more benefits in offshore areas. In countries with more islands and rivers, this type of cable is widely used.
