Submarine cables are wires wrapped with insulating and waterproof materials and laid underwater on the seabed and rivers for power or communication transmission. The role of submarine cables is to provide communication and power transmission for offshore wind power, offshore drilling platforms, island grid interconnection, land island interconnection, and other offshore projects.
Veri submarine power cable company has studied the production of submarine cables for many years. Whether from submarine environment exploration, marine physical investigation, and the world’s large projects’ case study. We also apply sophisticated cable design, manufacturing, and installation methods. The excellent performance and service life of our submarine cables are guaranteed.

Insulated Armored Submarine Cable Electrical Control Signal Cable
With the protection of steel armor around the outside of the cable cores, their insulation, and the inside of the outer jacket, the armored cable is mechanically strong to outside pressure and stretching. It is highly resistant to various kinds of interference to/from its signal and power transmission. The main applications of armored cable are mining, underground, construction, and submarine.
Considering different working conditions and equipment to be applied, VERI’s cable products are highly customized. The high customization level of our cables can make sure that our products can best meet the demands in your pratical application. We welcome you to send a inquiry with specific requirements to our professional sales, and we will provide a technical sheet with cable drawings and detailed specifications to you, and of cource, a competitive quotation will also be send soon after your confirmation of the technical sheet. This can lead to your successful and efficient purchasing.

Submarine Cable Structure Types
In submarine cable development so far, the structure has been design to make a variety of exploration and experimentation, the main structure includes the following types:
1. Impregnated paper-covered submarine cable.
Suitable for not more than 45kV AC and not more than 400kV DC lines. At present, it is only installed at a water depth of 500 m or less.
2. Oil-filled submarine cable.
Use the method of supplemental pregnancy to eliminate the air gap in the cable. When the cable temperature rises, the imp regnant expands, the pressure inside the cable increases, and the demon regnant flows into the oil supply tank. When the cable cools, the pregnant shrinks, the pressure inside the cable decreases, and the pregnant in the oil supply tank flow into the cable again, preventing the generation of air gaps. So it can be used for 110 kV and above lines. Laying in water depths up to 500 m.
3. Inflatable (pressure-assisted) submarine cable.
Using impregnated paper bags of inflatable cable over oil-filled cable is more suitable for the longer submarine cable network. But because of the need to operate under deep water using high air pressure, thus increasing the difficulty of designing the cable and its accessories, generally limited to a water depth of 300 m.
4. “Oil pressure” tube submarine cable.
Only suitable for several kilometers of the cable system, because the very long cable to pull into the pipe, is subject to great mechanical constraints.
5. Extruded insulation (XLPE insulation EPR insulation) cables.
Suitable for up to 200kV AC voltage. Ethylene propylene rubber is more resistant to dendritic phenomena and local leakage than polyethylene, making submarine cables function more effectively.
