Subsea Electrical Cable
Subsea Electrical Cables are electrical wires wrapped in insulating and waterproof materials and laid underwater on the seabed and in rivers for the transmission of electricity or communications. Submarine cables are used for offshore wind power, offshore drilling platforms, island grid interconnections, land island interconnections and other offshore projects to provide communication and power transmission.
VERI Submarine Power Cables has been researching the production of subsea electric cables for many years. Whether it is from environmental exploration of the seabed, marine physical surveys or case studies of large projects around the world. We also utilize advanced cable design, manufacturing and installation methods. Our subsea electric cables are guaranteed for excellent water resistance and longevity.
Subsea Electrical Cable Products Model
XLPE Insulated Submarine Cable
XLPE insulated subsea power cable has several advantages over paper-insulated and PVC-insulated cable. It has high electric strength, mechanical strength, high-aging resistance, environmental metal stress resisting anti-chemical cross, and it is a simple construction, using convenient and higher operating of long term temperature. It can be laid with no drop restriction.
Applications: These subsea power cables are suitable for fixed installations in the offshore range, such as distribution networks or industrial installations. Such as plant engineering, industrial machinery, heating and air conditioning systems, power stations, etc.

Armored Signal Subsea Electrical Cable
Armored Subsea Electrical Cables are protected by steel armor on the outside of the cable core, the insulation and the inside of the outer sheath, and therefore have strong mechanical strength against external pressure and stretching. And also can also fight against the corrosion of various acidic substances on the seabed, stronger water-blocking properties. It has a strong resistance to all kinds of interference in signal and power transmission. Armored submarine cables of this construction are mainly used in mining, underground, construction and submarine in the offshore range.

Subsea Composite Cable
Subsea Composite Cable is a major transmission cable that carries power below the water’s surface. It is also possible to use submarine power cables beneath the water. VERI Cable has a series of advanced high-voltage cable and submarine cable production equipment capable of manufacturing onshore and submarine power cables of 500KV and below.
Types & Purposes
– For offshore wind farm
– Export cable to transport the total generated power from the offshore substation to the onshore substation
– For interconnecting grids of countries
– Power supply from the mainland to isolated islands

We Also Produce the Following Submarine Electric Cable
In submarine electric cable development so far, the structure has been designed 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 flows 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 EPR 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.
Prospects Of VERI Subsea Power Cables
The complexity of the marine environment of the submarine cable project put forward high requirements, underwater cable engineering is a recognized problem in the world, construction difficulties, and high maintenance costs. And it was only a few companies in the world can lay and commission submarine high-voltage cables. The development of the subsea power cable market has been greatly restricted. More issues, but more solutions to the problem.
