Submarine Cable

Submarine Cable

Veri Cable was specialized in submarine power cable, is suitable for telecommunications or power transmission between countries or regions. We manufactured high-quality submarine cables with different voltages. In addition to our standard marine cable range, we support designing some special cables for specific project applications. Veri Cable is a worldwide cable manufacturer, such as overhead electric cable, control cable, type of armored cables, and so on. 

Submarine power cables are mainly used for underwater transmission of high-power electrical energy. But the application occasions and laying methods are different. And submarine power cables’ laying distance is much shorter than communication cables. Generally, for transmit electrical energy, the use of submarine cables are undoubtedly more expensive than overhead cables for the same length. But it is often more economical than using small power stations for regional power generation. And it has more benefits in offshore areas. For some countries with many islands and rivers, these cables are popular. Veri submarine power cables are manufactured as VDE, IEC, and ICEA or according to customers’ design and standards.

Types of Veri Submarine Cable

MV submarine cable

XLPE Insulated AC Medium Voltage Submarine Power Cable

These submarine power cables are used for power transmission to offshore islands, oil platforms, or cross-rivers and lakes. But the laying of submarine cables does not require digging tunnels or supporting them with brackets, and low investment or fast construction.

MV Submarine Cable

APPLICATION​

The core of the submarine power cable is covered with a PE outer sheath. After the single steel armor, the cable is finally completed with an outer sheath. So it is mainly for all marine environment conditions,  such as muddy, dry, wet, or oily conditions meeting the requirements. The range of voltage is 6/10(12)kV,12/20(24)kV, 18/30(36)kV, and so on.

HV submarine power cable

XLPE Insulated DC High-Voltage Submarine Cable

High-voltage submarine cable is used for high-voltage power transmission. Most of the submarine power cables are on the seabed at a certain depth, and they are not damage the natural environment, such as wind and waves. The human production activities has interfered with them. Therefore, the cables are safe and stable, with strong anti-interference ability and good confidentiality.

HV submarine cable

APPLICATION​

As a high-voltage power transmission cable, is major for carrying electric power below the surface of the water. The range of voltage is 127/220(245)kV, 160/275(300)kV, 200/345(362)kV, 230/400(420)kV, and so on.

The Laying Method of Submarine Cables

Veri Cable submarine cable laying mainly includes three stages: cable routing survey and cleaning, submarine cable laying, and burial protection. When laying the cable, it is necessary to control the water entry angle. And the laying tension of the cable by controlling the sailing speed.

When laying in the shoal section, the cable-laying ship stops 4.5 kilometers at a distance from the coast. And the tractor was pulled on the shore. The submarine cable is allowed to sink by a floating bag. Underwater remote control vehicles continuously monitor, and adjust to control the forward. Then rocks to avoid damage to the submarine cable.

In the final stage of construction, the main purpose is to protect the submarine cables by deep burial. And reduce the impact of the complex marine environment. Veri cable company supply best quality cables with various constructions and voltage ratings.
