Submarine Cable
Submarine Cables’ three main markets for ZMS are offshore oil, transoceanic power transmission, and offshore wind. Marine cables are used in special applications and therefore have more stringent quality requirements. As we at ZMS Power continue to grow and develop, the functional range of specialty cables is also expanding, so you will always find a specialty cable that meets your specific requirements. If there is no special cable that meets your requirements, we can customize cables with special characteristics for your particular application to achieve your specific purpose or task.

Laying and Installation of Submarine Cables
- After arrival at the site the cable should be examined visually to check any exterior damage.
- At site the cable drum should be rolled only in the direction shown on the flange otherwise the cable may become loose & hence difficult to handle.
- The route of the cable should be decided before hand considering the points like transportation of the cable at these points, atmosphere and ground conditions, where joints and terminations will be done, etc.
- While laying up the cable minimum bending radius as required to be strictly maintained.
- If the cable is pulled by pulling eye or winch, utmost care should be taken that tensile stress on the cable is within its limit.
- If the cable is laid in duct or pipe, outer diameter of the duct or pipe should be at least 1.5 times the diameter of the cable.
- Suitable derating factors should be applied as per the environmental & installation conditions while selecting the size of the cable.
- After laying up the cable system must be subject to the DC voltage as mentioned in the table no. 17. The system should be energized after it has withstood this test.
Reasons to Choose ZMS Cables
ZMS Qualification

About Submarine Communication Cables
The types of submarine communication cables can be simply divided into three aspects.
1. Structurally, they are mainly divided into three-core underground submarine cables and single-core underwater submarine cables. Most of the medium- and low-voltage lines use three-core submarine cables, and most of the high-voltage lines use single-core deep-sea cables.
2. Functionally, it is divided into submarine communication cables and submarine power cables. Submarine communication cables are mainly used for communication services, expensive, but have strong confidentiality. Submarine power cables are mainly used for high-power power transmission underwater, equivalent to underground power cables, but the application occasions and laying in different ways.
3. In terms of load type, they are divided into DC submarine cables and AC submarine cables. DC submarine cable is characterized by low-loss, easy-to-realize long-distance power transmission. However, the DC submarine cable application experience is not rich, DC converter station and other supporting construction costs are high. AC submarine cable loss is large, but the operation and maintenance technology is mature, supporting the construction cost is small. Therefore, submarine cable line designers usually need to weigh the technical and economic aspects to maximize the benefits.
