With the development of deep-sea marine technology, the application of underwater robots has become more and more extensive, mainly in shallow water oceans and high-polluting, complex, and harsh sea areas. Therefore, the underwater robot cable used with the underwater robot equipment becomes particularly important. The zero-buoyancy rov cable was born as a power connection and control of underwater robot equipment, as well as signal transmission and feedback link cable applications.

The zero-buoyancy cable has been tested by the market and practice due to its excellent performance and product advantages. Then, compared with the traditional underwater cable, what design advantages does the zero-buoyancy cable have?

Disadvantages of underwater cables:

1. In order to ensure the insulation of the cable, the number of insulation layers of the cable will be increased, so that the cable will become very heavy;

2. Traditional cables do not have floating performance. When used in underwater operation equipment such as underwater robots, they will continue to sink, which not only causes inconvenience in the operation of underwater equipment but may even cause the joints between the equipment to fall off.

Advantages of zero buoyancy cable:

1. The zero-buoyancy floating cable is designed with a buoyancy structure. The cable is used in underwater equipment. It is dragged and sunk with the equipment's diving operation, effectively avoiding the inconvenience caused by the excessive sinking of traditional underwater cables;

2. It can be designed for power, control, signal transmission and feedback, and comprehensive use of composite cables, which are easy to use and save installation space;

3. Tinned copper mesh + aluminum foil Mylar as the shielding material of the cable, split-screen + total screen/total shield design (single layer or double layer structure design for both sub/total shielding), the cable has excellent anti-interference performance and guarantees The stability and accuracy of underwater signal transmission and feedback signals.

4. The Kevlar fiber is used as the tensile force component of the cable to fill or deteriorate the cable body, and its tensile strength can be customized according to needs.
