Floating cable and zero-buoyancy cable, the characteristics of the floating cable: light weight, high tensile strength, sea water resistance. Commonly used for power supply, signal transmission or signal control connection of underwater and deep-sea equipment, mainly used for ROV underwater robots, underwater detection, underwater construction, underwater photography, underwater monitoring and other underwater operation machinery and equipment.

      Due to the harsh and dangerous underwater environment and the limited depth of human diving, underwater robots have become an important tool for marine development and its rapid development. Underwater robot cables have become their important basic accessories, so there are special requirements for underwater cables. The underwater optical cable has the characteristics of oil resistance, corrosion resistance, acid and alkali resistance, seawater resistance, hydrolysis resistance, interference resistance, high tensile strength, high safety, bending resistance, tear resistance, etc., and can withstand heavier mechanical external forces. The underwater cable must move back and forth at high speed with the equipment and be collected by the reel to become the main power supply cable for the underwater robot. Because the cable is long and the underwater robot itself is relatively small and light, the cable is required to be as light as possible and the outer diameter as small as possible.
