TPE Underwater zero buoyancy cable Wire Rov Floating Cable Waterproof For Submarine

Zero buoyancy electricity
Zero buoyancy electricity avoids sinking due to its own weight, which can cause the burden of various underwater operations. Shen adopts a special structure, and Tsuji electricity floats on the surface of the water and can be used as a telescopic towing device for various diving operations. Zero buoyancy is used for underwater power, signal transmission or signal control, mainly for underwater robots, underwater detection, underwater construction, underwater imaging, underwater monitoring and other underwater operations machinery.

Product characteristics

Zero buoyancy turtle has good characteristics such as oil resistance, corrosion resistance, acid and alkali resistance, seawater resistance, hydrolysis resistance, anti thousand resistance, high tensile strength, anti corner biting, high safety, material reduction, and cost reduction.
Application scope: Country

Zero buoyancy avoids sinking due to the weight of Shen himself, which can cause damage to various underwater operations. Shen adopts a special structure where Tsuji Shen floats on the surface of the water and can be extended and retracted for various diving operations. Commonly used for underwater power, signal transmission or signal control communication, mainly for underwater robots, underwater detection, underwater construction, underwater imaging, underwater monitoring and other underwater operations machinery.
