An underwater robot, also known as a remotely controlled unmanned submersible boat, is a type of extreme work robot that operates underwater. As the cable material of this new underwater robot, the PUR material is easy to use and friendly to the environment. The cable is flexible, wear-resistant, oil-resistant, acid-and-alkaline resistant, tensile-resistant and anti-aging. The floating cable is used as the conductor for all types of submersible motors, wire and cable for deep water cage / pull, and is widely used in various submersible and underwater pumps. connected by electric power from the water to the water. Insulation: high-density polyethylene (HDPE), type: low-voltage conductor material: copper / TC, sheath: thermoplastic elastomer with foam (TPE), cushioning: bulletproof Kevlar wire, Protection layer: Mylar aluminum foil / TC.
