Qifan Cable-Make pioneering efforts and forge ahead!
Steel Wire Armoured (SWA): The cable is equipped with a steel wire armoring. The steel wires provide mechanical protection to the cable, enhancing its resistance to external forces such as pressure, tension, and impact.
Submarine/Undersea Power Cable: This cable is specifically designed for undersea or submarine applications. It is intended to be installed underwater, typically in subsea environments like ocean floors or lakes, to transmit electrical power over long distances.
