Watertight Cables
It is divided into longitudinal watertight cables and transverse watertight cables, waterproof power cables, waterproofcoaXial cables, waterproof signal cables, waterproof controlcables, waterproof optical cable cables, and waterproof compositecables.
In the field of underwater detection and robotics, underwater robots, underwater cameras, underwater thrusters, shiptowed sonar, torpedoes and other underwater equipment are used to achieve electrical connections and signal transmissionbetween devices.
