● Application scope of Deru ROV underwater cable:

Equipment for shallow sea and deep sea survey operations.

Mainly used underwater cable-operated remotely operated submersible equipment

Underwater robots, underwater equipment power supply, cable equipment signal control, etc.

It is suitable for high watertight, twist-resistant multi-core comprehensive cables in the fields of ships, offshore oil platforms, deep sea resource exploration and other fields. It can also be used for various types of submersible motor lead wires, telescopic/drag wires and cables in deep water, and diving Pumps and various underwater working electrical appliances are connected to the power supply from underwater to above water.

● Technical background of Deru ROV underwater cable:

Underwater operations, such as in the ocean, are usually carried out in waters of hundreds of meters or even kilometers. In addition to the necessary hardware and equipment, this kind of operation also requires the use of cables for transmitting power and signal control; for this kind of environment The requirements for cables used under water are often very demanding. Ordinary cables have the following shortcomings. On the one hand, because they are operated on water, the number of insulation layers of the cable is often increased to ensure the insulation of the cable, so that the cable will become very heavy; On the one hand, most of the cables used in engineering equipment cannot float in the water. In this way, when the engineering equipment moves forward, the more the cables fall underwater, the more the burden of moving the engineering equipment increases, and it is easy to cause damage to the cables. Both ends fell off; furthermore, the visibility of the cable is greatly reduced when it is submerged in water. It is easily damaged by creatures or rocks in the water when being dragged, and the damage cannot be observed in time. Therefore, there is an urgent need for a cable that can Cables that float on water, have good flexibility, ideal mechanical strength, and good water-blocking properties are used for underwater operations. Therefore, our company designs and produces zero-buoyancy floating cables to meet market demand.
