■ Technical Background

Underwater engineering, such as in the ocean, is usually carried out in waters of hundreds or even thousands of meters. In addition to the necessary hardware instruments and facilities, this type of operation also requires the use of cables for transmitting power and signal control; the requirements for cables used in this environment are often very harsh, and ordinary cables have the following disadvantages...
On the one hand, since the operation is on the water, in order to ensure the insulation of the cable, the number of insulation layers of the cable will be increased, so the cable will become very heavy;
on the other hand, the cables used in most engineering equipment cannot float in the water. In this way, when the engineering equipment moves forward, the more the cable falls underwater, the more the burden on the mobile engineering equipment is increased, and it is easy to cause the two ends of the cable to fall off; in addition, the cable is submerged in water, which greatly reduces its visibility. When dragging, it is easy to be damaged by organisms or rocks in the water, and the damage cannot be observed in time.
Therefore, there is an urgent need for a cable that can float on the water, has good softness, ideal mechanical strength, and good water-blocking performance for underwater operations. Therefore, our company designs and produces floating cables to meet market demand. Highly flexible, resistant to folding and bending, excellent waterproof performance, and resistant to seawater corrosion. It can be designed and produced to withstand large mechanical external forces. The elastomeric polyurethane material is highly wear-resistant, maintains flexibility at low temperatures, and has stable compressive resistance. It has been proven to be safe and reliable and can be used in a variety of occasions.
