According to the sealing method, it can be divided into two types: horizontal and longitudinal. The longitudinal submersible pump cable USES water blocking glue or foam to delay the cable flow inside the cable. Improve the reliability of equipment.

The cable of traditional submersible pump is sealed by water-blocking paste. After curing water-blocking paste at room temperature, the components are closely combined to form a solid whole to achieve water-blocking effect. However, the cable suffers from external factors such as repeated winding, which results in relative displacements and gaps in the surfaces of tightly bonded components. Once the cable breaks, water with strong water pressure will penetrate along the gap.

In recent years, the scale of China's shipbuilding industry has expanded rapidly, the output of vessels has increased significantly, and the types and structures of vessels have been constantly upgraded. It is imperative to improve the localization of China's Marine supporting equipment and realize the leapfrog development of China's Marine supporting equipment.

The ship cable is used as the nerve and blood vessel of the ship. Cables are also directly related to the safety, reliability and advancement of ships. When ordinary cables encounter seawater, they cannot prevent seawater from seeping into other compartments and entering the equipment through the cables. It is not possible to ensure that watertight compartments do not pass through cables and enter the water. At the same time, seawater entering the cable will corrode the cable, causing the entire cable to be scrapped and damage to the precision equipment connected to the cable. So the scientists developed a new cable-submersible pump cable

The advantage of submersible water pump cable is that it provides deep water cable for ships. It can be used in deep water, especially seawater. It has the characteristics of longitudinal waterproof, and seawater will not penetrate into the cable.
