The power cable is usually carried out in water areas of hundreds or even thousands of meters. The requirements for cables used in this environment are often very strict. Generally, the insulation of ordinary cables is often increased by the number of insulation layers of the cable, which makes the cable very heavy. During the process of moving engineering equipment forward, the more cables fall underwater, the more burden the mobile engineering equipment has, and it is easy to greatly reduce its visibility, When dragging, it is easy to be damaged by organisms or rocks in the water, and the country cannot observe the damage in a timely manner. Therefore, good cables can be used for navigating in harsh underwater environments, with limited diving depth for humans. Underwater robots have become an important tool for developing the ocean and their rapid development. Underwater robot cables have become a series of special requirements for underwater cables, such as tear resistance. Due to the long length of the cable and the small and lightweight underwater machine, it is required that the cable should also be lighter. This type of cable used in China is relatively thick and stable in signal transmission. It can withstand 100KG tensile force. 6. It can be customized with multi-core umbilical wrapped vulcanized waterproof joints. 2. It is acid, alkali, corrosion resistant, and has a protective sleeve with a temperature of -20~120 ° C. Produce optoelectronic hybrid cables, 485 communication cables, CAN6, customizable zero float sealed connectors, optoelectronic slip rings, electric manual pay-off winches, and other accessories
