With the improvement of electrification, the application of marine cables is becoming more and more extensive. Common marine cables are the wires used for power and lighting of various ships in various rivers and seas, ships, and offshore oil platforms. cable. Damage to the insulation of marine cabl......

According to whether there is shielding layer, twisted cable is divided into shielded twisted cable (STP) and unshielded twisted cable (UTP).

There is only one conductor in the insulating layer of single core wire. Advantages: strong tensile resistance, not easy to be broken by mold, convenient threading and good stability. Disadvantages: poor heat dissipation, poor softness and poor bending resistance.

The cable core is wound with fine copper wire and serves as a power cable for mobile equipment.

Conductive core: made of high conductivity material (copper or aluminum). According to the requirements of laying conditions on the flexibility of the cable, each wire core may be twisted by a single conductor or multiple conductors.
