At present, the shipbuilding industry is still in an ascending stage, and it will show its prominent position in the next ten years. Due to the good momentum of the ship manufacturing industry, many people began to pay attention to the ship industry, but also began to pay attention to its upstream industries, such as power lines.

　　 The power cord plays an extremely important role in ocean navigation or fishing of ships. If there is no good performance, once a failure occurs, then it will be very miserable. Therefore, the ship's power cord must have the following properties:

　　 One, softness and flexibility

　　In the manufacturing of ships, the power cords are not arranged straight together, but arranged by bending. This poses a challenge to softness and flexibility. If there is no good softness and flexibility, then various failures will easily occur. Once these problems occur in ocean voyages, then the ship can only be stopped on the sea. Therefore, when choosing a marine power cord, choose a soft and flexible power cord.

　　 2. High and low temperature resistance

　　 The resistance of the power cord to temperature is very important. The influence of temperature on the power cord is very large, whether it is low temperature or high temperature, if there is no good resistance to high and low temperature, the temperature will accelerate the aging of the power cord, which will cause a series of problems. Only better high and low temperature resistance can ensure the normal operation of ships.

　　 Three, corrosion resistance

　　General marine power cords also require strong corrosion resistance. This is for power cords that are in contact with seawater. Everyone knows that seawater has a relatively strong corrosion resistance. If there is no good corrosion resistance, then all power cords must be replaced after a short voyage.

　　Only by combining high flexibility and flexibility, strong resistance to high and low temperature, and good corrosion resistance can the ship work normally.
