With the economic development, the development of my country's ship industry has entered a period of rapid development. At present, the industries that use the most ships are the transportation industry and fishery. People began to pay attention to the manufacture of ships, and gradually began to notice a small component, that is, the power cord.

　　The power of ships is all transformed by electric energy, not just relying solely on manpower to glide as before. So what standards should the current marine power cord meet?

　　 First, choose based on the shielding effect. Marine power cords must be shielded from the conduction and radiation of high-frequency and low-frequency electrical noise, so as to provide signal protection. Due to different environments, it is difficult to determine the information to be blocked. However, the power cord with shielding function generally has a woven structure with three layers of thin metal foil. It can ensure the elimination of unnecessary signals and protect the required signals.

　　The second is to choose a power cord with good temperature resistance. The temperature of the ocean changes according to the environment. If you want to go to cold places such as the Arctic Ocean, the power cord must have good low temperature resistance and can withstand the adverse effects of low temperature. At the same time, the temperature faced by the power cord on the ship's surface and the power cord under the water is also different. Therefore, the choice of marine power cords generally must have better high and low temperature resistance.

　　 In the end, the waterproof is better. Water resistance not only refers to the power cord on the bottom of the ship, but also refers to the power cord on the ship. Ocean voyages are faced with sea water, which requires good waterproof performance. Otherwise, various electric shock accidents will occur once it encounters water.

　　Only power cords that meet these three properties can be adopted by the shipping industry.
