In addition, there are many crew members on the ship, whether in peacetime or wartime, crew activities are frequent, and cables and wires are scattered in various cabins, and the cabin space is narrow. Therefore, the insulation performance of cables and wires directly affects the safety of crew members. . In modern ships, the amount of marine cables and wires is very large, which has a great impact on the weight, size and cost of the entire power system. Therefore, the correct selection of marine cables and wires for ships is very important.
