Marine cable, the main use in the ship or offshore construction of power, signal transmission Due to the use of harsher environmental conditions, the cable is required to be safe and reliable, long life, small size, light weight, and has excellent temperature resistance, fire resistance, flame retardant, oil resistant, moisture resistant, seawater resistant, excellent electrical and mechanical properties and other requirements. Marine power cable is a kind of marine cable. Commonly used standards: IEC 60092 series, GB/T 9331 series Similar to the main classification of wire and cable, marine cables can be divided into marine power cables (including rated voltage frequency AC 1kV and below low-voltage power cables and rated voltage frequency AC 3 ~ 15kV medium voltage power cables), marine control cables, marine communication cables, marine signal cables and marine RF cables according to the scope of use. Cable connection equipment purposes, for power, lighting and signal transmission, etc. Cable laying position requirements whether long-term immersion in water, low temperature and the requirements of whether with shielding, etc. In addition, in the working conditions, fixed laying, laying through the tube and moving conditions require special requirements, etc. Need to know more information about special cable products for connecting equipment, you can in the high-voltage cable product promotion page at. |

In the ratio of the earth's sea and land, there are 71% of the ocean accounts for most of the land and 29% of the land. The ships and boats used to are no stranger to people's travel tools, and are known to human beings in six characteristics of ships.
Among them, the first, large size. Many of the container ships are transported back and forth through every day. For example, the average tonnage of container ships has developed from hundreds of boxes in the past to nearly 10,000 boxes at present. Second, high-speed. Within the last 15 years, the average speed of more than 10,000 gross tons of ships increased by about 1kn, high-speed passenger ships, cargo ships, car-passenger ferries and container ships and other development updates, such as speed 50kn roll-on roll-off high-speed five-hull type ship, speed 38kn 1400 boxes of fast container ships, speed 40kn 1000 tons of high-speed wave-piercing cargo ships. Third, the technical performance is constantly upgraded. Firstly, the economy is obviously improved, which is mainly reflected in the simultaneous reduction of fuel consumption and crew number of ships; secondly, the safety and environmental protection are greatly improved to avoid the recurring disasters of sea damage and reduce the pollution of ships to sea water and atmosphere. Fourthly, the design methods keep progressing. Direct design calculation method, ship hydrodynamic performance forecast and optimization technology, new efficient low excitation propeller design technology are widely used, and information networking will be a major technical measure for ship design in the 21st century.

Features of high-voltage cables It adopts high-frequency voltage doubler circuit, takes the lead in applying the latest PWM high-frequency pulse width modulation technology, closed-loop adjustment, and adopts large voltage feedback to greatly improve voltage stability. Use high-power IGBT devices with excellent performance and their drive technology, and adopt special shielding, isolation and grounding measures according to the theory of electromagnetic compatibility. The cable tester is high-quality, portable, and can withstand rated voltage discharge without damage. Definition of high-voltage cables: 1. Most of the 10kV urban high-voltage distribution lines use wires with insulating sheaths, but even with insulating sheaths, high-voltage wires need to use one or several porcelain bottles to insulate poles or iron towers. 2 , 35kV and above high-voltage transmission lines use bare wires, and more porcelain bottles are used for insulation due to different voltage levels. You can directly see this by observing the lines around you. Special cable type specification. FFP2 Fluoroplastic insulated fluoroplastic sheathed copper tape shielded power cable.
