Marine cable is also called marine power cable. Marine cable is a kind of wire and cable used for power, lighting and general control of various ships and offshore oil platforms in rivers and seas.
Main application: It is used for power, lighting and general control of various ships in rivers and seas, offshore oil platforms and other water buildings.
Executive standards: executive standards for marine power cables: IEC60092-350, IEC60092-353 or GB9331-88.
The main parameters of marine power cable include model and specification, number of cores, combustion characteristics, rated voltage, temperature, nominal sectional area and other main parameters.
Application scope of marine electric wire:
PVC insulated cables with rated voltage of 450/750V and below and power cables with rated voltage of 30KV and below are applicable to the fixed laying of lighting and electrical power devices with rated voltage of 450/750V and below and the power transmission and distribution system with rated voltage of 30KV and below for energy transmission and distribution. It is widely used in power, construction, mining, metallurgy, petrochemical, transportation and other departments.
Main characteristics:
1. Marine wire has good corrosion resistance and low conductor contact resistance
2. Marine wire has good weldability. Copper clad aluminum wire has the same weldability as pure copper wire because its surface is covered with a layer of pure copper.
3. Light weight, soft thread, easy processing, installation and transportation.
4. Copper clad aluminum material has the advantages of relatively low cost and relatively stable price, which overcomes the disadvantages of high cost of copper and large price fluctuation.
5. Compared with pure copper conductor, in addition to the advantages of copper conductor, its AC resistance is 2% - 5% greater than that of copper conductor (the greater the cross-sectional area, the more obvious the effect) when the DC resistance of conductor is the same as that of pure copper conductor.
