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.

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. |

The space available for cable routing in the vehicle deserves careful consideration. The need for tight bend radii in only one specific area of the vehicle results in increased flexibility requirements for the overall cable. Avoiding the problem of tight bends makes a lot of sense if it is possible to make small changes in the overall design. The cable does not necessarily have to be the most flexible. The exact definition of the bending forces, combined with the structure and corresponding test equipment, enables the cable designer to create the most suitable design for the application. Especially for cables with larger cross-sections, substituting a more flexible or conventional structural design for a highly flexible design can significantly reduce costs. Of course, the optimization of the shielding effect of the cable should be mentioned: a defined shielding effect in a certain frequency range is very necessary for the development of the cable. The shielding effect without information about the frequency is not very useful, which can lead to solutions with excessive dimensions and the use of expensive combined shielding, which is no longer necessary from a technical point of view. Normally, theoretical calculations can be used to give an expected effect value for consideration in the development and design stage of electric vehicle cables. Then, the shielding effect of high-voltage cables is verified by means of tests in kind.
