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.

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.

Experiments have shown that for specific high-voltage cables, it can often be tailored through the optimization of cross-section, temperature requirements, flexibility and shielding effect. Weight and cost savings can be demonstrated, and oversizing and excessive components can be avoided. Perfectly intricate design and use of high-quality materials, the result will be expensive cable costs. For more information about high voltage cables, please visit or search: https://www.omgevcable.com/Cases/ Optimization of cross-sectional area and temperature class: The selection of cables is mostly based on the indicators of ambient temperature and transmission current. The most important properties in this regard are the "cable cross section" and the "heat resistance class of the material used for the cable". Optimization of flexibility and shielding effect: Cable design appearance and internal core effect, design the most suitable cable for the application: through different conductor specifications may lead to cost and weight increase, larger outer diameter. Of course, considering the highest possible load current and ambient temperature, it will lead to the use of large cross-section cables and high temperature resistant materials, such as organic fluorine or silicon materials. However, manufacturers use cable standards formulated by materials such as PVC or XLPE. Determining the relationship between current and load ambient temperature is very meaningful from a technical and economic point of view. The periodic dynamic current peaks of the real drive should be considered, allowing a reasonable definition of the worst case load current and peak current.
