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.

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.
