What is it about?
The current carrying capacity is one of the key factors that restrict the safe operation of cables. Accurately grasping the current carrying capacity of cables is an important means to improve the efficiency and economic benefits of cable operation. The calculation standard of IEC60287 not only ignores the differences between different types of cables, but also makes it difficult to make timely calculation and correction according to the changes of cables during operation. Therefore, taking WDZ-YJY3×16 cable as an example, the electromagnetic-thermal coupling simulation model is established and the finite element simulation analysis is carried out.

Why is it important?
According to our research results, the cable ampacity can be obtained more accurately, so that relevant personnel can grasp the operation status of the cable in time and take corresponding measures to ensure the efficient and safe operation of the cable.
Perspectives
I hope that the research results of this article can bring some reference to the current cable industry, and I will be very happy if the research ideas in this article can inspire you or bring you new ideas.
