Thermal Analysis of Cable Routes with Joints or Other Discontinuities

Energies
The paper addresses rare issue in cable ampacity calculations, namely the presence of discontinuities along the routes. One which occurs in almost all cable installations is the presence of joints.

The effect of PV modules on temperature conditions of nearby power cables

Frontiers in Energy Research
The highest permissible load of power cables (ampacity) depends strongly on the ambient temperature, which in the case of cables surrounded by free air is generally assumed to be 25°C.
