Abstract

Elements that constitute electric cables require a compromise between mechanical and electrical characteristics to achieve the desired functions, the choice of materials constituting each element involves economic and technical factors and requires a broad knowledge of materials to choose from. Unfortunately, by the external environment and operating conditions of these cables, the insulation material is subjected to various kinds of stresses, without forgetting the moisture effects that could not be prevented on the other elements of cable despite the presence of peripheral protective sheaths. The aim of this work is to study the mechanical behavior of underground electrical cable components. For this reason, a comparative study between the different specific energies in elastic phase of cables elements is performed. We concluded that the outer sheath has a specific energy in elastic phase considerably higher compared to the other elements energies, this elastic energy is extremely important for the used material, it increases the level of its performance and its endurance against mechanical stress. Therefore, it makes the material more reliable and increases its availability as well as its mechanical life time.
