ARMOR
The armor provides mechanical protection to the cable from impacts and/or abrasions, from rodents, and also to provide greater tensile strength during installation and handling. In addition to mechanical protection, the armor can serve as a shield for electromagnetic fields and, in special cases, as a ground conductor. Consequently, the mechanical and electrical requirements during cable installation and operation determine the type of armor to be used.

INSULATION
The insulation is a casing of dielectric material placed around the conductor and designed to withstand the electrical voltage. It is a fundamental part of the cable that determines its performance in terms of nominal voltage, capacity, thermal behaviour.

STRANDING
During the stranding process, conductors or cables, with a given circular dimension, are twisted helically around a central core, made of a metal wire or textile fiber, to form a conductor with a larger dimension. The purpose is to improve the mechanical properties (i.e. flexibility), vibration resistance, handling and prepare the conductor for the subsequent process.

STRINGING
The process of stranding is an operation by which multiple electrical conductors are joined together to form a multiple electrical cable.

SHEATHS
At the end of the entire manufacturing process, electrical cables may require an additional external protective coating called sheath: it can be composed of polymers, rubber or lead and, like the insulation, is applied through a high-temperature extrusion process.
