Power, data, and control cables are subjected to rigorous testing and certification processes to ensure maximum reliability and safety of the installation. These cables must comply with international electrical cable standards, which provide a set of requirements, recommendations, and procedures for the design, manufacture, testing, and installation of cables, such as their electrical conductivity, mechanical strength, or resistance to environmental factors. The most common international standards for electrical cables are as follows.
