A power cable is a cable that contains one or more conductors and is intended to transmit electrical power. Depending on the region, the standards for power cables have varying specifications that include, but are not limited to, the voltage rating, type of insulation, type of conductor, and environmental conditions. Meeting these standards enable the cables to perform effectively and safely for their intended use. Regulations vary from region to region, however, there are some internationally accepted regulations that enable proper quality and safety. These limits, as we have described above, are important for proper power cable selection for various applications.
