LV Cables. Power low voltage cables (LV cables) are used for electrical equipment with a voltage rating between 50 to 1000V for alternating current and between 75 and 1500V for direct current, thereby they are not subjected to high electric stress.
A high-voltage cable (HV cable) is a cable used for electric power transmission at high voltage. A cable includes a conductor and insulation, and is suitable for being run underground or underwater. This is in contrast to an overhead line, which does not have insulation.
