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 a conductor, which does not have insulation. High-voltage cables of differing types have a variety of applications in instruments, ignition systems, and AC and  DC  power transmission. In all applications, the insulation of the cable must not deteriorate due to the high-voltage stress, ozone produced by electric discharges in air, or tracking. The cable system must prevent contact of the high-voltage conductor with other objects or persons, and must contain and control leakage current. Cable joints and terminals must be designed to control the high-voltage stress to prevent breakdown of the insulation. Often a high-voltage cable will have a metallic shield layer over the insulation, connected to the ground and designed to equalize the dielectric stress on the insulation layer. And Low-Voltage Cables

(LV cable) are designed for use in direct burials, duct systems, and other congested urban networks where a low voltage (up to 600 volts) will be encountered. Low Voltage Power Cable  can be used in either wet or dry applications. It is abrasion, sunlight, and impact resistant and is available for purchase in several reel sizes, including reel-less packages. Our utility cables are specially designed to be easy to handle and install.
