• A high-voltage cable (also called high-tension or HT cable) is a cable designed to carry electric power at voltages significantly above what is used for distribution to end users (commonly tens to hundreds of kilovolts). Wikipedia+2zgsm-wireharness.com+2
• They are fully insulated systems: the cable itself includes insulation, semiconducting layers, metallic shielding, and protective layers. They differ from overhead lines by having full dielectric insulation around conductors. Wikipedia+1
• High-voltage cables are used in power transmission (between substations, power plants, grid interconnections), in underground or submarine links, or between high-voltage equipment in substations.

Medium voltage (MV) cables are power cables designed for voltages between approximately 1 kV and about 36 kV (often many manufacturers define up to 35 kV) in distribution networks. They bridge the gap between lowvoltage (LV) and high-voltage (HV) systemss.

Used for power distribution in industrial, utility, commercial, and infrastructure systems. Examples include connecting substations, industrial plants, distribution feeders, underground and overhead runs, etc.

Low voltage cables are electrical cables used to carry voltages typically below 1,000 volts (1kV). They are commonly used in residential, commercial, and industrial applications for power distribution, lighting, communication, and control systems.
