Medium voltage cables or MV cables, is one of the three categories of cables that is classified based on its voltage capacity. For a medium voltage cable, it is 300 to 1000 Volts. It can be used to refer to a single wire or a multi-conductor cable. For electrical power transmission, medium voltage wire or cable is typically used.
Many people may be wondering about the exact differences between medium voltage cable and low voltage cable. To make things a bit clearer, let start with the construction which is perhaps the biggest difference between low- and medium-voltage cables. Most medium-voltage designs offer extra protection to prevent the build-up of potential charges anywhere along the cable.
Mobile substation equipment, distribution of power in industrial settings and in mining to supply power to drills, shovels, and haulers, are just some of the common applications of medium-voltage cables. Another common application for medium-voltage cables is in maintenance and repairs. For example, during scheduled downtime maintenance for substations or to conduct repairs due to damage caused by a storm, utility personnel use mobile workstations. In these situations, medium voltage cables come in handy.
Tinned Copper & Oxygen-Free Copper are the two main conductor materials. Copper is used mostly in medium voltage designs, medium-voltage designs are usually constructed as follows:
A tinned copper or 99.95% copper conductor,
A conductor shield—which is usually made of some type of semiconductor material,
Insulation shield, which again can be a semiconductor or a metallic braid or tape, and
