  • Difference Between High, Medium and Low Voltages

    The reason for transmitting power at high and extra-high voltage levels is to increase efficiency. The lower current accompanying the high voltage transmission allows for the use of thinner lighter-weight cables. This reduces the cost in the tower and electrical line construction. High voltages range from 115,000 to 230,000 VAC and Extra-High
