The overhead transmission line is generally categorized into three classes,[3]depending on the length of the line: Lines shorter than 50 km are generally referred to as shorttransmission lines. Lines between 50 km and 150 km are generally referred to as mediumtransmission lines. Lines longer … Visa mer An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy across large distances. It consists of one or more uninsulated electrical cables (commonly multiples … Visa mer By operating voltage Overhead power transmission lines are classified in the electrical power industry by the range of voltages: • Low voltage (LV), less than 1000 volts, used for connection between a residential or small commercial … Visa mer Insulators must support the conductors and withstand both the normal operating voltage and surges due to switching and lightning. … Visa mer A compact overhead transmission line requires a smaller right of way than a standard overhead powerline. Conductors must not get too close to each other.
