POWER SECTOR
Extra High Voltage (EHV) transmission lines are critical components in the electrical power distribution network, designed to carry large amounts of electricity over long distances with minimal losses. Typically, EHV lines operate at voltages ranging from 220 kV to 765 kV, which allows for efficient power transfer across vast networks. The design of EHV lines often includes bundled conductors to reduce the electric field intensity, thereby increasing the corona inception voltage and minimizing energy loss due to the corona effect. Moreover, these lines are equipped with specialized equipment like corona rings, surge arresters, and Optical Power Ground Wire (OPGW) cables to protect against lightning strikes and other electrical surges.
OPGW cables serve a dual purpose: they ground the line and provide a medium for high-speed data transmission, which is essential for modern power system management and communication. The implementation of EHV lines has revolutionized the way electrical power is transmitted, ensuring that even the most remote areas have access to reliable electricity. As the demand for electricity grows and the sources of generation become more diverse and geographically dispersed, the role of EHV transmission lines in maintaining grid stability and efficiency becomes increasingly important.
