Movement toward extra high voltage and large capacity of overhead transmission line induces problems of wind noise and corona noise to the peripheral areas. Accordingly, environmental concern has become a critical issue of overhead transmission line construction. To reduce environmental impact, low noise overhead conductors have been developed.Meanwhile, as the environmental impact of transmission lines, there is a problem of corrosion due to intrusion of sea salt and acid rain to the inside of the wire. To reduce the environmental impact, corrosion-resistant conductors have been developed.This paper presents various environmental technologies applied to the site and future trends.
