Analysis on selecting application of energy-saving conductors in overhead transmission line construction

Comparing with common aluminium conductor steel reinforced(ACSR) with equal outside diameter, the DC resistance of energy-saving conductor is lower, So applying it in transmission lines can enhance conductivity and decrease line losses. This paper introduces the characters of three new energy-saving conductors, analyzing the technical characteristics and economic characteristics of energy-saving conductor and common aluminium conductor steel reinforced. A general method of selecting energy-saving conductors is proposed binding with the project.
