Abstract: In recent years, China has witnessed significant progress in the design and manufacturing technologies of electric conductors. Based on the technical characteristics of three new types of energy-saving conductors, including high conductivity aluminum conductor steel reinforced, high conductivity aluminum conductor aluminum alloy reinforced and medium strength all aluminum alloy conductor, a study is carried out in this paper on the performance and application scope of above-said conductors. The performance of the conductors is compared in terms of electrical and mechanic characteristics. Also, the complete fittings are compared according to their strain clamp and splicing sleeve schemes. The effects of tower head gap and tower load on towers are studied. The construction technology is investigated from construction equipment, conductor pay-off and crimping. Based on the above-said study results, guidelines are proposed for application of three new types of energy-saving conductors.
