G(Z)TACSR [Gap Type Conductor] and ZT(XT)ACIR [INVAR Conductor] are unique conductors to up-rate the existing transmission line's capacity with similar sag by simply replacing the existing ACSR. To cope with new subjects, such as harmony with the environment and application for telecommunication in several transmission line project, NS-TACSR [Noise-suppressed conductor] and OPGW [Composite fiber optic overhead ground wire] have been developed. AS wires [Aluminum-clad Steel wires] have been used for the conventional ground wire, component wire of OPGW or as the core wire of ACSR/AS conductor.
