摘　　要：介绍了超高压、特高压输电线路用＂JL/G1A-1400/135-84/19＂大截面钢芯铝绞线生产工艺流程,主要原材料选择A8型号的铝杆,利用七道次拉拔,总压缩率达到了77.56%,钢芯用镀锌钢丝上锌量达到了262 g/m2,扭转次数22~24,抗拉强度达到1 486 MPa,绞线的截面积达到了1 400 mm2。经检测,研制出的钢芯铝绞线各项力学性能、结构尺寸、电阻率等指标均达到了研制目标要求。The paper introduces the production process flow of JL/G1A-1400/135-84/19 steel cored aluminum strand used for ultrahigh voltage power transmission line. Main material： A8 aluminum rod; drawing passes： 7; total reduction rate： 77.56%; zinc on galvanized steel wire for steel core： up to 262 g/m% turning number： 22-24; tensile strength： 1 486 MPa; strand section： 1 400 mm2. Inspection showed that all indices of the developed steel cored aluminum strand such as mechanical properties, structure size and resistivity fulfill the goal of research and development.
