摘　　要：在双地线系统中,OPGW同匹配地线的缆径、自重、额定抗拉强度、弹性模量、线膨胀系数等参数往往有差异,有时存在着相互牵制、互相配合的问题。结合西北750 kV示范工程应用实例,依据工程大气使用条件,提出了OPGW与匹配地线的力学配合要素和弧垂配合与公差控制的基本要求。满足了这些要求,OPGW就可以长期安全稳定运行。In the double - ground - wires system OPGW has many differences in the cable diameter, self - weight, rating tensile strength, elastic modulus, linear expansion coefficient and other parameters to the matched ground wires, which are mutually tied up and matched. In combination with the practical example of 750 kV demonstration project in north -west China and according to the engineering atmospheric applicable conditions the author gives out the key points for the mechanical matching of OPGW with matched ground wire and basic requirements for sag matching, with allowance control. In meeting the previous mentioned conditions OPGW can be under safe and reliable operation for a long term.
