摘　　要：国网典设2G模块中220kV双回直线塔上的子导线水平排列方式,在导线防风偏、铁塔抗横向风、导线防覆冰方面优于垂直排列方式,并可在悬垂串下方悬挂重锤。若中相悬垂串改为V形串,可实现塔头上、中相导线约-11°和下相导线约-4°的静态负保护角,从而降低雷电绕击导线跳闸率;对于国网典设2G模块,经技术比较,V型串夹角为100°、并挂1片重锤的摇摆角校验曲线与Ⅰ型悬垂串的摇摆角校验曲线基本接近。The split tangent conductor＇s horizontal arrange is considered better than it＇s vertical arrange in against wind and ice, if ＂V＂ string is adopted on the middle phase, the static negative conductor protected angle about -11° on the upper and middle phase conductor and -4°on the below phase conductor can be achieved. When ＂V＂ string＇s angle is 100°, and 1 piece is put on the ＂V＂ staing, it＇s swing angle check curve is basically coincide with ＂V＂ string.
