【摘要】 本文对悬垂绝缘子串的受力情况进行了认真分析，并针对允许受力最小部件进行计算公式推导，给出了允许使用的水平档距和垂直档距之间的函数关系。根据工程情况和设计参数，绘制出悬垂绝缘子垂直荷载临界曲线，便于设计应用。更多还原

【Abstract】 The stress of suspention insulato string is analped, the computing formula of allowable least stress parts is derived, and the functional relation between allowable wind span and weight span is given. According to construction and design parameters, the critical curves of vertical loads of suspention insulators are drafted to design advantage.更多还原
