一、电杆选择有关计算电杆高度主要应满足导线距地面或跨越物的距离要求; 电杆强度应验算地面弯矩能否满足要求。为计算方便采用了“换算风压值”的概念。各种电杆允许换算风压值为: P_1=M/(l·h)·10 (1·1)式中 P_1——电杆允许换算风压值; M——所用电杆的标准弯矩(公斤-米); l——档距(米);

First, the choice of poles The calculation of the pole height should mainly meet the requirements of the wire from the ground or across the distance requirements; pole strength should be verified ground bending can meet the requirements. For calculation convenience adopted the concept of “conversion wind pressure value”. All kinds of poles allow the conversion of wind pressure value is: P_1 = M / (l · h) · 10 (1.1) where P_1 - pole allows the conversion of wind pressure value; Moment (kg - meter); l - span (m);
