采用高强钢丝生产梢径150毫米、长10米以下、壁厚40毫米的6至10千伏环形预应力电杆,在我厂虽说已有多年的历史,但杆段弯曲问题,特别是在距梢端2米范围内的弯曲问题一直没有得到较好的解决。为此,我们把这一问题作为技术攻关的一个主要课题,进行了一些探讨。现试述如下。 The use of high-strength steel wire to produce 6 to 10 kV annular prestressed poles with a diameter of 150 mm, length of 10 meters or less, and a wall thickness of 40 mm, although we have had many years of history in our plant, the bending of the rods, especially in the distance The bending problem within 2 meters of the tip has not been well resolved. To this end, we have taken this issue as a major topic of technical research and conducted some discussions. Now try the following.
