我国的钢产量较低,国家要求在电力线路上尽可能多采用钢筋混凝土电杆。普通水泥制造的电杆,在一般地区是比较经济、实用的,可使用到50年以上;但在条件恶劣的盐碱等地区,因有腐蚀破坏作用,如无防治措施,则不能经久、耐用,一般使用7～8年即严重纵裂.为了探索电杆防腐问题的途径,本文就内蒙西部盐碱区,特别是乌拉山电厂出口处各条线路的电杆耐腐破坏现象,谈谈腐蚀原因与防治意见. China’s steel production is low, and the country requires the use of reinforced concrete poles as much as possible on power lines. The poles made of common cement are generally economical and practical in the general area and can be used for more than 50 years. However, in areas with harsh saline conditions, due to corrosion and destruction, if they have no preventive measures, they cannot be durable and durable. Generally speaking, severe longitudinal cracks are used for 7 to 8 years. In order to explore the ways to protect poles from corrosion, this article talks about the corrosion resistance of poles in the various lines of the saline-alkali area in western Inner Mongolia, especially at the exit of Wulashan Power Plant. Reasons and prevention advice.
