All Aluminum Conductor (AAC) & Aluminum Conductor Steel Reinforced (AC

详情

1. Applications AAC and ACSR have been widely used in power transmission lines with various voltage levels, because they have such good characteristics as simple structure, convenient installation and maintenance, low cost large transmission capacity. And they are also suitable for laying across rivers valleys and the places where special geographical features exist. 2. Service Performance (1). The permissible long-time operating temperature for aerial conductor is *0oC. (2). Under the circumstance that rare climate is occuring and ice coverage rate low in heavy ice area, the biggest stress of cable at the lowest point of the sag should not exceed *0% of the short-time destructive power. (3). When connecting conductors, the conductor beside the connecting tube cant be prominent. Otherwise, the force on the operating conductors will be unbalanced. After connectors are install, the connecting tube should be painted by moisture-proof varnish in order to protect it from corrosion.
