Low Voltage Aluminum Conductor Steel Reinforced ACSR Overhead Conductor
Aluminum Conductor Steel Reinforced are widely used for electrical power transmission over long distances, since they are ideal for Long overhead lines spans. They are also used as a messenger for supporting overhead electrical cables.
CONSTRUCTION
A solid or concentric stranded central steel core is surrounded by one or more layers of concentric stranded aluminum alloy 1350. The wire is protected from corrosion with a zinc coating.
Service Performance:
(1). The permissible long-time operating temperature for aerial conductor is 70℃.
(2). Under the circumstance that rare climate is occurring and ice coverage rate low in heavy ice area, the biggest stress of cable at the lowest point of the sag should not exceed 60% 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.
(4). Under installation, the arc downing stress of all the conductors should be the same. With in the permissible distance of crossing buildings or dropping to the ground, the stress can be 10-15% higher than regular stress.
