ASTM B231 Standard All Aluminum Conductor With 99.7% Purity
All Aluminum Conductor widely used in power transmission lines with various voltage levels. since they have such good characteristics as simple structure, convenient installation and maintenance, low cost for the line, large transmission capacity and are also suitable for laying across rivers and valleys .
Service Performance
(1).The permissible long-time operating temperature for aerial conductor is 70oC.
(2).Under the circumstance that rare climate occurs and high ice coverage rate, 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 can’t be prominent. Otherwise, the force on the operating conductors will be unbalanced. After connectors are installed, the connecting tube should be painted by moisture-proof varnish in order to protect it from corrosion.
