Bare AAC All Aluminium Conductor For Distribution Lines

Application of AAC All Aluminium Conductor

AAC All Aluminium Conductor has 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 places where special geographical features exist.

AAC All Aluminium Conductor Service Performance

(1).The permissible long-time operating temperature for aerial conductor is 70^oC.

(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.

(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.
