1. Applications

AAAC conductors 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 70oC.

(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 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 installaion,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.

3. Properties

AAAC (All Aluminum Alloy Conductor) referred to have higher strength but lower conductivity than pure aluminum. Being lighter, alloy conductors can sometimes be used to advantage in place of the more conventional ACSR; Having lower breaking loads than the latter, their use becomes particularly favourable when ice and win loadings are low.

We can supply this conductor according to different recognized standards, such as BS EN50183, IEC61089, ASTM B399,DIN 48201, customer special specification also can be satisfied.
