Overhead Bare AAC Conductor/DIN 48201

Specifications

1.Specification

AAC are composed by bare concentric-lay-stranded aluminum wires with a straight round central aluminum wire surrounded by one or more layers of helically layed aluminum wires.

2.Application

(1)AAC are used in overhead electric power transmission and distribution lines with various grade voltages.

(2)AAC (All aluminum conductor) are suited for overhead power line. 

(3)AAC conductors are used in line designs that do not require the strength of ACSR type conductors while maximizing current carrying capacity.

(4)Under the same weight, AAC is with higher DC resistance and lower cost than Copper conductor.

3.Supply

We can supply this conductor according to different recognized standards,such as IEC61089, BS215, ASTM B231, CSA C49, DIN480201, JIS C3109.

Customer special specification also can be satisfied.

4.Performance

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

(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)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.

(4)The electrical performance of AAC is indicated in DCΩ/km(20°C). The resistivity of the hard aluminum wire for stranded wires is not greater than 28.264 nΩ. m of international standard value.
