Aluminium Alloy Conductor Cable
AAC cable is used in overhead electric power transmission and distribution lines with various grade voltages. Under the same weight, AAC is with higher DC resistance and lower cost than copper conductor. Aluminum is light and be easy to lay. AAC cable is composed by bare concentric-lay-stranded aluminum wires with a straight round central aluminum wire surrounded by one or more layers of helically laid aluminum wires.
The rated voltage of the cable for a given application shall be suitable for the operating conditions in the system in which the cable is used,and is expressed in the form of Uo/ U(Um)kV.
Uo-The rated power-frequency voltage between conductor and screen or metallic-sheath,for which the cable designed;
U-The rated power-frequency voltage between conductors, for which the cable designed:
Urn-The maximum value of the "hight system voltage " for which the equipment may he operated.
Rated voltaged of cable applied in three phrase system are given in table
