Conductor(AAAC) have been widely used in power transmission lines with various voltage levels, and also used in power lines across great rivers, heavy ice area, and other places special geographical characteristics. The conductor have excellent advantages of high strength, large current carrying capacity and good catenary property as well as wear-resistance, anti-crush and corrosion-proof with simple structure, convenient installation and maintenance, low cost for the line, large transmission capacity.
Conductor(AAAC) bear conductor meets or exceeds the following ASTM Specifications:
B-398 Aluminum Alloy 6201-T81 Wire for Electrical Purpose.
B-399 Concentrical-Lay-Stranded 6201-T81 Aluminum Alloy Conductors
3. Product Performance
(1). The electrical performance of AAAC is indicated in DCΩ/km(20oC). The resistivity of aluminum alloy wire for stranded wires is:
LHA1: Not greater than 32.840nΩ. M
LHA2: Not greater than 32.530nΩ. M
(2). The rated tensile strength of AAAC is denoted with the result of total cross-section areas of all aluminum alloy conductors multiplied by min. Tensile strength of corresponding size specified in the standard for aluminum alloy wire.
4. Material Standard
The high-strength aluminum alloy conductor used for AAAC conforms to the standard JB/T 8134-1997(equivalent to IEC 60104: 1987).
