1. Application
AAC conductor is also known as aluminium stranded conductor. It is
manufactured from electrolytic ally refined aluminium, witha
minimum purity of 99.7%. AAC is used mainly in urban areas where
the spacing is short and the supports are close. All aluminium
conductors are made up of one or more strands of aluminium wire
depending on the end usage. AAC is also used extensively in coastal
regions because it has a high degree of corrosion resistance.
2. Service Performance
2.1. The permissible long-time operating temperature for aerial
conductor is 70℃.
2.2. 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.
2.3. 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.
2.4. 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. Product Performance
3.1. The electrical performance of AAC is indicated in DCΩ/km
(20℃). The resistivity of the hard aluminum wire for stranded wires
is not greater than 28.264 nΩ. m of international standard value.
3.2. The rated tensile strengh of AAC is denoted with sum of all
aluminum conductorstensile strength and steels tensile strength.
a. The tensile strength of all aluminum conductors is denoted with
the result of all cross sections of aluminum conductors multiplied
by min. tensile strength of corresponding size specified in the
standard for aluminum wire.
b. The tensile strength of all steel wire is denoted with the
result of all cross sections of steel wires multiplied by the
stress at 1% elongation of corresponding size specified in the
standard for steel wire.
4. Material Standard
4.1. The zinc coated steel wire used for AAC conforms to IEC 61089.
4.2. The hard aluminum conductor used for AAC conforms to the
standard GB/T 1179-2008 (equivalent to IEC 61089).
4.3. Production can be arranged according to customers requirements
for material standard etc. (such as ASTM B232, IEC61089, BS215,
DIN48204, BS EN50182 etc.)
