ACSR
1.
Applications
Conductor(AAC and ACSR) 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 *0oC.
(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 *0% 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 ****5% higher
than regular stress.
3.Product Performance
(1).The electrical performance of AAC and ACSR is indicated in
DCΩ/km(*0oC).The
resistivity of the hard aluminum wire for stranded wires is not
greater than *8.**4 nΩ. m of international standard value.
(2).The rated tensile strength of AAC is denoted with the result of
total cross-section of all aluminum conductors multiplied by
min.tensile of corresponding size specified in the standard for
aluminum wire.
(3).The rated tensile strengh of ACSR 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
(1).The hard aluminum conductor used for AAC and ACSR conforms to
the standard GB/T *********7(equivalent to IEC ****9:***7).
(2).The zinc coated steel wire used for ACSR conforms to IEC
****8:***7.
(3).Production can be arranged according to customers requirements
for material standard,etc.
