Aluminum Conductor Steel Reinforced(ACSR)3

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 70 o C. (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. (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 10-15% higher than regular stress. 3.Product Performance (1).The electrical performance of AAC and ACSR is indicated in DCΩ/km(20 o C).The resistivity of the hard aluminum wire for stranded wires is not greater than 28.264 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 17048-1997(equivalent to IEC 60889:1987). (2).The zinc coated steel wire used for ACSR conforms to IEC 60888:1987. (3).Production can be arranged according to customers requirements for material standard,etc. Construction of All Aluminum Conductor and Aluminum Conductor Steel Reinforced 5.Chinese Standard New Type Original Type Name Range of Sectional Area JL LJ All Aluminum Conductor 10-1500 JL/G1A JL/G1B JL/G2A JL/G2B JL/G3A LGJ Aluminum Conductor Steel Reinforced 16-1250 JL/G1AF JL/G2AF JL/G3AF LGJF Corrosion-Resistant Aluminum Conductor Steel Reinforced 16-1250 JLHA1 JLHA2 LHAJ All Aluminum Alloy Conductor 16-1250 JLHA1/G1A JLHA1/G1B JLHA1/G3A JLHA2/G1A JLHA2/G1B JLHA1/G3A LHAGJ Aluminum Alloy Conductor Steel Reinforced 16-1120 JL/LHA1 JL/LHA2 LLHAGJ Aluminum Conductor Aluminum Alloy Reinforced 16-1400 JL/LB1A LLBGJ Aluminum Conductor Steel Coated Aluminum Reinforced 16-1250 JLHA2/LB1A JLHA1/LB1A LHALBGJ Aluminum Alloy Conductor Aluminum Coated Steel Reinforced 16-1250 JG1A JG1B JG2A JG3A GJ All Steel Stranded Conductor 6-63(27.1mm 2 -427mm 2 ) JLB1A JLB1B JLB2 LBGJ Aluminum Coated Steel Conductor 4-200(12mm 2 -600mm 2 )
