ACSR conductor

Product Description

APPLICATION:

ACSR and AAC are mainly used as bare overhead transmission cable and as primary and secondary distribution cable. It is also suitable for laying across basins, rivers and valleys where special geographical teatures exist.

STRUCTURE:

Aluminum alloy ****-H**9 wires, concentrically stranded about a steel core. Core wire for ACSR is available with class A, B, or C galvanizing; "aluminized" aluminum coated (AZ); or aluminum-clad (AW). Additional corrosion protection is available through the application of grease to the core or infusion of the complete cable with grease.

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
 

SPECIFICATION:

1. all aluminium conductor (AAC)

2. all aluminimum alloy conductor(AAAC)
3. aluminum conductor steel reinforced (ACSR)
4. anti-corrosion type ACSR
5. aluminimum conductor aluminimum clad steel reinforced(ACSR/AW)

6. rear earth aluminimum conductor steel reinforced(ACSR/RE)

7. aluminimum conductor aluminimum alloy reinforced(ACAR)

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 connecctors are install the connecting tube should be painted by moisture-proof varnish in order to protect it from corrsion.

4. Under installaion,the arc downing stress of all the conductors should be the same.With in the permissibledistance of crossing buildings or dropping to the ground,the stress can be ****5% higher than regular stress

 

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.
