Aluminum Conductor Steel Reinforced(ACSR )

Aluminium Conductor Steel Reinforced (ACSR) is concentrically stranded conductor with one or more layers of hard drawn 1350-H19 aluminium wire on galvanized steel wire core. The core can be single wire or stranded depending on the size. Steel core wire is available in Class A , B or Class C galvanization for corrosion protection. Additional corrosion protection is available through the application of grease to the core or infusion of the completed conductor with grease.The proportion of steel and aluminium in an ACSR conductor can be selected based on the mechanical strength and current carrying capacity demanded by each application

2,Product description

ACSR conductors are recognized for their record of economy, dependability and favourable strength / weight ratio. ACSR conductors combine the light weight and good conductivity of aluminium with the high tensile strength and ruggedness of steel. In line design, this can provide higher tensions, less sag, and longer span lengths than obtainable with most other types of overhead conductors.

1. Applications

ACSR conductors 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

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 ACSR is indicated in DCΩ/km (20oC).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 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. Standard:Production can be arranged according to customers requirements,the products we manufactured meets or exceeds the requirements of all international standards like ASTM, AS, BS, CSA, DIN, IEC, NFC, SS -etc
