ACSR ASTM B 232

Product Description

ACSR(Aluminum Conductor Steel Reinforced) is widely used in the overhead power distribution system .

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 occurring 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 *****, 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 installation, the arc downing stress of all the conductors should be the same.  Within 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 ***** of corresponding size specified in the standard for aluminum wire.
 

(3).The rated tensile strength of ACSR is denoted with sum of all aluminum conductor tensile strength and steels tensile strength.
