Application
ACSR (aluminum conductor steel reinforced) conductor is widely used in power transmission lines with various voltage levels due to its advantages such as simple structure, low cost, etc. It is also suitable for laying across rivers and valleys where special geographical teatures exist. According to different sag and tensile requirements, steel wires of different tensile strength can be used for ACSR conductor.
Construction
1. Conductor: 1350 hard-drawn aluminum
2. Tensile strength of aluminum wire: 160-200 MPa
3. Elongation at break: 1.4%-2.3%
4. Reinforced core: steel (different strength levels available)
5. Zinc coating: class A, B and C
6. Tensile strength: normal, high, extra-high and ultra-high grades available
7. Sectional area: 10-1500mm2
8. Construction: contrically stranded round conductor
9. Min. bending radius: 30 times cable radius
