Quick Details

Packaging & Delivery

Packaging Details: New wooden drum, Reel, Circle or according to customer's request
Delivery Time: According to customer's request, usually 2-4 weeks.

Description

1. ACSS is a composite concentric-lay stranded conductor. Steel strands form the central core of the conductor with one or more layers of aluminum 1350-0 wire stranded around it.
2. The steel core carries most or all of the mechanical load of the conductor due to the "0" (fully annealed or soft) temper aluminum. Steel core wires are protected from corrosion by galvanizing, aluminizing, or mischmetal alloy coating.

Service Performance

1. High tensile strength
2. Long life
3. Light in weight
4. Suitable for high as well as extra high overhead

Construction

ACSS is a composite concentric-lay stranded conductor. Steel strands form the central core of the conductor with one or more layers of aluminum 1350-0 wire stranded around it. The steel core carries most or all of the mechanical load of the conductor due to the "0" (fully annealed or soft) temper aluminum. Steel core wires are protected from corrosion by galvanizing, aluminizing, or mischmetal alloy coating. Corrosion protection should be selected to suit the environment to which the conductor will be exposed. High strength steel core is also available.

Features

1. Conductor: hard drawn 1350 aluminum
2. Sectional area: 10~1000mm2
3. Tensile strength of individual wire: 160~200 MPa
4. Elongation at break: 1.5%~2.3%
5. No. of strands: 7, 19, 37, 61, 91
6. Sectional area: 10~1500mm2
7. Consutruction: concentrically stranded round conductor
8. Min. bending radius: 30 times cable radius
9. Conductivity: 61% IACS

Application

ACSS is used for overhead distribution and transmission lines. It is designed to operate continuously at elevated temperatures up to 250°C without loss of strength; it sags less under emergency electrical loadings than ACSR; it is self-damping if prestretched during installation; and its final sags are not affected by long term creep of aluminum. The advantages make ACSS especially useful in reconductoring applications requiring increased current with existing tensions and clearances, new line applications where structures can be economized because of reduced conductor sag, new line applications requiring high emergency loadings, and lines where aeolian vibration is a problem.
