ACSRAS (Aluminium Conductor Aluminium Clad Steel Reinforced)

ACSRAS (Aluminium Conductor Aluminium Clad Steel Reinforced)
Product Overview
As a professional bare conductor supplier, Hebei Yingshang Aluminum
Industry manufactures high-performance ACSRAS conductor (Aluminium Conductor
Aluminium Clad Steel Reinforced) designed for overhead transmission lines
operating in corrosive, coastal, and heavy-pollution environments.
ACSRAS is an upgraded composite overhead conductor featuring a structural
combination of a high-conductivity aluminium outer layer and an aluminium
clad steel reinforced core. By replacing the traditional galvanized steel core
used in conventional ACSR with an aluminium-clad steel core, this conductor
retains the high tensile strength of steel while effectively eliminating
electrochemical corrosion between dissimilar metals. The result is improved
corrosion resistance, stable electrical performance, and extended service life
in harsh operating conditions.
 
What Is ACSRAS Conductor?
ACSRAS (Aluminium Conductor Aluminium Clad Steel Reinforced) is a composite
overhead conductor consisting of:
Outer layers: Hard-drawn aluminium strands for efficient electrical
conductivity
Core: Aluminium-clad steel wires that provide high tensile strength and
enhanced corrosion protection
Unlike conventional ACSR, the aluminium-clad steel core improves resistance to
atmospheric corrosion while maintaining excellent mechanical performance,
making aluminium clad steel reinforced conductor a preferred choice in harsh
or corrosive environments.
Conductor Structure
Aluminium Clad Steel Reinforced Core
The reinforced core consists of 1, 7, or 19 strands of aluminium clad steel
wires, concentrically twisted together. Each wire features a low-carbon steel
core fully coated with an aluminium layer, with the aluminium thickness
accounting for not less than 10% of the steel wire diameter.
Positioned at the center of the conductor, the aluminium clad steel core
provides the primary mechanical strength. Because the aluminium coating shares
the same base material as the outer aluminium conductor layer, electrochemical
corrosion caused by heterogeneous metal contact is effectively avoided.
Conductive Aluminium Layer
High-purity aluminium wires are concentrically stranded around the aluminium
clad steel core to form the conductive layer. The wires have a circular cross-
section, with the number of outer strands increasing according to conductor
size.
The aluminium layer serves as the main path for electrical current
transmission. A controlled lay length of 12–16 times the outer
diameter ensures tight bonding with the reinforced core, maintaining
structural integrity and stable electrical performance.
