ACSRAS (Aluminium Conductor Aluminium Clad Steel Reinforced)
ACSRAS (Aluminium Conductor Aluminium Clad Steel Reinforced)
Product Overview
As a professionalbare conductor supplier,Hebei Yingshang Aluminum Industrymanufactures high-performanceACSRAS 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 ahigh-conductivity aluminium outer layerand analuminium 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, makingaluminium clad steel reinforced conductora preferred choice in harsh or corrosive environments.
Conductor Structure
Aluminium Clad Steel Reinforced Core
The reinforced core consists of1, 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 fornot 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 of12–16 times the outer diameterensures tight bonding with the reinforced core, maintaining structural integrity and stable electrical performance.
