The 250 MCM Valerian AAC (All Aluminum Conductor) is a bare overhead transmission cable used for low and medium voltage power distribution. Manufactured with high-purity 1350-H19 aluminum, this stranded conductor is known for its excellent conductivity, lightweight construction, and corrosion resistance. It is a cost-effective choice for a wide range of overhead electrical applications, especially where mechanical strength requirements are moderate.
Applications
The 250 MCM Valerian AAC conductor is widely used in:
-
Urban overhead distribution systems
-
Coastal and marine environments
-
Shipyards and offshore platforms
-
Railways and mass transit systems
-
Primary and secondary distribution lines
Its resistance to corrosion, particularly in salty or humid atmospheres, makes it ideal for coastal installations. Its lightweight and easy handling characteristics also simplify installation and reduce hardware costs.
Advantages
-
Economical: Lower material cost compared to ACSR or AAAC
-
Lightweight: Easier transportation and installation
-
Corrosion Resistant: Excellent for coastal or industrial atmospheres
-
Flexible: Suitable for a wide range of overhead transmission duties where high tensile strength is not required
Standards
The 250 MCM Valerian AAC conductor complies with the following international standards:
-
ASTM B-230 – Aluminum 1350-H19 Wire for Electrical Purposes
-
ASTM B-231 – Concentric-Lay-Stranded Aluminum 1350 Conductors
Construction
AAC Valerian conductor is constructed as follows:
-
Material: EC-grade Aluminum 1350-H19
-
Stranding: Concentric-lay-stranded construction
-
Helical Configuration: Each successive layer contains six more wires than the layer beneath it
-
Lay Direction: Outer layer is right-hand lay, alternating in successive layers
This uniform construction provides consistent conductivity and reduces skin effect losses.
