ACSR Moose Conductors Improve Power Transmission Efficiency
ACSR Moose conductors, a steel-reinforced aluminum cable design, remain a core component of extra-high-voltage transmission and distribution networks worldwide. The 54/7 construction combines aluminum strands for conductivity with a steel core for mechanical strength. Its balance of tensile performance and electrical efficiency has made it a long-standing specification for long-span and high-capacity power projects.
Technical design and performance
The ACSR Moose conductor uses 54 aluminum strands around a seven-strand steel core. This composite design allows the cable to carry high mechanical tension while limiting sag, reducing structural loads on towers and poles. The aluminum outer strands provide conductivity, while the steel core supports long-span installations.
The specification is produced to international standards including EN50182 and BS215-2, which cover material purity, stranding, mechanical strength and electrical resistance. Those requirements support reliable operation across different climates and terrains, according to the standards' technical criteria.
Specifications
The conductor's nominal aluminum area is 500 mm², with a total area of 597.20 mm². Its outer diameter is 31.77 mm, rated tensile strength is 161.10 kN, and total weight is 1999 kg/km. At 20°C, DC resistance is 0.05470 Ω/km, and allowable ampacity is 763 amps.

Applications and market factors
ACSR Moose conductors are used in applications ranging from extra-high-voltage transmission lines to private power facilities connected to distribution networks. Their lighter weight reduces installation difficulty and allows deployment on wood poles, steel towers and other structures. The specification has been used in projects in several regions, including South Africa, Southeast Asia, Kenya and Iran.
Market prices for the conductor are influenced by aluminum and steel raw material costs, manufacturing expenses and global logistics conditions. Its long service record has established the specification as a common choice where high strength, manageable sag and reliable conductivity are required.
