Damaged aluminum conductor stranding yields line loss through the transmission system. AFL has two methods of repairing transmission conductors when some of the aluminum stranding has been impaired or severed. The type of repair accessory used depends on the number of strands damaged, operating temperature of the conductor, and the tooling desired to install the assembly. Compression repair sleeves require a die set and hydraulic press, while repair rods installation is completed by wrapping a rod set around the damaged conductor. 


AFL offers the Quick Compress® RS series and Standard Compression 5200 series for conductors operating at or below 100°C and the 5200HT series repair sleeve assemblies for conductors operating at elevated temperatures at or below 250°C. The AFL AAR Rods series can be applied to standard operating temperature and elevated temperature stranded aluminum conductors. Both options are discussed in this white paper.
