HARD ALLOY ALUMINUM IN CONTACT WIRES - AN ENGINEERING FEASIBILITY STUDY
A study prompted by recent advances in wear performance is in progress to evaluate the ramifications of using hard alloy aluminum in contact wires and its effects on the remainder of the catenary system. Physical properties and their effects on system design are discussed. For purposes of comparison, design criteria were selected for a 25 kV, 600 A catenary. Under these conditions, a baseline system, using hard drawn copper contact wire with ACSR messenger was compared to several equivalent aluminum catenaries. An optimization study was done on both systems, which uses a computer program to assess the interaction between span and tension lengths, and to estimate in-place costs for the most economical combination.
