High Conductivity
Compared to solid aluminum wire of the same diameter, Alumoweld has a conductivity of 33 percent. For high frequency applications where "skin effect" is a factor, e.g. lightning faults, the conductivity of Alumoweld approaches 100 percent of that of solid aluminum, at a fraction of the cost. When Alumoweld is combined with aluminum wires in composite conductors, a wide range of strength and conductance characteristics is possible.
Corrosion Resistance Means Long Life and Reliable Performance.
The thick aluminum cladding of Alumoweld -ten percent of the wire radius- provides a high degree of corrosion resistance, resulting in longer service life and reduced maintenance. Alumoweld offers corrosion resistance comparable to EC grade aluminum wires under many different types of corrosive conditions. This fact has been proven true by accelerated laboratory tests simulating industrial, marine, and tropical atmospheres. In addition to the tests, Alumoweld has proven itself as an electrical conductor in many utility installations; some in place for as long as 40 years.
Combines High Strength with Low Weight.
Alumoweld has a higher strength-to-weight ratio than other wires commonly used on overhead lines. It has eight times the strength of solid aluminum wire of the same diameter and only a little more than twice the weight. This high strength-to-weight ratio provides a maximum margin of safety for long-span construction. And, the high strength of Alumoweld's steel core is permanently protected by its thick aluminum covering.
