    Abstract

    This specification covers round, grooved, and figure-9 deep-section grooved bronze trolley wire. The bronze trolley wire shall be made in any of the three distinct alloys indicated in accordance with their increasing conductivities: Alloy 40, Alloy 55 and Alloy 80. Tensile tests and tension tests shall be performed wherein the wires shall conform to the required values of tensile strength and elongation. Twist tests shall be performed wherein round wires shall conform to the required number of twists. The specimens shall also connform to the required values of electrical resistivity.
