Abstract

This guide covers standard specification for high-strength, extra-high-strength, and utilities grades of concentric lay steel wire strand composed of three wires or seven wires with Class A, Class B, or Class C zinc aluminum-mischmetal (Zn-5 Al-MM) alloy coatings specifically intended for use as overhead ground wires or static wires for electric power transmission lines. Alloy-coated steel wires, of varying sizes and grades of strand, shall conform to the specified values of the approximate weight per unit length of strand and the minimum breaking strength of the finished strand. The weight of the three classes of coating shall not be less than the specified value. The steel wires shall meet the required mechanical properties such as breaking strength, elongation, and ductility.

Scope

1.1 This specification covers high-strength, extra-high-strength, and utilities grades of concentric lay steel wire strand composed of three wires or seven wires with Class A, Class B, or Class C zinc-5 % aluminum-mischmetal (Zn-5 Al-MM) alloy coatings specifically intended for use as overhead ground wires or static wires for electric power transmission lines.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
