(Specification)Standard Specification for Concentric-Lay-Stranded Aluminum-Alloy 6201-T81 and 6201-T83 Conductors
Standard Specification for Concentric-Lay-Stranded Aluminum-Alloy 6201-T81 and 6201-T83 Conductors
ABSTRACT
This specification covers concentric-lay-stranded conductors, made from round aluminum-alloy 6201-T81 (hard: solution heat-treated, cold worked, and then artificially aged) wires, for use for electrical purposes. These conductors shall be constructed with a central core surrounded by one or more layers of helically laid wires. Conductors are classified as follows: Class AA (for bare conductors usually used in overhead lines) and Class A ( for conductors to be covered with weather resistant materials). The concentric-lay-stranded aluminum-alloy 6201 conductors sized to have diameter equal to ACSR, Class AA, and class A shall conform to the described construction requirements. The maximum electrical resistance of a unit length of stranded conductor shall not exceed the required nominal DC resistance. The concentric-lay-stranded aluminum-alloy 6201 conductors sized by standard areas, Class AA, and Class A shall conform to the described construction requirements. Minimum distance between joints in the complex and rating factors shall be described.
SCOPE
1.1 This specification covers concentric-lay-stranded conductors, made from round aluminum-alloy 6201-T81 (hard: solution heat-treated, cold worked, and then artificially aged) wires or 6201-T83 (hard: higher conductivity, solution heat-treated, cold worked, and then artificially aged) wires, for use for electrical purposes. These conductors shall be constructed with a central core surrounded by one or more layers of helically laid wires (Explanatory Notes 1 and 2).
Note 1: The aluminum alloy and temper designations conform to ANSI H35.1/H35.1[M]. Aluminum-alloy 6201 corresponds to Unified Numbering System alloy A96201 in accordance with Practice E527.
1.2 The values stated in inch-pound units or SI units are to be regarded separately as standard. The values in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
1.2.1 For density, resistivity and temperature, the values stated in SI units are to be regarded as standard.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
