ASTM B173-17 用于电导体的具有同心绞合构件的绳布绞合铜导体的标准规范

1.1 This specification covers bare rope-lay-stranded conductors having concentric-stranded members made from round copper wires, either uncoated or coated with tin, lead, or lead-alloy for use as electrical conductors (Explanatory Note 1 and Note 2). 1.2 Coated wires shall include only those wires with finished diameters and densities substantially equal to the respective diameters and densities of uncoated wires. 1.3 The values stated in inch-pound or SI units are to be regarded separately as standard. Each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. For conductor sizes designated by AWG or kcmil, the requirements in SI units have been numerically converted from corresponding values, stated or derived, in inch-pound units. For conductor sizes designated by SI units only, the requirements are stated or derived in SI units. 1.3.1 For density, resistivity, and temperature, the values stated in SI units are to be regarded as standard. 1.4 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.

Standard Specification for Rope-Lay-Stranded Copper Conductors Having Concentric-Stranded Members, for Electrical Conductors

ASTM B1006-17 电气架空导体代码字名称的标准规范

1.1 This specification lists code word names for bare overhead electrical conductors that are recognized in North America. A procedure has been outlined for adding additional code word names to this standard. Code word names have been in existence for many years describing various conductor constructions used in North America, Europe and elsewhere in the world. Their origin is not clearly understood. The historical basis of this standard originates from code word names developed years ago by member utility companies that participated in the US Aluminum Association, Technical Committee. 1.2 The code word names are grouped into tables of like constructions. The code word name construction can be modified with the use of suffix modifiers that identify additional construction variations. For example the type of steel core material used in an ACSR type of conductor may be modified with the letter designation “/GA3” denoting the strength and type of coating for the steel core material. 1.3 The tables provide the applicable ASTM standard for which the conductor construction may be built to. For conductors that are unique to use in Canada, the applicable CSA International standard is referenced. 1.4 The tables include code word names that are referenced in Canadian CSA and European CENELEC standards. The information is believed to be correct however the user of this document is encouraged to consult the applicable CSA or CENELEC standard for confirmation. 1.5 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.
