Scope

Scope: This standard specifies the product models, requirements, test methods, and inspection rules, as well as the packaging and marking, transportation, and storage of aluminum-clad iron-core heat-resistant aluminum alloy strands (hereinafter referred to as strands). This standard applies to the design, production, and acceptance of aluminum-clad iron-core heat-resistant aluminum alloy strands used in overhead transmission lines; Main technical content: The main technical parameters of this standard refer to the national standards GB/T 1179-2017 "Centralized Twisted Aerial Conductors of Round Wires" and GB/T 20141-2018 "Centralized Twisted Aerial Conductors of Profiled Wires", and are drafted in combination with the current actual situation of aluminum-clad iron-core heat-resistant aluminum alloy strands. Aluminum-clad iron-core heat-resistant aluminum alloy strands achieve a doubling of the transmission capacity of steel-core aluminum strands with the same cross-section by combining heat-resistant aluminum alloy wires and aluminum-clad iron-core wires, without significant changes in sag. They have been widely used in overhead transmission line capacity-upgrading projects at home and abroad. At present, no relevant technical specifications have been found at home and abroad, which has brought certain constraints to the manufacture or procurement of aluminum-clad iron-core heat-resistant aluminum alloy strands. The formulation of the group standard "Aluminum-Clad Iron-Core Heat-Resistant Aluminum Alloy Strands" will effectively guide domestic enterprises in the development and production of such products, and also provide an important basis for users' procurement and acceptance. At the same time, it will be conducive to standardizing and leading the application and development of such products in the field of overhead transmission lines.
