1. What are the manufacturing standards for aluminum alloy cables?
In North America and other regions, aluminum alloy cables are primarily produced and inspected in accordance with ASTM B800-05 (2011), ASTM B801-07 (2012), C22.2 No. 51-09, and UL1569. Currently, the aluminum alloy cable standard implemented in my country is the energy industry standard "Rated Voltage 0.6/1kV Aluminum Alloy Conductor Cross-Linked Polyethylene Insulated Cable" (NB/T 42051-2015).
According to the website of the National Standardization Administration of China, the national standard "Aluminum Alloy Core Extruded Insulated Power Cables with Rated Voltages of 1 kV (Um = 1.2 kV) to 35 kV (Um = 40.5 kV)" (GB/T 31840-2015) was officially released on July 3, 2015, and will be implemented on February 1, 2016.
2. What are the international and domestic standards for aluminum alloy conductors?
1) International Standard: ASTM B800-05 (2011), Chinese Name: Standard for 8000 Series Aluminum Alloy Wire in Annealed and Intermediate Heat Treated Conditions for Electrical Use.
2) Domestic Standards: "Aluminum Alloy Wire for Cable Conductors" (GB/T 30552-2014), "Conductors for Cables" (GB/T 3956-2008), and "Round Aluminum Rod for Electrical Use" (GB/T 3954-2014).
3. What are the application standards for aluminum alloy cables?
Domestic standards for the application of aluminum alloy cables are relatively well established. These include the national industry standard (Code for Electrical Design of Residential Buildings) (JGJ 242-2011) and the "Code for Design of Store Buildings" promulgated by the Ministry of Housing and Urban-Rural Development.
National guiding standards and specifications, such as JGJ 48-2014 and the National Building Standard Design Atlas 10CD106 "Laying and Installation of Aluminum Alloy Cables," as well as local guiding standards and specifications, such as the "Code for Design, Construction, and Acceptance of Aluminum Alloy Cable Engineering," promulgated and implemented by provincial-level administrative departments such as the Department of Housing and Urban-Rural Development, have already acquired substantial guiding value.
