Description
This dataset is a market dataset, representing the consumption market of the region; the dataset includes the transport of the product from the gate to the consumer end, and the transport service is calculated according to the transport situation of this product in this region. The product represented by this dataset is an aluminium conductor steel-reinforced (ACSR) overhead conductor, which is an overhead transmission conductor composed of aluminium single wires spirally stranded around a steel central core, with an average weight of about 1.349 kg per metre, mainly composed of aluminium rod, galvanised steel wire or galvanised steel strand, etc., made through processes such as wire drawing, stranding and testing and inspection. The key upstream raw materials of this product are aluminium rod, wire drawing oil, aluminium wire, steel wire and lubricating oil, etc., and downstream it is mainly applied in the electrical energy transmission of high-voltage and ultra-high-voltage overhead transmission lines. In terms of system boundary, the packaging of the product and the transport, use, scrapping, recycling and final disposal after leaving the factory, as well as infrastructure such as the manufacture of production equipment and the construction of plant buildings, are not included within the dataset boundary. In terms of data sources and data processing, the data inventory is formed by merging data from multiple sources.
Activity Description
The system boundary is the cradle-to-gate of the steel-cored aluminum stranded overhead conductor. The starting point is the input of raw materials and the end point is the finished steel-cored aluminum stranded overhead conductor leaving the factory. The main stages include drawing (aluminum rod, drawing oil, etc.), twisting (aluminum wire, steel wire, lubricating oil, etc.) and testing and inspection.
Process Description
Overhead conductors are transmission conductors that use insulators to fix transmission conductors on towers standing upright on the ground to transmit electrical energy. They are more convenient to erect and maintain and less expensive. Steel-core aluminum stranded overhead conductor refers to an overhead conductor composed of one or more layers of aluminum single wires spirally twisted around a steel center core, with adjacent layers twisted in opposite directions; the middle part is a steel core, whose main function is to withstand various forces on the conductor, and the outer part is an aluminum stranded wire, whose main function is to transmit electrical energy. This product is in the form of a cable and is widely used in power transmission on high-voltage and ultra-high-voltage overhead transmission lines.

Technology comment
The production of steel-cored aluminum stranded overhead conductors mainly includes processes such as wire drawing, stranding, and testing and inspection. In the wire drawing process, aluminum rods are used as raw materials and drawn into aluminum wires using a wire drawing machine. The stranding process involves stranding the aluminum wires with galvanized steel wires or galvanized steel strands in equipment such as frame stranders to produce steel-cored aluminum stranded overhead conductors. After passing the required tests and inspections, the finished product is obtained.
