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 a tank-type SF6 circuit breaker, which is an SF6 circuit breaker that uses a metal casing to fully enclose the internal core components and uses SF6 gas as the arc-extinguishing medium, with a single-unit weight of about 4049.365 kg and an average nominal voltage of 127.5 kV, mainly made from components such as steel, stainless steel and plastic, and copper parts, insulating materials and SF6 gas, through processes such as component processing, assembly, SF6 gas filling and testing. The key upstream raw materials of this product are steel, stainless steel, plastic and copper parts, insulating materials and SF6 gas, etc., and downstream it is mainly applied in high-voltage and ultra-high-voltage power systems, especially in the control and protection of outdoor substations and large power plants. 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.
