The large transformers manufactured in this industrial process are designed for deployment within wind power generation facilities. Specifically, these transformers are suited for integration into substations associated with wind farms that utilize 1.5 megawatts (MW) wind turbines. These transformers are essential components for stepping up the voltage of generated electricity to levels suitable for long-distance transmission and distribution within power grids. When utilizing the life cycle inventory data on the manufacture of the large transformers, users should ensure that the system boundaries are compatible with the intended scope of the LCA study. This data should reflect the energy consumption and pollutant emissions during the production phase of the transformers, as specified by Xue et al. (2015). Users should consider the environmental impact and substitution effects of these transformers within the broader context of a wind power generation system as demonstrated in the case study of a 1.5 MW wind turbine-equipped wind farm in the northeast of Inner Mongolia. Assumptions based on data collected from Wang (2012) and Xia and Song (2017) should be critically assessed for current validity and relevance to the specific LCA application.
