Transformers are used to supply power from an AC source to devices operating at different voltages. This transformer is designed for use in low-voltage applications and has an average weight of approximately 55 g. The dataset includes key raw materials, energy inputs, atmospheric emissions, and waste generated during the production process. Infrastructure such as manufacturing equipment and facility construction is not included within the system boundary of this dataset. The life cycle inventory is compiled from data sourced from multiple references. Transformer manufacturing involves several process steps, including winding, corner cutting, stripping, testing, gluing, drying, soldering, impregnation, baking, secondary testing, angle correction, taping, and marking.
