| Use advice for data set | The life cycle assessment of the reference flow SDC 12/17,5kV, an EEPS (Electronic and Electrical Products and Systems), is a “cradle-to-grave” analysis. The figure below shows the product life cycle stages and the information considered in the LCA. In terms of exclusions from the system boundary, according to Standard/PCR, capital goods such as machinery, tools, buildings, infrastructure, packaging for internal transports, and administrative activities, which cannot be allocated directly to the production of the reference product, are excluded. Infrastructures, when present, such as in processes deriving from the ecoinvent database, have not been excluded. Scraps for metal working and plastic processes are also included when already defined in ecoinvent. |
| Technical purpose of product or process | UniSec switchgear is used in medium voltagesecondary power distribution systems. It is ideal for use in transformer substations, for controlling and protecting feeders and power transformers, for infrastructure, airports, etc. UniSec is the ABB solution for a fully automated power distributionnetwork. |

| General comment on data set | Both primary and secondary data are used. The main sources for primary data are the bill of materials and technical drawings, while site specific foreground data are provided by ABB. Furthermore, information and data obtained from other LCA studies are also used. This includes the LCA of GSec (ABB document ID: 2RDA045546, rev. B) and the EPD of the Current Transformer TPU 43.13 (ABB document ID: 1VLG101084, rev. A). For all processes for which primary data are not available, generic data originating from the ecoinvent v3.9.1 database, “allocation, cut-off by classification”, are used. The LCA software used for the calculations is SimaPro 9.5. The utility consumption and waste generation at the ABB manufacturing site is allocated to the production of one reference flow SDC 12/17,5kV by using allocation rules. This is done by allocating electricity to surface area and production volume, heating and waste to surface area. Water is allocated directly to employees of the line involved in the study. For the end-of-life allocation, the “Polluter Pays” principle is adopted according to what is defined in the CEN/TR 16970 standard, as required by the PCR EPDItaly007. This means, waste treatment processes are allocated to the product system that generates the waste until the end-of-waste state is reached. The environmental burdens of recycling and energy recovery processes are therefore allocated to the product system that generates the waste, while the product system that uses the exported energy and recycled materials receives it burden-free. However, the potential benefits and avoided loads from recovery and recycling processes are not considered because it is not required by EPDItaly007. According to PCR EPDItaly007 “Electronic and electrical products and systems”, the cut off criteria can be set to a maximum of 2% of the overall environmental impacts. In this LCA, components like adhesive, glue and grease have been excluded as their weights are negligible. This same applies to packaging, where small parts such as sticking labels are even smaller fraction of the total mass. Surface treatments like tin plating, and painting have been considered in the LCA model. Black oxide and phosphate conversion coating (negligible usage) have been excluded due to the model complexity and unavailability of reference data. Scraps for metal working and copper transformation, considered as waste from the internal transformation process from raw material to finished product, were calculated and included in the LCA model. |
