In addition, the implementation of technologies such as nanocomposite has revolutionized insulation standards. Nanocomposites, which combine conventional materials with nanoparticles, have been shown to improve the thermal conductivity and mechanical strength of transformers. This approach allows transformers to operate at higher power levels without compromising their structural integrity, resulting in more efficient and longer operation.
Finally, it is important to mention the adoption of international standards in the manufacturing of these new materials. Standardization has allowed manufacturers to adhere to rigorous standards, promoting the reliability and quality of transformers. The following table illustrates some of these standards and their impact on the industry:

| IEC 60076 | Improvement in the quality and safety of transformers. |
| IEEE C57.12.00 | Increase in energy efficiency. |
| ISO 9001 | Ensures high-quality manufacturing processes. |
Impact of sustainable development on the choice of materials for transformers
Sustainable development has become a fundamental pillar in the electrical industry, especially in transformer manufacturing. The choice of materials is influenced by environmental, social and economic considerations that seek to minimise the negative impact on the environment. Today, companies are taking a more responsible approach to the selection of materials, prioritising those that not only meet the necessary technical specifications but also contribute to a more sustainable world.
Among the materials that have gained importance in this context we find:
- Recycled steel: Used in transformer structures, its use reduces the carbon footprint associated with mining and manufacturing new metals.
