Guided by dual-carbon goals, the construction of new power systems continues to advance. Energy conservation, carbon reduction, and green low-carbon development have become the core orientation of power equipment development. Low-loss, high-efficiency, and environmentally friendly energy-saving transformers are experiencing a wave of widespread adoption, gradually replacing traditional high-energy-consuming equipment and becoming the mainstream choice for power grid construction, new energy projects, and industrial power distribution, thus contributing to the energy conservation, emission reduction, and green transformation of the power system. As a core device in the power transmission process, transformer operating losses are a significant component of power system energy consumption. Traditional, outdated transformers have high energy consumption and serious resource waste, generating substantial ineffective energy consumption over long-term operation, which does not meet the requirements of green and low-carbon development.

To promote energy conservation and carbon reduction in the power sector, power departments and industrial enterprises across the country have continuously carried out special replacement and renovation projects for old transformers, comprehensively eliminating outdated high-loss equipment of S11 and below, and promoting the mass production of high-efficiency energy-saving transformers such as S13 and S15 series, as well as new energy-saving equipment such as amorphous alloy transformers. Compared with traditional products, new energy-saving transformers significantly reduce no-load losses and load losses through optimized core structure, upgraded core materials, and improved production processes, resulting in significant overall energy-saving effects. Data shows that the annual energy consumption of a single new energy-saving transformer can be reduced by more than 20%. Large-scale replacement can effectively reduce the overall energy consumption of the power grid and improve the efficiency of power energy utilization.

In addition to power grid upgrades, energy-saving transformers are also being widely adopted in new energy power plants, industrial parks, commercial complexes, and rail transit. New energy wind and photovoltaic power plants, relying on energy-saving transformers, can effectively reduce power transmission losses and improve the efficiency of new energy absorption. Industrial plants can reduce production electricity costs through equipment replacement, helping enterprises achieve energy conservation and carbon reduction goals. Industry standards are constantly being updated, further raising the energy efficiency threshold for transformers and forcing companies to accelerate product upgrades and iterations. Major manufacturers are continuously increasing investment in energy-saving technology research and development, constantly optimizing product energy efficiency indicators, and exploring the application of green and environmentally friendly insulation materials and halogen-free flame-retardant materials to promote the green and low-carbon transformation of transformer products throughout their entire life cycle, contributing to the high-quality construction of new power systems.
