The 10kV class S(B) H15 series amorphous alloy distribution transformer represents a leap forward in energy-efficient power distribution technology. Engineered with a core of advanced amorphous metal, this transformer series is designed to achieve ultra-low no-load losses, significantly reducing electricity waste and operational costs. Ideal for utility grids, commercial complexes, and industrial plants, the S(B) H15 series offers exceptional reliability and a rapid return on investment by minimizing the total cost of ownership over its entire lifecycle. It sets a new standard for eco-friendly and economically viable electrical infrastructure.
Features an H15 grade amorphous alloy core that reduces no-load losses by 60-80% compared to conventional silicon steel transformers, translating directly into lower electricity costs.
Ultra-low no-load losses ensure the lowest total cost of ownership over its entire service life, offering an excellent return on investment despite a slightly higher initial capital outlay.
Drastically reduced energy consumption leads to a lower carbon footprint. As a dry-type transformer, it is oil-free, flame-retardant, and explosion-proof, making it safer and more environmentally friendly.
The amorphous core is inherently resilient to mechanical stress and offers strong short-circuit resistance. An optimized magnetic circuit design ensures quiet operation below standard limits, suitable for noise-sensitive areas.
Designed and manufactured in compliance with international standards (IEC, IEEE) and relevant Chinese National Standards (GB), guaranteeing global applicability, reliability, and high quality.
