SH15‑M Amorphous Alloy Oil‑Immersed Distribution Transformer
The SH15-M series is a fully sealed oil-immersed distribution transformer featuring an amorphous alloy core designed for high energy efficiency.
Amorphous alloy has an ultra-thin domain structure, low magnetizing power and high electrical resistivity. Compared with conventional silicon-steel transformers, the no-load loss of the SH15-M series can be reduced by up to 70%, making it particularly suitable for applications where transformers operate under light-load conditions for extended periods.
The fully sealed corrugated tank helps prevent air and moisture from entering the transformer, reducing oil degradation and supporting maintenance-free operation. The series is suitable for power grid upgrading, renewable energy projects and continuous light-load distribution applications.
