S11 10/0.4KV Oil Type Power Transformer GB/T25446 Standard
Product Introduction
This type is a combination of our company's research and
application of new materials and new processes, independent
innovation and technology introduction, and through the
optimization and innovative design of the core and coil structure,
to achieve the purpose of reducing no-load loss and noise.
Independently developed products.
Compared with the current national standard JB/T10088-2004, the
noise level has dropped by an average of 20%, and the product
performance level has reached the domestic advanced level.
