S 1 1 What are the technical parameters and requirements of the transformer and the national standards?

S 1 1 Transformer: The fully sealed distribution transformer with wound core is a new generation of low noise and low loss transformer developed in recent years. Its core is seamless, which greatly reduces the no-load loss and no-load current, and the no-load current is reduced by 60%~80%. The high and low voltage coils are continuously wound on the iron core, and the windings are compact and concentric, which further enhances the anti-theft performance of the product.
