Characteristics
*Energy saving: amorphous core would reduce no-load losses
*Adopt amorphous alloy as the core’s material, no-load loss is lower 65% than S11
*Security: strong ability of withstand short-circuit in the low voltage coil
*Low voltage winding wound on the hard paper tube, enhancing the capacity to withstand short circuit for the transformer
*Easy: maintenance-free
*Adopt high quality anti-aging seals, ensure the transformer maintenance free
*Three- column structure: could joint into Yy0, small
*The 3 column core, winding connection symbol can be Yy0 .
