Description

Product introduction
Foil winding technology is adopted in the PV inverter grid-connected transformer winding and full-joint structure in the iron core. As the material of iron chip, silicon steel strip is low loss oriented and has the advantages of low loss, high efficiency, low temperature rise and so on. This transformer is suitable for the circuit of AC *0Hz/*0Hz and the voltage no more than **0V(rated voltage), The technology of this product has reached the domestic leading level. And it can be designed and manufactured depending on customers requirements
