K-factor transformer also named as K-factor rating transformer or K rated transformer, could be applied in the non-linear load electrical circuit, K-factor is a weighting of the harmonic load currents in the light of their effects on the heating of the transformer. Sometimes people also call it as UL certificated transformer since it has UL certification.

Shinenergy’s 250KVA transformer is one kind of dry-type transformer, which is used to step down the high voltage to a lower level, the main function is to protect the utility in the electrical circuit and the operating person. It could be divided into single phase transformer and three phase transformer according to different applications.

Shinenergy’s control transformer could be used to step down or step up the voltage, sometimes we also call it a step down transformer or step up transformer, widely applied in the electric circuit requires low power or volt-amp rating. Control transformers could provide voltage regulation and convert high or low voltage for different application requests. Control transformers could be divided into single-phase and three-phase transformers according to different applications.
