Toroidal transformer-9

Products Information

Toroidal Transformer
Our toroidal transformer cores are manufactured from a continuous strip of high grade steel, there are no air gaps and loose sheets of steel or laminations to cause vibration. This stability is further enhanced by the copper windings of the toroidal power transformer which tightly surround the entire circumference of the core.
