Products Description
HMYDJ series insulating Mat voltage transformers use a single-frame core structure. The primary winding is wound on the core, and the high-voltage winding is outside. This coaxial arrangement reduces the leakage flux and increases the coupling between the windings. The product's outer shell is made to fit the core optimally, giving it an attractive, elegant appearance.
