    Structure and characteristics

    This series of voltage transformers adopt a pillar structure and are fully enclosed with epoxy resin by epoxy casting. They are resistant to pollution and moisture and are also suitable for use in tropical regions. The transformers do not require special maintenance; only regular cleaning of surface dirt is needed. Terminal boxes are installed at the secondary output terminals of the transformers. There is one hole on the front and one on the side of the terminal box to cooperate with the output terminals for leadout wiring, which is safe and reliable. There are grounding bolts and six installation holes for installation on the product base plate.
