Structure and characteristics
This series of voltage transformers features a pillar-type design and a fully enclosed epoxy resin casting process, offering excellent resistance to contamination and moisture, making them suitable for use in tropical regions. These transformers require no special maintenance, requiring only regular surface cleaning. The transformer's secondary terminals are equipped with a terminal box with holes on the front and side for safe and reliable wiring. Furthermore, the baseplate is equipped with a grounding bolt and six mounting holes for easy installation.
