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 and only need to have their surface dirt cleaned regularly. A terminal box is installed at the secondary output terminal of the transformer. There is a hole on the front and a hole on the side of the terminal box to cooperate with the output terminal for lead-out wiring, which is safe and reliable. The base plate of the product is equipped with grounding bolts and four installation holes for installation.
