1.Rated secondary current: 5A or 1A
2.Rated insulation level: 17.5/55/105 kV
Structure and characteristics
This series of current transformers is a pillar type structure, which is fully enclosed by epoxy resin, which is resistant to pollution and humidity. It is also suitable for use in tropical areas. The transformers do not require special maintenance. The secondary outlet terminals of the transformers are installed with waterproof connectors. There is a hole on the front and side of the terminal box, which is matched with the outlet end for wiring, which is safe and reliable. There are grounding bolts and four mounting holes for installation on the bottom plate of the product.
