Pillar type indoor current transformer

General:

This type of transformer is an epoxy resin cast completely closed structure, its core is made of microcrystalline alloy or high-quality magnetic conductive silicon steel sheet wound into a ring, the secondary wire evenly wound on the top, the product is equipped with 3-4 secondary winding, with high performance and high parameter characteristics. The primary conductor is wrapped with reinforced insulation to avoid short circuit between turns. Ground bolts and mounting holes are provided on the base plate.
