Hy-Bute-60® Instrument Transformers - Your Foundation for Superior Metering and Protection

GE has been in the Instrument Transformer business for decades. The distinguishing feature in the GE product line is its Hy-Bute insulation. The Hy-Bute-60 molded insulation has been proven to be a steady and reliable technology. While other insulation materials have come and gone, GE's Hy-Bute-60 molded butyl has become the standard for durability by which all others are measured. Our timeless durability results in a lower total cost of ownership for our customers.
