Current Transformer (mold/dry types)

Current Transformer (mold/dry types)

Overview

Current Transformer for high voltage.

We have ultra-precise current transformer for measurement of microscopic/large (0.6/2000A) current and for protection with low burden.
We will manufacture window type current transformer for high voltage/extra high voltage and for bus-bar at very low cost.

With your inquiry, we will design and manufacture product which is not available in list below.
