These dry-type 3-phase distribution transformers are open coil/core ventilated, NEMA 3R (outdoor enclosed) rated that offer significant energy savings and environmental benefits. They are rated up to 75 kVA, and the standard 10 kV BIL rating (Basic Insulation Rating) provides increased reliability and protection against critical equipment failure including protection against voltage spikes and other line transients. Standard advanced core and coil construction features save installation labor and materials. The core is manufactured from quality non-aging, cold-rolled, silicon steel laminations and precision cut to close tolerances, which eliminates burrs and improves performance. The core is coated to prevent the ingress of moisture and precision wound aluminum conductors are electrically balanced to minimize axial forces during short-circuit conditions.
