Dry Type Split winding transformer refers to a multi winding power transformer composed of one high-voltage winding and two or more low-voltage windings with the same voltage and capacity per phase. The normal power transmission of split transformers only occurs between high and low voltage windings, and in the event of a fault, it has the function of limiting short-circuit current.

Features of Dry Type Transformer Split Transformer with Multiple Windings
Robust Dry Construction: Adopting a dry design with high insulation level and dust-proof and moisture-proof ability.
Maintenance-free and fire-safe: Without oil, so there is no risk of fire in oil immersed transformers, and there is no need for routine maintenance and oil replacement operations.
Split Winding Capacity Equivalence: The total capacity of each split winding in a dry-type split transformer is the rated capacity of the split transformer. Usually, the low-voltage winding is divided into two or three branches as a split winding, with the line end marked with lowercase letters and numbers. The non-split high-voltage winding is composed of two parallel branches, with the line end markings unchanged. The total capacity of each split winding is the rated capacity of the split transformer.
