Overview

The core design philosophy prioritizes product reliability and enhanced performance. During development, we recalibrated loss parameters and structural configurations in accordance with practical operating conditions of modern power equipment, so that calculated loss figures closely match measured test values.

The product adopts optimized structural design with a well-balanced copper-to-iron material ratio, which minimizes raw material costs while delivering a more compact and rational mechanical structure.

Note 1: For transformers rated 500 kVA and below, load loss figures above the slash apply to Dyn11 or Yzn11 vector groups, while those below the slash correspond to the Yyn0 vector group.

Note 2: When the transformer’s annual average load factor ranges from 35% to 40%, the loss values listed in the table deliver maximum operational efficiency.
