S13-M Oil Immersed Distribution Transformer for 10kv / 20kv Power Systems

S13-M Oil Immersed Distribution Transformer for 10kv / 20kv Power Systems. S13 no-load losses are reduced by over 25% compared to S11. The 3D wound core structure further reduces noise by 5-8 dB(A), saving electricity and cost over long-term operation. The corrugated tank features a fully sealed structure, isolating the oil from air to slow down aging. Under normal operation, no oil replacement is needed, significantly reducing maintenance costs. Windings use high-quality oxygen-free copper with balanced ampere-turn distribution and low leakage flux. The core and coils are firmly clamped as a whole to withstand short-circuit current impacts.
