Improvement of Mechanical Performance of Large Capacity Dry‐Type On‐Board Traction Transformer Under Short‐Circuit Electromagnetic Force

High Voltage, Volume 10, Issue 6, Page 1558-1570, December 2025.
ABSTRACT The application of dry‐type on‐board traction transformers (D‐OBTTs) aims to achieve lightweight electric multiple units (EMUs) and support the approach for carbon neutrality. However, the production of large capacity D‐OBTTs are limited due to the defects in insulation materials under the impact of short‐circuit electromagnetic force.
