Analysis of the causes of traction electric failures of electric cargo cars operated on railways of the Republic of Uzbekistan

In this article, it is considered to analyze the reliability of TEM (traction electric machine) locomotives railways Republic Uzbekistan. To determine damage, most expedient and effective method will be extend life insulation by encapsulating local damage using impregnating materials heat radiation. Over past ten years, a stable tendency for breakdown turn-to-turn closure armature winding NB-514 type has been maintained in Unitary Enterprise (UE) “O'ztemiryo'lmashta'mir.” regard, hypothesis was put forward that breakdowns short-circuit often occur due intense mass exchange processes frontal parts their windings with open section heads.
