The set of nondestructive test equipment for diagnostic test of contact line supports

The destructions of railway contact line supports, and other constructions, are complicated chemical-physical irreversible processes. Building material nature causes the inevitability of destructions. Fault detection of indications of carrying capacity decrease (cracks and others) by simple visual inspection sometimes is very difficult and even impossible as defects may be hidden inside constructions. In this paper, nondestructive test equipment sets for the diagnostic testing of electric railway contact line supports are presented by the authors.
