The LFD subway transformers drying machine developed by Globecore has been designed with the intention of removing moisture from transformers used in underground environments, with the aim of helping to extend the life of electrical devices by improving their insulating characteristics and reducing the risk of accidents.LFD uses thermal vacuum drying technology that effectively removes moisture from transformer windings and oil, which is particularly important in metro areas, where high humidity and temperature fluctuations accelerate the aging process of insulation and lead to deterioration of equipment performance. The compact and mobile design of the LFD makes it convenient for operation in the difficult conditions of underground facilities, and the unit can be easily connected to transformers of various capacities, operating in automatic mode and requiring minimal maintenance.
