The LFD traction transformers drying machine developed by Globecore is designed to remove moisture from transformers used in railway, tram and metro power grids, with the aim of extending their life, improving their insulating properties and preventing emergency shutdowns. LFD applies thermal vacuum drying technology, which is said to be effective in removing moisture from oil and transformer windings.It is understood that under conditions of constant loads, vibrations and temperature fluctuations, moisture can gradually reduce the insulation performance of the equipment. It is hoped that regular drying will help to avoid breakdowns, overheating and reduced efficiency of transformers. The LFD’s compact design and ease of operation could make it a universal solution for railway transport companies and municipal power grids, and the unit can be easily connected to transformers of different capacities, operates automatically and requires minimal maintenance.
