Introduction
Great progress has been made in the development and improvement of distribution transformers over the last decades.The application of high quality insulation material and suitable selection of the coil structure for high stress have contribute to the development of LS CAST RESIN Transformers. The LSCAST RESIN Transformer has succeeded in combining the advantage of oil-filled and conventional dry type transformers, which are fabricated with anepoxy resin. The windings are completely embedded under vacuum conditions.This casting method makes it possible to assure void-free epoxy penetration of both the inner layer and turn to turn insulation.

Application
LS CAST RESIN Transformers canbe used in various fields.Here are just a few possibleapplications.
● Indoor and outdoor unit substations
● Off-shore flatforms
● Commercial buildings
● Hospitals
● Shopping centers
● Water supplies
● Traction systems
● SCR Power supplies
