Each and every component of the HT transformer is manufactured and assembled with precision and utmost care. The main process lines of the transformers are: Core: The core is made with laminated and low loss electrical steel sheets that are imported, grain oriented, cold rolled and sheets of high-grade steel. The cores are assembled in a manner that they reduce the noise caused by vibration; individual stamping is coated with insulation varnish which is resistant to heat and oil on both sides. The core is connected to the clamp which ensures that it is effectually earthed. The core legs are bounded with heavy duty insulating tape. The yokes are rigidly and securely clamped between the folded steel channels. Clamps on top and bottom are firmly attached to each other by the means of tie rods. Tie rods serves the duel purpose of transferring the load from the bottom to the top clamps and securing the winding in place. This prevents tensile stress being setup in the core legs, which could adversely affect the iron losses.
