TANK FABRICATION

Protection of active part in transformer is very important. While achieving the opti-mized size of transformer to suit the site condition for installation. The main role of the tank is to protect the active part and tank is manufacture to have sufficient strengths to withstand internal & external faults that may occur during operation. Tanks are fabricated from low carbon M.S. Sheet of best quality proceed by qualified welders. The tank is designed to withstand vacuum and pressure test as per national/ International standards. A robust skid un-der base is provided, and guide bars are located inside the tank to securely fix the core and windings assembly in position, and to prevent any movement during trans-portation.

CORE COIL ASSEMBLY

The core assembly is vertically placed with the foot plate touching the ground. the top yoke of the core is removed. The limbs of the core are tightly wrapped with cotton tape and then varnished. Cylinder made out of insulating press board/ pressphan paper is wrapped on all the three limbs. Low Voltage Coil is placed on the insulated core limbs .Insulating block of specified thickness and number are placed both at the top and bottom of the L.V.Coil .Cylinder made out of corrugated paper or plain cylinder with oil ducts are provided over L.V.Coil. H.V. Coils are placed over the cylin-der .Gap between each section of H.V. Coils including top & bottom clearances is main- tained with the help of oil ducts, as per the de-sign/drawings. The Top Yoke is refilled. Top core frame including core bolts and tie rods are fixed in position. Primary and secondary windings are con-nected as per the requirements. Phase barrier be-tween H.V. phases are placed as per requirement.



CONNECTION

After necessary testing the winding connections are completed. The tapping connections are made with the tapping switch. The three phase windings are connected in delta or star according to require-ments.



LAB TESTING FACILITY

Testing facilities are fully equipped to carryout all pre-scribed routine tests on the Transformers Manufactured. We encourage our clients in the private sector to witness final testing of their equipment and keep them intimated on the testing dates. Arrangement s for any special test s at the discretion of the client are also made after agree-ment on the costs involved, if not mentioned in the pur-chaser/ work order.
