C.T.S. (Special Transformers manufacture) manufactures custom built transformers to meet any customer's requirements and the production covers all the application fields of dry – type transformers up to 500 kva. Manufacturing process is divided in the following steps:
transformer calculation/inductance and dimensional drawing
connections and initial inspection
polyester resin impregnation ( H class)
surface finishing, final inspection and strenght test
When coil winding is made directly on the core we use H class angle brackets internally manufactured.
Coil windings are made both in copper and in aluminium: all the aluminium transformers are Tig welded fillet
Calculation and manufacture in according to CEI EN 60742 standards about dry-type transformers production
