Core , which is the main element of transformers and defined as the core; It is produced from magnetic silicon steel plates whose grains are oriented. We realize the core production by using conventional or high magnetic permeability (HB) material, depending on the features of the project.


Cylindrical / elliptical coils are used in power and distribution transformers, which are more resistant to forces occurring during short circuit. Except for HV coils of small type distribution transformers, LV and HV conductors are used, using insulation materials with high insulating properties, It is isolated in wire insulation machines.

In power transformers, layer winding, overturned respect, radial channel winding, etc. Various winding shapes are applied such as.


Boiler and cover production of power and distribution transformers are carried out within our factory, except for radiators and corrugated walls. Boilers and covers are produced with high quality in a short time with our modern machinery in accordance with the drawing and technical values ​​of the project.


After the transformer boilers have passed the test procedures successfully, they are removed from oil, dirt, dust and metal residues to strengthen the contact of the paint with the metal surface. needs to be cleaned. For this, the boilers and all metal parts are subjected to sandblasting.

Metal parts are painted with one or more layers of special protective primer paint. Transformer boilers will be exposed to difficult weather conditions for many years As it is known, it is painted using a special paint with a thickness of at least 105 microns that can resist these difficult conditions.

Components that make up the transformer active part are combined in the assembly section. Coils are placed in the cores. Commutators, bushings and all connections performed. Some parts are insulated against possible overvoltages. In order for the active part to be durable in terms of mechanical strength It is fed with additional supplements. The active part whose assembly process is completed is subjected to the drying process in a solvent vapor vacuum oven. Classic drying process is 5 times longer than the drying time in the solvent vapor vacuum oven. Long time, transformers ages the insulation materials used. The short drying time in the vacuum oven with solvent vapor causes the insulation to age. constitutes an obstacle.

During the process, unwanted materials such as oil, dirt, dust, rust in the whole transformer are cleaned with solvent sprinkling. The use of solvent vapor furnaces capable of high vacuum in the production of hermetic and power transformers is very important in terms of product quality.
