They are made of copper or aluminum. Low-voltage windings are made of strip or flat wire while high voltage windings are manufactured from round or profile wire. ("diamond-dotted paper") bonds the winding into a compact block while drying and increases the short-circuit capacity additionally. Magnetic Core lamination.The three-limb iron core is made of oblique cut Grain-oriented, seven-step silicon steel lamination insulated on both sides, guaranteeing low losses and low noise. These values are even improved by laser treatment. It is protected on the surface with a flash-proof varnish in order to prevent the sheet from corrosion and to reduce the noise. Oil tank.Whether during transport or operation -the tank must be absolutely tight under mechanical stress. We have vast constructional experience, the most modern calculation methods and high-quality welding work. Special attention is paid to corrosion protection. Pretreatment of the surface is processed by phosphating pickling, contributes to corrosion protection, just like multi-coating with preset drying times for each layer. On request, hot-dip galvanization provides for even better protection Test labTesting are conducted for every transformer before delivery.Tests are classified to be routine tests and type test. A - Routine tests: According to IEC 60076 standard , the following tests must be carried out for all units of the transformers a- Measurement of winding resistance . b- Measurement of voltage ratio and check of phase displacement. c- Measurement of short circuit impedance and load losses. d-Measurement of no-load losses and current . e-Dielectric routine tests including the separate source AC voltage withstanding test and short duration induced over voltage withstanding test ( ACSD ) . B - Type tests : The following tests shall be carried out a- Temperature rise test b- Lightning impulse test C - Special tests : a- Determination of noise level according to IEC 60551 . b- Short Circuit Dynamic stability Test (test report from independent and accredited laboratory for similar transformer will be accepted).
