    With huge industrial experience and skills, AL ADWANI  transformers presents different range of dry type transformers in Saudi Arabia. We are manufacturing dry type transformers in India for our clients in Saudi Arabia, other Middle East countries and Africa.  We are glad to introduce ourselves as one of the renowned manufacturers, exporters and whole sale dry type transformer supplier in Saudi Arabia.

    Due to its high reliability, fire resistance, maintenance free, higher short circuit strength, overload capacity our dry type transformers has become one of the prime choice of every clients.

    Main advantages of dry type transformers

    1.     No fire hazard

    2.     Maintenance free

    3.     Can be located closer to the electrical load

    4.     Echo friendly

    5.     Ease of installation

    6.     Higher life time

      Manufacturing process


      Three limb core construction is used. Core sheets are made from cold rolled grain oriented (CRGO) silicon steel sheets. Fibre- glass tape banding hold the core tight and reduce the noise level. Treatment given to the completed core protect it from atmospheric corrosion.


      Both the HV and LV windings are made from copper conductors. On the LV side copper foil is used depending on current to be carried.

      The advantages of these windings are reduction of  extra losses, balanced temperature distribution within the winding and high short circuit capability.

      On the HV side, this is the heart of dry type transformers. The production of HV applications only using vaccum-encapsulated moulds. The interconnection between HV phases are obtained by links made out of copper tubes with their ends  formed into lugs.


      Protection against overload or high winding temperature can be provided by thermistors. Alarm and trips are also provided. 

      An ISO-9001 : 2008  certified company has over 25 years of experience in the manufacturing of transformers. The transformers are built in accordance with IS2026/IS 11171 and IEC 726bstandards .We have been audited and have passed many detailed in depth quality audits conducted by respected third party agencies. We are producing dry type transformers to meet our client’s demands. The assurance of providing world class quality is our primary goal.

      We don’t accept compromises when it comes to conservation and employment protection and set standards for the construction of transformers. Our integrated management system(IMS) ensures the effective conversion of our own claims as well as the official requirements.

      Our commitment is to satisfy each customers individual needs with a high quality, custom designed transformer while maintaining the shortest lead times in the industry.

      Routine testing

      The required routine tests are carried out in plant by trained personnel using modern, calibrated digital test equipment.

      These tests include

      • Ratio and vector group
      • Insulation resistance
      • Applied voltage
      • Induced overvoltage
      • No load loss
      • Full load loss
      • Impedence
      • Partial discharge
