saudi arabia alfanar electric transformers introduction

General

  • alfanar offers a complete range of distribution transformers designed to grant reliability, durability, and efficiency required in utility, industrial, and commercial applications.
  • alfanar oil-immersed transformers are manufactured in accordance with the most demanding industry and international standards.
  • Transformer portfolio covers oil-immersed, pole mounted, pad mounted, unit/package substation three phase distribution transformers for distribution networks up to 10 MVA and 36 kV system voltages which can be used for indoor or outdoor applications.
  • Our main local clients include Saudi Electricity Company (Transmission and Generation) and private sector in Saudi Arabia, as well as international customers in Sudan, Ghana, Jordan, Ethiopia, Sharjah Electricity and Water Authority in UAE (SEWA) and Iraq.
  • Our local expertise has enabled us to work on turnkey projects such as Haramain High Speed Railway and King Abdullah Financial District.

Production

Core

  • The core of the transformers is built from laminated sheets of silicon steel alloy.
  • We use the Cold-rolled Grain-oriented electrical steel sheet (CRGO) M5T30 Core or laser treated silicon steel (H0).
  • It is cut on the most modern CNC core cutting machines for step lap construction.
  • The laminations are compacted and clamped together using yoke clamps or tie-bars locking the top and bottom yoke clamps together.

Winding

  • The windings of the transformers are made of high grade electrolytic copper.
  • The high voltage windings are wound either with round/shaped enamel or paper insulated wire.
  • The low voltage windings are wound with shaped, enamel or paper insulated wire or foil.
  • The winding construction is characterized by high dielectric strength with high resistance to atmospheric surges and to the effects of short-circuits.
  • Neutral points of the low voltage windings are brought to the tank cover.

Tank and painting

  • The transformer tank consists of the bottom plate, frame, and the tank sides.
  • The tank sides are made of corrugated panels in order to increase the total cooling area.
  • Corrugated panel welding is done by a welding robot ensuring a consistent and leak proof weld.
  • Tanks are shot blasted and leak tested.
  • Final painting process includes shot blasting and thorough cleaning before applying the liquid/flood painting with shade color RAL 7033/7035 or as per the customer requirements.
  • Our painting system has successfully passed 1000hrs salt spray (fog) test as per ASTM B-117 and evaluated as per ASTMD-1654-procedure A and adhesion test as per ASTM d-3359 Method B.

Assembly and Processing

  • Insulating cylinders are placed around the core to provide the required insulation from the low voltage winding. Complete windings are supported on the bottom yoke with the help of a bed of spacers. Pressing of the winding is achieved by using vertical tie rods whereas the core bottom and upper yoke is pressed with the help of horizontal tie rods.
  • Upon completion of its assembly, the core coil is dried. Oil filling is done under vacuum conditions in order to ensure full and reliable impregnation of the insulation materials free of air voids. Then will guarantee increased high voltage withstand strength. The drying and degassing process of the oil is controlled automatically.
