SF11-20000-26600/24.9/4.16 Transformer

SF11-20000-26600/24.9/4.16 Transformer

Daelim Transformer's SF11-20000-26600/24.9/4.16, is a meticulously designed three-phase transformer manufactured in accordance with the esteemed IEEE C57 standard. This exceptional 20 MVA transformer has been specifically tailored for installation in Houston, USA, and holds the prestigious UL listing.

Daelim Transformer's 20 MVA 24.9/4.16kV Vector Group Dyn1 3 Phase Step Down Oil Immersed Substation Transformer boasts enclosed terminals on both the low voltage (LV) and high voltage (HV) sides. The transformer employs the efficient KNAN/KNAF cooling system, ensuring optimal performance. At a temperature of 65°C, the power rating according to KNAN is 20 MVA, while it reaches 26.6 MVA with KNAF. The 20 MVA transformer exhibits an impedance of 8% at 65°C.

The environmental conditions of the installation site are carefully considered, with a maximum ambient temperature ranging from -25°C to 35°C. The primary winding operates at a tension of 24.9 kV, while the secondary winding operates at 4.16 kV. Our transformer utilizes high-quality copper winding material, providing superior conductivity. The primary winding is connected in the delta (D) configuration, while the secondary winding is connected in a wye (YN) configuration. As for the insulating oil, we employ FR3 brand vegetable oil, which is free from PCB.
