Cast resin type dry power transformer
Cast resin type dry power transformer
Application
The product of this latest series are resin cast transformers reinforced by glass fiber grid. Resin is fed by flow control pump and static control in order to prevent coils from alligator crack. The advanced cast technique ensures the resin mixture fully immerses into the space between turns and segments in order to ensure the dielectric strength and minimum partial discharge(≤5PC).
