Three phase distribution transformers (with corrugated tubing)

Corrugated vat distribution transformers have a small footprint and an elegant design. These transformers are manufactured using the highest quality materials, using state-of-the-art and reliable manufacturing practices. These transformers require little maintenance. 

 

Advantages:

  • Compact size, corrugated wall transformers are smaller than heatsink transformers.
  • Improved heat dissipation.
  • Elegant appearance.
  • The fins have a sufficient degree of elasticity to cushion the expansion of the liquid volume due to heating of the cooling medium, while providing a large dissipation area to cool the cooling medium.
