Description

Advantages

  • Low Maintenance: Cast Resin Transformers require only occasional visual inspections. No oil sampling or Doble testing of bushings is required.
  • Eco-Friendly: No oil in the design, making them ideal for environmentally sensitive areas.
  • Safety: Flame-retardant, self-extinguishing, and produces no toxic by-products.
  • Very High Short-Term Overload Capacity: Resin and fiberglass encapsulation provide superior overload capability.
  • Space Savings: Compact design eliminates oil containment structures, fire suppression systems, and coolers.
  • Low Noise Levels: Compact construction results in lower operating noise.
