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.
• Designed for Harsh Environments: Maximum protection against moisture, particulates, pollution, salt, and harsh weather conditions.
