Our pad-mounted transformers are engineered to provide safe, efficient, and reliable electrical distribution for medium-voltage networks. Designed for ground-level installation in tamper-proof, weather-resistant enclosures, they offer an ideal solution for urban, suburban, and industrial environments where underground power distribution is required.

Manufactured in compliance with IEEE C57.12.34 and IEEE C57.12.28 our transformers ensure superior safety, durability, and performance. They are available in three-phase configurations, with typical ratings from 700 kVA to 10000 kVA and voltage classes up to 34,5 kV.

Pad-mounted Transformers Features:

  • Dielectric Strength: High-grade insulation systems meeting IEEE and ANSI requirements.
  • Cooling System: KNAN cooling with environmentally friendly insulating fluids (FR3 natural ester fluid).
  • Protection & Safety: Dead-front and live-front designs with current-limiting fuses, bayonet fuses, pressure relief devices, and oil-level indicators.
  • Reliability: Hermetically sealed tank construction minimizing maintenance and protecting against moisture ingress. Efficiency: Low-loss core and coil design in compliance with DOE and IEEE efficiency standards to reduce energy losses and operational costs.

Our pad-mounted transformers are customizable to specific customer requirements, with options for advanced monitoring, smart grid integration, and eco-friendly fluids. Built to the highest industry standards, they guarantee long service life, operational safety, and superior performance in the most demanding applications.
