Product overview

Design and operating characteristics

The transformer adopts a three-phase, double-winding, oil-immersed design with natural cooling and optional off-circuit tap adjustment. Depending on the project configuration, a fully sealed oil tank may be used to reduce contact between transformer oil and the external environment, helping improve operational stability and reduce routine maintenance requirements.

Large external cooling surfaces support reliable heat dissipation during continuous and fluctuating renewable-energy operation. Monitoring accessories such as oil temperature indicators, oil level indicators and pressure-relief devices can be configured according to transformer capacity and customer requirements.

Key features

  • Designed for photovoltaic, wind and energy-storage projects
  • Suitable for voltage systems up to 40.5kV
  • Fully sealed oil-tank configuration available
  • Natural cooling with efficient external heat dissipation
  • Suitable for fluctuating renewable-energy loads
  • Optional temperature, oil-level and pressure monitoring
  • Can be integrated into complete compact substation systems

Typical applications

Solar farms, wind farms, renewable-energy substations, distributed generation systems and medium-voltage grid-connection projects.
