On-load tap changers type VUBB

The VUBB type of on-load tap changer is designed for mounting inside of the transformer tank and is intended for transformers up to 100 MVA. It is extensively tested even beyond what international standards stipulate which—together with experience from tried and tested solutions—ensures the dependability of the product. Simplistic, reliable design philosophy ensures less complexity for reduced maintenance time and cost.

Product scope

  • Base technology: Vacuum, resistance, in-tank, selector switch
  • Common applications: Network, special, industrial

Why Hitachi ABB Power Grids?

  • Savings in transformer space. Completely self-contained cylindrical design ensures reduced transformer size and ease of installation.
  • Integrated pre-selector eliminates gassing in the transformer tank and the resulting error in gas analysis.
  • Our patented system for field inspection without disassembly exemplifies the simplistic, reliable design philosophy for ease of use.
  • Reduction in maintenance costs. No changing of wear parts during the transformer’s lifetime with normal operation.
