The VUC types of on-load tap changers come in a range of models with ratings suitable for most applications. They are mounted inside of the transformer tank, suspended from the transformer cover. The VUC types operate with arc quenching in vacuum interrupters.
The VUC types complete the UC family of tap changers, with their excellent service record since the 1960’s.
The VUCG is the smaller of the VUC types and is suitable for transformers up to 800 MVA with a BIL rating of 1050 kV and current rating of 1800 A.
