Pauwels Trafo Ireland three phase pole mount transformers are used extensively in rural distribution networks in the UK and in many other countries.

The simplest tank design used is rectangular in shape with plain sides for the smaller ratings and very low loss types requiring less radiator surface. Corrugated fins are used to provide radiator surface for the larger ratings. Pauwels design and construction methods ensure that the mass is kept to a minimum for any given rating and loss level. This means that installation costs and pole loadings are also minimised. The HV outdoor shedded bushings for IEC types are located on the tank cover. LV bushings may also be on the tank cover or alternatively on the tank side. Standards applicable include IEC76 and ESI 35 - 1 as per client requirements. Arcing horns or lightning arresters can be fitted as required. ESI 35-1 standard requires that the HV bushings be angled as shown in this image.
