CG Power Systems produces several thousand single phase pole mount transformers every year. Single phase pole mount distribution transformers are used mainly in the United Kingdom and Ireland, where some suburban and rural electricity distribution is by single-phase overhead lines to sites close to consumers. The simplest basic tank design used is the cylindrical tank configuration with HV outdoor shedded bushings on the tank cover and LV bushings also on the tank cover or alternatively on the tank side. Arcing horns or lightning arresters can be fitted as required.
