At the beginning of the sixties Giorgio Pedroncelli began to manufacture elecrtic air-core transformers single-three phase up to 100KVA power and working voltage up to 10KV. From 1985 his sons joined and supported him in the study and development of new products and processing. Over the years the company, despite the size and concept of small industry, built its structure to meet the demand of its customers. Nowadays TRASFEM Srl has a flexible capacity and can manufacture quite large productions as well as small series or even single pieces, with power, voltage and size according to the customer's requirements.
