The company COMPAÑÍA REGIOMONTANA DE SERVICIOS, S. A. DE C.V. began operations in November 1987, to meet the growing demand of the electrical industry. In 1989 we started in the manufacture and repair of distribution transformers offering our services to the CFE and private industry. This same year we were awarded by the CFE-LAPEM the certificate of reliable supplier for the repair of distribution transformers. In July 1998, the growth of our company allowed us to acquire a new plant in the municipality of Santa Catarina N.L. of more than 6500 m2 achieving with this to develop our operations in a better and broader work environment. In this same year, our certificate before CFE-LAPEM was extended to transformers of up to 40 mva of power in 115 kv. Today our company is certified by the CFE-LAPEM for the repair of transformers of up to 120MVA of power and 400KV of tension with column and armored cores.
