Estel Company Limited was established in 1987 to produce high-quality, small and medium capacity transformers and reactors in Thailand. Through technical collaboration with Wagner+Grimm AG, a leading Swiss manufacturer in this field since 1953, Estel is continually provided with state-of-the-art technology and know-how so we can best satisfy both local and international demands. We can supply products which comply with any international quality standards such as IEC, UL, CSA, VDE, SEV, BS, CE, ANSI as well as Thailand's Industrial Standard (TIS). Furthermore, we have attained the prestigious ISO 9001 certifications for our quality management system not only from the National Accreditation Council of Thailand (NAC) but also from the United Kingdom.

Estel's policy is based on maximum customer satisfaction. This means providing the idea solution, or the right, top quality product at the most competitive price on the date requested.

In addition to our standard product line of transformers and reactors, ESTEL specializes in developing customized products to fit specific applications. Using advanced computer design software obtained from Switzerland and with an in-house database that includes more than 20,000 designs, our engineers can quickly design a tailor-made solution to meet each customer's requirements.

As a member of the Federation of Thai Industries, ESTEL is not only working to satisfy growing local and international demand for transformers and reactors, but to upgrade the standards and reputation of Thai manufactured products to make the country a prime competitor in global markets.
