SETI, founded in 1994, continues to grow and develop steadily in the high efficiency distribution transformer field, and stands out in the public power sector and the civil sector. Based on the ISO 9001;2015 certification, the quality policy of "customer satisfaction through overall improvement" has been continuously promoted, and the new plant before completion in 2019 has a work site and It is composed of several auxiliary facilities including office buildings, making every effort to improve technology and support customers. One of the many reasons why customers prefer our high-efficiency distribution transformers is that we produce transformers that thoroughly comply with the regulations of KEPCO, In addition, the following factors motivate us to trust our products more. - Apply the best technology and manufacturing method based on more than 25 years of transformer manufacturing experience - Careful observation of the entire process in the manufacture of high-quality transformers and the application of a thorough ISO 9001 quality assurance system - Compliance with ISO 14001 Environmental Management System to promote environmental protection and appropriate use of natural resources during the production process of transformers - Securing reliability and establishing a systematic verification system with the materials and parts suppliers that make up the transformer Customers have more technical knowledge than anyone else about components and incidental devices that can improve transformer quality. SETI's technicians and managers are always sharing projects with customers and giving advice. One of our design techniques focuses on the end cost and quality of our customers I'm matching it. SETI is equipped with sophisticated test equipment and is conducting tests that comply with IEC and ANSI standards.
