Business Introduction

We, EMT Co., Ltd. are at our best from a true specialist’s aspect with advanced technology and accumulated experience of 35-years…

In the year of 1965, we first founded the firm, namely Shin-A enterprise, starting to manufacture electrical equipment for di t ib ti t d th i t f t h l gi l f d ti H d h d d i distribution system under the poor circumstance of a technological foundation. However, nowadays, we have succeeded in becoming one of the most prominent firms in the nation. Our responsibility is to develop, innovate and supply improved “heavy electrical equipments: in order to bring and boost the productivity and quality through supplying the choicest produce free frompower failure and accidents. Taking on such an important role, we are making our best efforts with untiring research and development work along with a perfect quality control system.

As a result of that, our products; Non-Grounding High Voltage Distribution equipments, 25.8KV Disconnecting Switches, lightning Arresters, 25.8KV Auto Section Switches, 25.8KV Interrupter Switches, 25.8KV Automatic Line-Sectionalizers and 25.8KV SF6 Gas Load Break Switches have become the most competitive among other similar products. We will do our best for both manufacturingand enhancing service for our customers and faithfully playing a role as a specialized firm, both in name and reality.and enhancing service for our customers and faithfully playing a role as a specialized firm, both in name and reality.

Research and Development

We believe in saying “harvested as good and much as seeded” Continuous research will bring the promise of tomorrow.

It took substantial years before the trade mark “EMT” become trusted by customers. However, much more untiring day-to-day effort is needed in order to gain and enjoy the trust by customers for the betterment in the field of electrical equipment industry.Therefore, we aggressively invest in the research of Hi-tech and advanced technologies.The way to continue innovation in the plant facilities, while making contracts in technological introduction with leading specialized manufacturers abroad, staying one step ahead of our competitors, is a part of our policy. In addition, through the

t d ti d t f R h d separated operation and management of Research and Development Div., we will do our best to try to bring up and develop new equipments and systems.
