Founded in 1994 by U Chit Ko Ko, Sun Electrical Engineering & Construction Co., Ltd has grown through the dedication of its people and years of practical engineering work across Myanmar. Behind every project are people who depend on electricity to work, learn, receive care, and build their futures. That human purpose gives meaning to the infrastructure we help deliver.
Our project history spans substations, transmission and distribution lines, transformer installations, and electrical works for factories, housing developments, commercial properties, and public facilities. Each project adds to the experience shared across our team, connecting the knowledge of senior engineers with the development of the next generation.
As we move forward, we carry that experience with a sense of responsibility to our clients, our colleagues, and the communities our work serves.
