Sumitomo Electric Wins Major Orders for Low-Loss HighCapacity Overhead Conductors from Asia-Pacific Region- Yen-loan projects in Bangladesh, Sri Lanka, Papua New
Guinea and India In December 2019, Sumitomo Electric Industries, Ltd. began shipping low-loss
high-capacity overhead conductors for the Dhaka-Chittagong Main Power GridStrengthening Project in Bangladesh. The Company is accelerating its powertransmission line business in the Asia-Pacific region, with major orders for a totalof 9,300 km of low-loss high-capacity overhead conductors, not only in
Bangladesh, but also in India (October 2019), Sri Lanka (September 2019), andPapua New Guinea (April 2019) under ODA loan projects.
Amid the developing economies and expanding energy consumption in the Asia-Pacificregion, there is a growing need for products that enable efficient energy supply inpower transmission. Transmission loss tends to be large particularly for long-haultransmissions, and therefore, our low-loss high-capacity overhead conductors areexpected to meet the need.
Ourconductor uses a steel core material that is 1.3-times stronger than conventional

materials, successfully reducing the core diameter, while increasing the aluminum ratioby tightly placing trapezoidal aluminum wires without gaps around the core. As a result,while maintaining the outer diameter and tensile strength, this conductor reduces
electrical resistance and thus transmission loss by 20-25% compared to conventional
conductors.
The features of this low-loss high-capacity overhead conductor are being recognized
and increasingly adopted by Asian countries including Bangladesh and Sri Lanka,
where energy demand is rapidly increasing.

Awarded orders for our new conductor in Asia- Pacific region[Bangladesh]
In March 2019, Sumitomo Electric received orders for low-loss high-capacity overhead
conductors for the projects of Power Grid Company of Bangladesh Ltd. from KEC
International Ltd. in India through Mitsubishi Corporation. These projects construct newoverhead power transmission lines under the Dhaka-Chittagong Main Power Grid
Strengthening Project and the Matarbari Ultra Super Critical Coal-Fired Power Project.
Sumitomo Electric began shipping in December 2019.
At the project sites in Bangladesh, high wind speed was assumed and thus required astrong pylon design. Adoption of our low-loss high-capacity overhead conductors,
however, enabled a smaller diameter while maintaining similar transmission capacity as
conventional conductors, reduced wind pressure on the conductors, and mitigated theload on the pylons. Consequently, the required strength of the pylons was reduced,contributing to the reduction of overall construction costs.

Sumitomo Electric continues to leverage its experience in the power transmission line
business accumulated in and outside of Japan and supply high-quality products, inorder to contribute to a stable power supply in the Asia-Pacific region and around theworld, and thus contributes to the development of each country.
