Sumitomo Electric Industries, Ltd. has been awarded a contract for for high-voltage underground cables (115kV cross-linked polyethylene insulated vinyl sheath triplex (CVT) cables) from Electricité du Cambodge (EDC), as part of the Phnom Penh City Transmission and Distribution System Expansion Project.

The capital, Phnom Penh, is the center of the Cambodian economy and society, accounting for almost 70% of total electricity demand in the country. However, due to the limited capacity of power transmission, transformation, and distribution facilities and an undeveloped power grid control system, the city can still suffer from power outages over large areas and for long periods.

Against this backdrop, the Phnom Penh City Transmission and Distribution System Expansion Project was initiated to stabilize power supply in the city. Sumitomo Electric, in cooperation with its partners, Toenec, Siemens Ltd. Thailand will create and expand substations, lay transmission and distribution lines, and install power grid control systems. This project is financed by Japanese ODA loans totaling 6.48 billion yen.

For this project, Sumitomo Electric is supplying high-voltage underground cables (115kV CVT cables) connecting substations (total distance: 15 km; total cable length: 20 km). The CVT cable consisting of three stranded single-core cross-linked polyethylene insulated vinyl sheath (CV) cables can reduce the workload and spaces required for installation compared with single-core CV cable. The stranded cable can also mitigate thermal behavior inherent to power cable and eliminate part of installation process. The number of manufacturers that can produce the 115kV CVT cables
is limited. Long recognized for its stable supply record,
Sumitomo Electric has been awarded.

Through the execution of this project, Sumitomo Electric will enhance the stability of the capital's power supply and contribute to the economic development of the Kingdom of Cambodia.
