ACCC Conductor Installation Completed in Vietnam

286 km of ACCC Installed to Increase the Capacity of a 220 kV Transmission Line

To increase the capacity of a 220 kV transmission line running from the Bac Ninh province through the Hung Yen province to the Hai Duong province, the National Power Transmission Corporation #1 of Vietnam installed 286 km of 421.4 mm^2 (832 kcmil) Brussels size ACCC conductor. The project was completed in two phases to allow celebration of the Lunar Tet Festival, Vietnam's most important and joyous holiday.

The reconductor project was located in the Red River Delta region of North Vietnam which is affected by a hot and humid tropical monsoon climate. The average temperature is about 23 degrees C (73 F) and the average rainfall is about 1,550 mm (61 inches) per year. ACCC was selected over other high-capacity conductor alternatives due to its decreased sag and reduced line loss performance attributes.

The line traversed residential and agricultural communities and at one location accommodated a 700 meter (2,300 foot) river crossing.
