The Dasmariñas–Las Piñas Transmission Line (abbreviated as 8LI1DAS-LPI and 8LI2DAS-LPI) is a 230,000 volt, double-circuit transmission line in Metro Manila and Calabarzon, Philippines that connects Dasmariñas and Las Piñas substations of National Grid Corporation of the Philippines (NGCP).

Route description

Steel poles 202–209 (with 202, 204, 205, and 208 are suspension towers and have flag design while 203, 206, 207, and 209 are anchor towers) along Manila-Cavite Expressway (CAVITEX) in Las Piñas, Metro Manila and Bacoor, Cavite.

The Dasmariñas–Las Piñas Transmission Line went into service on November 30, 2001.[1] Originally commissioned by the government-owned National Power Corporation (NAPOCOR), it is now operated and maintained by privately owned National Grid Corporation of the Philippines (NGCP). The power line passes through the cities of Dasmariñas, Imus, and Bacoor in Cavite, and Las Piñas in Metro Manila. It is located within the service area of NGCP's South Luzon Operations and Maintenance (SLOM) District 1 (South Western Tagalog).

The transmission line starts at Dasmariñas substation, turns left into Ramon Tirona Avenue, and run parallel with Aguinaldo Highway until Bacoor. Upon approaching Bacoor Junction, it will parallel with Aguinaldo Boulevard until Bacoor Exit of Manila-Cavite Expressway (CAVITEX). It then utilize the eastern side of CAVITEX until its terminus at Las Piñas substation.

Statistics

The transmission line consists of 209 steel poles (1–209) and 1 lattice tower (208A).

Expansion and improvements

In order to protect the steel poles from corrosion, several poles are being painted with aluminum paint.

In 2016, NGCP constructed lattice tower 208A that connects to 3rd 300 MVA transformer at Las Piñas Substation on a location where a water tower was once located.

Notes
