Шаблон:Multiple issues Шаблон:Infobox power transmission line The Dasmariñas – Las Piñas Transmission Line (abbreviated as 8LI1DAS-LPI, 8LI2DAS-LPI and DLPTL) 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).
History
The Dasmariñas – Las Piñas Transmission Line finished construction in July 15, 1999 but the power line only went into service when the Las Piñas substation was commissioned on November 30, 2001.[1]
Throughout its existence, several steel poles were painted with aluminum paint to protect them from corrosion.
Route description
The Dasmariñas – Las Piñas Transmission 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).[2]
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.
Ownership, operations, and maintenance information
The transmission line was originally operated, maintained, and owned by the government-owned National Power Corporation (NAPOCOR/NPC) from November 30, 2001 to March 1, 2003. Operations, maintenance, and ownership of the line then transferred to another government corporation National Transmission Corporation (TransCo) on March 1, 2003 where it operated and maintained the line until January 15, 2009. The line's operations and maintenance was transferred to privately-owned National Grid Corporation of the Philippines (NGCP) on January 15, 2009 where it now operates and maintains the power line since then.
As a result of the turnover from TransCo to NGCP, and Republic Act (RA) 9511 and concession agreement between both parties which authorized the latter to exercise the right of eminent domain necessary for the construction, expansion, and efficient maintenance and operation of the transmission system and grid and the efficient operation and maintenance of the subtransmission systems which have not yet been disposed by TransCo where NGCP acts as the temporary owner of these assets and facilities and they will be transferred to TransCo once the 50-year NGCP concession period ends on December 1, 2058, lands where the transmission structures stand and their pedestals or foundations and right-of-way or portions of a power line acquired and designated, and facilities built or placed whether using secondhand (NAPOCOR/NPC and TransCo-era) with a new function or entirely new structures from January 15, 2009 (steel pole 208A) are operated, maintained, and owned by NGCP, while those that were placed or built, acquired, and designated from November 30, 2001 to January 14, 2009 are owned by TransCo and operated and maintained by NGCP, as one mandate of the former is to handle all existing cases, including right-of-way and claims which accrued prior to the transfer of power grid operations and maintenance to the latter on January 15, 2009. Table showing the ownership information on each lands where the structures and their respective foundations and pedestals stand, and right of way is on the technical description section.
Technical description
| Structure type | Height | Weight | Insulators |
|---|---|---|---|
| Suspension steel pole (flag) | 74-86m tall | 7+ tons | 6 braced line posts (line 1 on upper 3 and line 2 on lower 3) made of 15 porcelain discs with steel crossarm at top segment (except pole 208 where it has only 3 insulators (line 1) and the lower 3 was removed due to the construction of a lattice tower (line 2) that is located on a former location of a water tower in 2016). |
| Anchor steel pole (flag and irregular) | 6 horizontal dead-end insulators (line 1 on upper 3 and line 2 on lower 3) made of 15 porcelain discs with 6 horizontal pole-mounted porcelain insulator at the center. Irregular variant of the anchor steel pole exists where it is only used on pole 209. | ||
| Lattice tower | 55m | no calculation | 6 horizontal dead-end insulators made of 23 discs and 4 connecting to Las Piñas substation. Used only on National Grid Corporation of the Philippines (NGCP)-owned, operated, and maintained lattice tower 208A. |
| Bundle type | Spacers | Amps | Broken spacers |
|---|---|---|---|
| quadruple bundle | 500 + | not measured | 0 |
| Owner | Number of lands and structures owned | Percentage (by number of lands and structures) |
|---|---|---|
| National Transmission Corporation | 209 (steel poles) | 99.52% |
| National Grid Corporation of the Philippines (owned, operated, and maintained) | 1 (lattice tower) | 0.48% |
