500KV PHU LAM - O MON: 12 DAYS Ahead of Progress

The 500kV Phu Lam - O Mon transmission line has a total length of 34.334km including 83 pillars, leading from the 500kV Phu Lam substation to the end of the second circuit of the 500kV Nha Be - O Mon transmission line. In which, Song Da 11 Joint Stock Company undertakes the construction of lot 6 from the first point to the G5 point with a length of nearly 15km with 37 foundation positions, passing through Binh Tan and Binh Chanh districts of Ho Chi Minh City. Ho Chi Minh City and Ben Luc district of Long An province.

The 500kV Phu Lam - O Mon transmission line project is one of the key works in the national power system development planning. At the request of the Investor, the construction of a mixed line section with 01 500kV circuit and 02 220kV circuits with 1-circuit tension (reconnecting for the 220kV Phu Lam (273) - Long An 1 (273) line coincident with the center line. from position 23 to position 37) must be taken in 140 days (February 10, 2012 to June 30, 2012).

To complete a large amount of work including: digging, casting 37 foundation columns, erecting more than 728 tons of steel columns; pulling more than 71km of ACSR666.6 MCM conductor, 18km of ACSR795 MCM conductor, nearly 12km of 7/6AWG lightning conductor and OPGW 90 optical cable combination lightning protection line; At the same time, 120.9 tons of steel poles, 17.5km of ACSR795 MCM conductors and more than 6.5km of lightning protection wires of 220kV Phu Lam (273) - Long An 1 (273) transmission line must be recovered for a period of time. It's really not that simple.

In addition, inherent difficulties from compensation, site clearance, securing materials and capital, unfavorable weather; waiting for the construction permit to pull the rope through 02 positions at poles 33 and 34, 99.5m high, crossing the city highway. Ho Chi Minh - Trung Luong; or asking permission to cut off power to medium voltage lines that have cross-sections with lines to make scaffolding to support wires, etc., makes the construction work more difficult.

Therefore, right after the power was cut off on the existing 220kV Phu Lam (273) - Long An 1 (273) line, Song Da 11 Joint Stock Company and Song Da 11 Investment and Construction Joint Stock Company launched a war. emulating 140 days and nights on the construction site, and at the same time focusing all means, motorbikes and labor force to speed up the construction progress, ensuring the completion of the schedule as committed to the Investor with high quality. maximum workload and maximum safety.

Overcoming all difficulties and hardships, with the determination and enthusiastic working spirit of the collective staff, engineers and workers of Song Da 11 Joint Stock Company and Song Da 11 Investment and Construction Joint Stock Company , the construction of 500kV Phu Lam - O Mon transmission line from positions 23 to 37 (the section coincides with the center of the line) has been completed, re-establishing and paying electricity for 220kV Phu Lam (273) - Long An 1 line (273) at 21:05' on June 18, 2012, finishing 12 days ahead of schedule.

The victory of the employees of Song Da 11 Joint Stock Company and Song Da 11 Investment and Construction Joint Stock Company in the 140-day and night emulation campaign on the 500kV Phu Lam - O Mon transmission line is a practical action. welcome the 8th Trade Union Congress at all levels, towards the 8th Song Da Complex Trade Union Congress - term 2012 - 2017.

In that excited and excited atmosphere, all employees of Song Da 11 Joint Stock Company and Song Da 11 Investment and Construction Joint Stock Company built on the 500kV Phu Lam - O Mon transmission line project. complete the remaining items to put the project into operation before December of this year. In order to once again affirm the position of the Company in the field of construction and installation of large-scale power transmission lines, difficult and complicated construction conditions, requiring urgent progress; at the same time, contributing efforts to the industrialization and modernization of the country.
