TPO – Of the 285 electric poles across Ha Tinh, many locations have gradually completed the cable pulling. Meanwhile, some other electric poles in difficult and rugged terrain are being erected by contractors, completing them soon as planned.

In early July, although the 500kV line 3 Quang Trach - Pho Noi project could not be energized on June 30 as the target set by the Prime Minister, thousands of officials, engineers and workers in the electricity industry along the line were working hard to complete the project soon. |
 |
The 500 kV line project, circuit 3, through Ha Tinh is over 141 km long with 285 pole foundation locations, 284 pole spaces/113 anchor spaces in 9 districts and towns. This is the locality assessed to have the largest workload and the most difficult terrain among the provinces where the line passes. After many months of construction, up to now, many locations on the line are gradually being completed. |
 |
According to the design, each electric pole will have 26 wires (24 electric cables, 1 optical cable, 1 lightning protection wire). |
 |
Despite the heat, groups of workers still stayed to work, completing the line early. In the picture is the pole position across Hoa Lac commune (Duc Tho district, Ha Tinh), workers are completing the final stage of pulling the wire. |
 |
Meanwhile, some locations with rugged terrain, high mountains, rivers and lakes are urgently completing the pole erection due to difficulties in transporting materials and equipment. |

The position of column 175 across Boc Nguyen lake (Cam Thach commune, Cam Xuyen district) is gradually being completed to move to the wire pulling stage. |
 |
According to engineers from Song Da Construction and Service Joint Stock Company, this is one of the three tallest support columns on the line, measuring 145m in height and weighing 426 tons. It uses pipe column coupling technology, the first time it has been used in a super high voltage power line project in Vietnam. The contractor spent a lot of time erecting these columns. |
 |
At the pillars over houses and irrigation canals of Ke Go lake through Cam My commune (Cam Xuyen district), the contractor had to set up scaffolding as a support to pull the wire. |
 |
Mr. Luong Thanh Trung (PC01 Joint Stock Company, Hanoi) said that each coil of power line wire is 2,000-2,400m long and weighs 5-6 tons. To spread and hang the wire, in addition to human power, plows and line winches are also needed. |
 |
“The wire laying process requires crossing forests, mountains, lakes, and canals, so it is very difficult. In difficult locations, we have to use supports, lift the wire, and pull the cable along the lead wire to avoid crossing the wire,” said Mr. Trung. In the photo, workers carefully tie each scaffolding to ensure safety when pulling the wire. |

Groups of workers worked through lunch to ensure the goal of pulling the electricity early. |

The representative of the Central Power Project Management Board (CPMB - investor of the 500 kV line project, circuit 3, Quang Trach - Quynh Luu) said that up to now, 160 poles have been erected, 125 poles are being erected; 15/113 anchorages have been wired. Currently, contractors are speeding up the progress to soon complete the line locations. |
