Dai Long electric cable was chosen as the material to supply the 500kV circuit 3 line project in Ha Tinh

TPO - During the harsh days of June in the Central region, groups of workers still braved the hot sun to stay at the construction site of the 500kV circuit 3 line through Ha Tinh to carry out the process of pulling cables hundreds of meters high on high voltage electric poles.

In June, along the 500kV 3-section line through Ha Tinh province, thousands of officials, engineers, and power industry workers tried to spread and pull wires onto towering electric poles. Despite the hot weather, each group of workers still worked and completed the line on schedule.At poles 135 and 136 across Cam Xuyen district (Ha Tinh), groups of workers from PC1 Hanoi Joint Stock Company are pulling the first electric cables onto the 145m high pole. Because the route crosses Thuong Tuy Lake, the distance between these two columns is more than 1km long. To ensure a safe distance, the two columns are designed higher and become support columns.Photo: TIENPHONGThe large pillars are 145m high, weigh 426 tons, and use tube column technology, used for the first time in an ultra-high voltage line project in Vietnam. The contractor took a lot of time to erect these columns.Photo: TIENPHONGAfter the pole erection phase, contractors are now pulling the cables. Materials and equipment are brought to the base of the column. Each coil has a length of 2,000-2,400m and weighs 5-6 tons.Photo: TIENPHONG Laying the rope and hanging the rope is considered a difficult step. This job requires workers to be both healthy and have combat experience because they must constantly cross mountainous terrain, rivers and lakes. In addition to human strength, groups of workers also have to use plows and winches.Photo: TIENPHONGMr. Dinh Huu Van (born 1983, from Nghe An) said that due to the hot weather, the group of workers had to get up early to go to work. The route through Ha Tinh has mountainous terrain, crossing rivers and lakes is quite dangerous, so the construction process encountered many difficulties.Photo: TIENPHONGOn the line there will be 26 wires (24 conductors, 1 fiber optic cable and the remaining 1 wire used for lightning protection).
