Budarhalslina 1. - 220 kV Overhead Transmission Line

Budarhalslina 1 is an overhead transmission line from the substation at Budarhals to Hrauneyjarfosslina 1 at Langalda in south Iceland. Mannvit played an important role during the preparation of the HV line and the Budarhals HEP, including research, preliminary design and feasibility study. Mannvit also performed the environmental impact assessment (EIA) and supervision of related EIA work. At construction phase Mannvit carried out the design, tendering and tender documents as well as various tasks during construction, such as procurement assistance and assisting Landsnet‘s workers on-site during stringing of conductors and earth wires.

 

Budarhalslina 1 is a 5,6 km long 220 kV transmission line from Budarhals Hydropower Station to Hrauneyjafosslina 1 where it is T-connected. The required capacity for the line is 100 MVA although a 432 MVA capacity can be reached at 40°C because conductors were chosen in relationto mechanical breaking load. The environmental impact assessment (EIA) of the line was carried out by Mannvit and was performed parallel to the EIA of the plant itself but the line route was changed in 2010, as stated in a press release by Landsnet (owner and operator of the line).
