EFLA's team of transmission line specialists, renowned for their expertise, is designing critical high-voltage power lines in southwest Sweden. The project is being led primarily by EFLA's team in Iceland, with support from staff in Sweden, ensuring a comprehensive and efficient approach.
Connected to EFLA's first project in Sweden
The project involves demolishing an ageing 400 kV high-voltage line supported by nearly 70-year-old steel towers. In its place, a new 400 kV high-voltage line will be constructed to meet modern standards, offering greater capacity and reliability. The new line will span approximately 70 kilometres and have about 190 new towers.
One of the project's most intriguing aspects is the formidable challenge of keeping at least one of two parallel lines in operation, a critical factor for the power supply in southwest Sweden. This complexity adds a layer of significance to the design, as one of the lines must remain operational throughout. Part of the project includes reusing existing double circuit towers that include lines from both parallel lines from a previous project in which EFLA was involved. This earlier project marked EFLA's first venture abroad, setting a solid foundation for the company's international work.
Initially, the plan was to build two independent high-voltage lines. However, the project owner, Svenska Kraftnät, later requested that the lines be partly combined in the existing towers to minimise the project footprint.
EFLA is responsible for the tender design and the redesign of the preliminary design based on the project owner's updated requirements. With EFLA's extensive experience in high-voltage transmission lines, the company remains a leading provider of expertise in northern Europe for projects of this scale.
