Gullarängen / Nynäshamn 130 kV, Stockholm

Linxon is providing two turnkey substations to Vattenfall Eldistribution, which will replace old equipment in Gullarängen and Nynäshamn. This modernization is part of Vattenfall’s large-scale “Capacity Stockholm” program, a major investment with the aim of strengthening the electricity grid and upgrading the regional network around the capital of Sweden.

Linxon’s commitments for these two new orders include project management, design, construction and civil engineering, delivery and installation of equipment and, finally, commissioning of the facility.

As part of this, the existing 70 kilovolt (kV) air-insulated outdoor switchgear will be replaced by gas-insulated indoor switchgear and, at the same time, the voltage will be raised to 130 kV. In Gullarängen, the medium-voltage switchgear as well as a power transformer will also be replaced.

Furthermore, Linxon will construct two modern buildings for the substations. An upgrade like this increases both the operational and delivery reliability of the facilities.
