History and technological development
ELKA, an electrical engineering company and cable factory, was founded in 1927 in Zagreb. Since then, the company has continuously expanded its product range and technological capacities, becoming the leading cable manufacturer in the region.
Latest investments and projects
2022-2024
Intensive investments in new machines and technologies, including machines for copper processing, making cable sheaths and shielding of insulated wires. Projects for the construction of a new finished goods warehouse (2024) and the installation of a solar power plant on the renovated roofs of the production halls (2024) have also been launched.
