What Elka does

ELKA d.o.o. is a Croatian electrical cable manufacturer founded in 1927 and headquartered in Zagreb, operating as a wholly-owned subsidiary of Iskra Group since July 2021. The company produces medium-voltage (up to 36 kV) and high-voltage (up to 132 kV) power cables using XLPE insulation with advanced triple extrusion technology and dry crosslinking in neutral nitrogen gas. ELKA also manufactures low-voltage power cables, telecommunications and signal cables, marine and submarine cables, railway cables, self-regulating heating cables, and specialized halogen-free fire-resistant installation cables for buildings. In December 2025, ELKA became the first cable manufacturer worldwide to receive VDE certification for 110 kV cables — the highest voltage level VDE currently certifies.

The company serves B2B customers across four primary verticals: energy (utilities, grid operators, and renewable energy projects — its primary segment), marine and offshore (shipbuilding and offshore platforms), railway and transport (vehicle manufacturers and operators), and construction and telecommunications. Named enterprise customers include Siemens, Airbus, HEP (Croatian power utility), HZ (Croatian Railways), Faber, and, as of 2026, Saudi Energy. ELKA holds ISO 9001, 14001, 45001, and 50001 certifications and was named Croatia's most successful large company in the 2024 Zlatna kuna award.

ELKA operates a direct enterprise sales model with a 252-person workforce and 25,000 tons of annual production capacity. The company has invested over 25 million EUR in modernization and new production lines over the past three years, with two additional Rosendahl lines scheduled for 2026 delivery. Go-to-market relies on dedicated sales contacts and active participation in major international trade fairs (Hannover Messe, Wire & Tube Düsseldorf, Middle East Energy Dubai, Saudi Elenex), sometimes alongside Iskra Group. The company is currently expanding internationally, with Saudi Energy supplier approval in 2026 marking its first explicit Middle East market entry.

Broad incumbents

• LS Cable & System: Korean global cable manufacturer with leading positions in HV power cables, submarine cables, and specialty cables, including a growing European presence. Direct product overlap with ELKA, but with substantially larger scale and global reach.
• Nexans: French global cable manufacturer with strong positions in HV power transmission, submarine cables, and specialty industrial cables. Closely comparable product range to ELKA, particularly in HV power and marine/submarine cables, but with multi-billion-euro revenue and integrated EPC capabilities.
• Leoni AG: German cable and wiring systems manufacturer with a wire and cable division producing power, specialty, and industrial cables for energy, automotive, and infrastructure. Comparable in product mix to ELKA's specialty cable lines, with broader geographic reach and a focus on wiring systems.
• NKT A/S: Danish cable manufacturer with a leading position in HV power cables and submarine cable systems, including recent VDE-certified HV products. Highly comparable to ELKA in the HV power cable segment, though NKT is significantly larger and more focused on turnkey submarine cable projects.
• Prysmian Group: Global #1 cable manufacturer offering power cables, submarine cables, telecom cables, and specialty cables for utilities, energy, and infrastructure. Directly comparable product portfolio to ELKA across LV/MV/HV power, marine, and telecom cables, but operates at vastly greater scale (€15B+ revenue) and with global multi-site manufacturing.

Regional players

• Reka Cables: Finnish cable manufacturer producing power, installation, and telecom cables for buildings, industry, and energy. Comparable in scale and product mix to ELKA, but primarily serving Nordic and Northern European markets rather than ELKA's CEE/Middle East focus.

Direct peers

• Tele-Fonika Kable (TF Kable): Polish cable manufacturer producing power cables, telecom cables, and specialty cables, headquartered in CEE with international reach. Closest size and product-portfolio match to ELKA in Europe, including HV power cables, marine cables, and railway cables for similar European and Middle East customers.
• Brugg Cables: Swiss cable manufacturer focused on HV and EHV power cables, including special-purpose and submarine cable systems. Direct peer to ELKA in the high-voltage power cable segment with comparable size, strong European positioning, and emphasis on specialty cable certifications.
• Hellenic Cables: Greek cable manufacturer (part of Viohalco) producing HV and EHV submarine and underground power cables, plus telecom and specialty cables. Direct peer to ELKA in HV power cables and marine/submarine cables, with comparable scale and strong Mediterranean/European customer base.
• Tratos Group: Italian cable manufacturer specializing in power, marine, fire-resistant, and railway cables, including halogen-free and LSZH product lines. Closely comparable to ELKA in the specialty/marine/railway cable niches with similar size and European customer footprint.
