What HELU does

HELU, legally HELUKABEL GmbH, is a German privately held manufacturer and supplier of electrical connection technology systems, headquartered in Hemmingen, Germany. Founded in 1978 and led today by Managing Director Marc Luksch as a family-owned business, the company designs, manufactures, and distributes a comprehensive portfolio of industrial cables (control, data, Ethernet, fibre optic, motor/servo, temperature-resistant, and continuous-motion cables), connectors (including the proprietary HELUTEC brand), cable glands in plastic, brass, and stainless steel, cable accessories and tools, and complete energy chain systems that combine flexible cable carriers with pre-assembled cables for dynamic industrial applications. The Aufmaster sub-brand provides cable measurement and quality assurance solutions, and E-business services (EDI, EPLAN, OCI) and an online configurator support digital procurement for industrial buyers.

HELU serves industrial OEMs, system integrators, and infrastructure customers across at least eight verticals: manufacturing and machinery (the primary segment), infrastructure and building technology, renewable energy (solar and wind), transportation (automotive, railway, marine, e-mobility), media and event technology, food and beverage, medical technology, and oil, gas, and chemical. With approximately 2,500 employees operating from 76 facilities in 43 countries, the company combines direct enterprise sales, an e-commerce storefront (shop.helu.com, shop.helukabel.com), and a contract partner network offering local warehouse inventory and scheduled deliveries. Pricing is quote-based and negotiated, with multi-year contracts for partners.

The business model is predominantly hardware sales across cables, connectors, glands, and accessories, supplemented by services for custom cable assembly, system integration, and digital procurement. Revenue is not publicly disclosed. In 2025 the company rebranded from HELUKABEL to HELU to signal a strategic shift from a cable supplier toward a complete electrical connection systems provider, and it continues to invest in regional capacity (notably an expanded Swiss facility in Bremgarten in 2026) and wholly-owned subsidiaries in Hungary, Switzerland, South Korea, and Brazil.

Direct peers

• Lapp Group: German family-owned manufacturer of industrial cables, connectors, and cable accessories. Lapp is the closest comparable to HELU by ownership structure (founder family), product portfolio (Ölflex control cables, ETHERLINE data cables, connectors, glands), go-to-market (direct + distributor), and target verticals (industrial machinery, automation).
• Leoni AG: German manufacturer of cables, wiring systems, and related services, historically focused on automotive and industrial customers. Highly comparable to HELU on product (specialty cables, wiring harnesses), end-markets (industrial machinery, automotive, transportation), and German manufacturing heritage.
• igus GmbH: German family-owned manufacturer of energy chain systems (cable carriers), chainflex continuous-flex cables, and readychain pre-assembled systems. Directly competes with HELU's HELU Energy Chain System and continuous-motion cable lines for robotics, automation, and machinery customers.
• TKD Kabel GmbH: German specialty cable manufacturer offering control, data, servo, and robotic cables plus cable assemblies. Direct competitor to HELU in industrial machinery and factory automation cable categories; similar mid-market, family-influenced profile.

Broad incumbents

• Nexans SA: French global cable manufacturer with energy, telecom, and industrial segments. Overlaps HELU on power, installation, and renewable energy cables; operates at much larger scale and is more exposed to utility-scale T&D projects.
• Belden Inc. US-listed specialty cable and connectivity solutions provider focused on industrial Ethernet, broadcast, and enterprise networking. Compares to HELU on industrial Ethernet/BUS cables, data cables, and the connector/accessories business (including the recently acquired Precision Optical Technologies).
• Phoenix Contact: German family-owned manufacturer of industrial connectivity, automation, and electronic interface products including connectors, terminal blocks, and cabling solutions. Compares to HELU on industrial connectors (competes with HELUTEC) and cable-to-connector system solutions.
• Prysmian Group: Largest global cable manufacturer with broad portfolio spanning energy, telecom, and industrial cables. Overlaps HELU on energy/power cables and industrial verticals but operates at vastly larger scale and is more diversified into T&D infrastructure than HELU.

Regional players

• Reka Cables: Nordic-based cable manufacturer focused on low-voltage power, installation, and specialty industrial cables. Comparable to HELU on product categories (installation cables, energy/power cables, fire alarm) but operates primarily in Northern Europe rather than across HELU's 43-country footprint.
