About HELU
HELU (formerly HELUKABEL) is a German manufacturer and supplier of electrical connection technology headquartered in Hemmingen, Baden-Württemberg. The company produces and distributes cables and wires for industry, infrastructure and building technology, including control and connection cables, motor, servo and encoder cables, Industrial Ethernet and bus cables, fibre optic cables as well as spiral and drag chain cables. In addition to standard products, customer-specific cable solutions and special designs are developed. The portfolio also includes cable assemblies including motor-, servo- and encoder-side connectors, energy supply chains and energy chain systems (HELUCHAIN), LED industrial luminaires (SANGEL Systemtechnik), cable processing machines (KABELMAT) and AI-based 360° inspection systems for the quality control of extruded products (nLine). The conductors are made, among other things, of bare and tinned copper or aluminium with insulation and jacket materials of PVC, PP or PUR. The product range is qualified with international approvals such as VDE, HAR, UL/CSA, CCC, IEC, UKCA and EAC for worldwide use. According to the website's JSON-LD, the company employs 2500 staff.

Materials & Processes
Copper
Bare and tinned conductor, fine-stranded according to DIN VDE 0295 Kl. 5 or extra-fine-stranded according to Kl. 6 / IEC 60228, for power, control and data cables.
Aluminium
Conductor material in power distribution cables (e.g. NAYY) and as aluminium foil for shields.
PVC
Insulation and jacket material for static and occasionally flexible applications, partly flame-retardant optimised.
PP
Halogen-free core insulation for hybrid and servo cables.
PUR
Robust jacket material for drag chain, robot and Ethernet cables under mechanical and chemical stress.
Glass fibre (optical fibre)
Immune-to-interference data transmission over long distances in industrial and infrastructure cables.
Plastic optical fibre (POF)
Optical fibres for industrial data networks and moving applications.
HCS fibre (Hard Clad Silica)
Fibre type for fibre-optic industrial cables with medium transmission distances.
Steel
Material for energy supply chains and stainless steel mesh for rodent protection.
Stainless steel
Stainless steel mesh (80–85 %) as chemical-free rodent protection for photovoltaic cables.
