The Story Behind Every Perfect Cable

To guarantee stability, performance and safety, every HELU product undergoes rigorous testing at our R&D centre in Windsbach, near Nuremberg — where cables are bent, pulled, ground and ignited to find their true limits.

Tests are performed in accordance with national and international standards, so quality is always confirmed and guaranteed. HELU's control, signal cables and accessories hold VDE (Germany) certification along with numerous international approvals such as UL, CSA, SGS, BSI, TÜV and more.

Our testing facilities:

Torsion test tower for wind power cables
Drag chain test equipment
Fire testing equipment
Abrasion testing equipment
Test facilities for bending and torsion requirements
Aging furnaces compliant with UL, VDE, CSA, HAR, TÜV, and CCC standards.

Your advantages at a glance

Proven durability

All cables and wires used in moving applications are tested for bending, torsion, abrasion, and kinking beyond real-world load levels, giving customers confidence in reliability throughout the product's service life.

State-of-the-art testing facility

At the Windsbach testing center in Germany, products are simulated using high-tech equipment — from an 8-meter torsion tower for wind power cables to drag chain test systems reaching speeds of up to 10 m/s.

Reduced downtime risk

Products withstand millions of continuous bending/torsion cycles, helping customers minimize failures, fire hazards, unplanned downtime, and maintenance costs in real-world operation.

Put to the Ultimate Test

7 demanding tests that simulate real-world operating conditions, ensuring every HELU product performs reliably over its full lifetime.

Internationally Approved Cables and Wires

Whether in mechanical engineering, automation, or building technology, cables must function safely and reliably. Standards and certifications ensure that defined quality and safety standards are upheld. Testing procedures confirm that cables fulfil the required material properties and electric parameters. This makes these cables suited for approved installations and optimally prepared for export worldwide.

We offer cables and wires with a number of approvals: VDE, HAR, UL/CSA, CCC, IEC, and UKCA. With these, they fulfil both domestic and international requirements, including those of European industry, North American systems, and projects in Asia.
