Wind turbines stand tall on the landscape both onshore and offshore, harnessing natural resources to generate renewable energy. The cables used in these installations must be specifically engineered to handle unique mechanical and environmental challenges. Unlike standard industrial cables, wind turbine cables must withstand continuous torsional stress caused by the rotation of the nacelle and rotor blades, which can apply twisting forces up to ±180° per meter over millions of cycles during the turbine's 20-25 year operational lifespan. Our comprehensive range includes power cables rated from 600V to 6kV for tower, nacelle, and rotor applications, as well as control and automation cables essential for safe operation and real-time monitoring of energy production systems.

UNE 21123 standard refers to the design and cross-sectional area specifications for cables used by utilities on power distribution circuits with voltage ratings up to and including 600/1000V (0.6/1kV). UNE standards are released by AENOR (Asociación Española de Normalización y Certificación), the Spanish Association for Standardisation and Certification. As AENOR is a member of ISO, IEC, and CENELEC, many of its standards are harmonized with European and international conventions.

HD 620 is commonly linked to the German national standard DIN VDE 0276 Part 620 and is harmonized with international standard IEC 60502-2. The standard establishes comprehensive construction requirements, dimensional specifications, and test methods that exceed the baseline requirements of IEC 60502-2. Both HD 620 and IEC 60502-2 require compulsory conductor and insulation screening, typically applied through a triple extrusion process with the insulation layer. The test methodology for compliance is set out in HD 605 subclause 2.1.1 for insulation material and HD 605 subclause 2.1.2 for sheath material.
