RADOX® cable technology

RADOX® cable technology

RADOX® stands for "radiation X-linked" and describes the process of crosslinking thermoplastic polymers by means of electron beams. HUBER+SUHNER has been using this technology, which was developed in-house, successfully since the 1970s to achieve notable improvements in the thermal, mechanical and chemical properties of the cable insulation material. RADOX® cables do not melt, possess better abrasion resistance and greater cut resistance than conventional cables and, even with thinner insulation, are much more resistant to various environmental factors.

Overview of advantages

  • RADOX® does not melt
  • No drip-off from insulation material in case of short circuit
  • Extended lifetime at lower temperature
  • Less shrinking of insulation material in higher temperature
  • Better heat ageing performance
  • Better fire performance

  • Thinner insulation due to improved mechanical and chemical resistance properties
  • RADOX® withstands temperature peaks
  • Improved abrasion resistance
  • Improved cut through resistance

  • Better environmental resistance (UV, ozone, weathering, water, salt water etc.)
  • Better resistance against liquids (oil, battery acid, grease, AdBlue, solvent resistance and other chemicals)
HUBER+SUHNER develops the RADOX® materials itself. The cables are designed and manufactured in accordance with international standards, as well as customer-specific requirements. Decades of experience, continuous quality checks and extensive laboratory tests guarantee the highest quality standards.

To meet rising demand, a new mixing plant was built at the Pfäffikon site in 2011 for the preparation of the mixtures. This highly automated production facility manufactures all the RADOX® variants for the different areas of application. In the extruder, the mixture is ultimately applied to the conductor material by means of melt extrusion.
Electro-beam crosslinking
Electro-beam crosslinking
The RADOX® cables are completed by electron-beam crosslinking. The cable is passed through the crosslinking system in a controlled manner. Radiation with high-energy electrons changes the chemical structure of the polymer across the entire circumference of the cable. The molecules of the polymer are then cross-linked, which brings the process to a close.
