When to Use Cross-Linked Cables Instead of PVC

Irradiated Cable in Transit Applications

Extremely high temperatures, continuous flexing, and plenty of stress and abrasion -cables used in harsh environments, such as commuter railways and military applications, will endure some of the most severe conditions anywhere! Relying on regular PVC cabling, which cannot tolerate excessive heat, can be dangerous. There is an alternative: Cross-Linked Cables. Cross-linked cables have greater stability at high temperatures than PVC cables.

Scientific Content Alert: All plastic materials, including PVC, are made of complex molecular chains called polymers. In their natural form, these molecular chains are not chemically bonded to one another. This means that if heat is introduced to the substance, those chains will be weakened and allow flow.

Creating cross-linked bonds between these molecular chains substantially increases stability at higher temperatures. Other benefits of cross-linked cables include:

  • Excellent Flame Resistance
  • Improved Durability and Toughness
  • Higher Ampacities
  • Greater Chemical Resistance
  • Easier Installations (Small Diameters, Flexible Stranding)

Cross-linking can be accomplished either chemically or by radiation, the preferred method. The radiation process uses a strong, direct electron beam (see illustration) instead of potentially damaging pressure or high temperatures. The radiation method can even be done on small conductor sizes.

Benefits of Radiation versus Chemical Cross-Linking:

  • Greater Cable Flexibility
  • Wider Range of Economical Insulation Thicknesses
  • Better Electrical Properties - No Chemical Catalyst Residue
  • No Separator Tapes - Less Pressure
  • Free Stripping
  • No Color Change or Fade
  • No Water Used

When selecting cables for transit or other applications that endure harsh environments, the important benefits associated with irradiated cross-linked cables make them a great choice. For a quote on irradiated cross-linked cables, please speak with your sales representative.
