DUO cable clamp

DUO
2-conductorcable clamp type Duo 44-61 / 27-29

In demanding railway infrastructure projects, you need robust cable clamps that not only guide and protect the main cable, but also the return or earth conductor. Our DUO cable clamp offers you exactly this solution: space-saving, reliable, and compliant with the relevant standards. Developed for low, medium, and high-voltage cables, it meets the highest requirements for safety, durability, and ease of installation, even under harsh environmental conditions in the railway infrastructure sector.

Key features and benefits

• Design and purpose

  • Double clamp, holding two cables or cable pairs at the same time; particularly suitable for securely guiding a return or earth conductor in addition to the main cable.

• Advantages in the railway sector

  • Space-saving and safe: compact bundling reduces installation effort and prevents loose conductors.
  • Greater operational safety: integrated guide for return or earth conductors increases reliability in traction power systems.
  • Quick installation: pre-assembled parts or quick fasteners facilitate installation even in tight railway enclosures.
  • Versatile: suitable for low, medium, and high voltage

• Materials, temperature & certifications

  • Glass fiber reinforced PA66 or equivalent heat-resistant materials.
  • Certifications according to relevant standards (e.g., EN/IEC 61914, RoHS/REACH) depending on model.
  • Resistance to oil, grease, frost, heat, UV, ozone, salts, moisture, acids, and aggressive chemicals. 
  • No oxidation, corrosion, magnetism, or conductivity. 
  • Halogen-free and no sharp edges.

• Application examples in the railway sector

  • Installation of main and ground cables on masts or posts in track systems.
  • Bundling of conductor packages in traction power systems, switchboards, and substation areas.
  • Safe routing of return conductor/ground conductor connections next to the main cable to meet grounding requirements.

Special features

By using the insert, in addition to a cable with a diameter between 44 and 61 mm, a second cable with a diameter of 18, 22, or 29 mm can also be laid on it.
