Description

Description

Standards

  • Product
    IEC 60502-1
  • National
    NEK 536

Power distribution cable, designated for road lights, entry point installation or other general outdoor use (UV-resistant).

The cable is fire-retardant and halogen free, each phase having insulation and an outer sheath.

Can be placed directly in soil.

When laying at a lower temperatures than 0 degrees Celsius, care must be taken to avoid damage to the outer sheath. It is especially important that the cable is not exposed to impact at temperatures below 0  °C.

When laying at lower temperatures than -10 degrees Celsius, the cable should be preheated before laying as well.

If the cable is cut and not installed immediately, each phase must be sealed, to prevent water intrusion.
