Cable ladder 67 in Logo

Description

Use

  • For support and distribution of large-calibre power and communication cables.
  • Cable ladder system for indoor and outdoor applications. Suitable for humid, saline and chemical environments. Good behaviour against the UVs and outdoor exposure. Made in U23X and U48X, materials boasting wide experience in outdoor use.(1, 2)

Advantages

  • Insulating Cable ladder system with no earthing required.
  • Unex Cable ladder is entirely manufactured in insulating material (U23X and U48X). The whole mass is resistant to corrosion. Suitable for humid, saline and chemical environments.(2)
  • Provides better cable ventilation and less dirt holding due to its open base.
  • Allows 2 and 3 m distance between supports, at full load, due to its robustness.
  • Good performance with exposure to the UVs and to the elements.
  • The cable ladder is insulating and does not require earthing.

Easy-to-install

  • The Cable ladder profiles are supplied completely factory assembled and ready-to-install. They are 3m long and have rungs every 300 mm.
  • Perforated rungs and side rails.
  • Fast junction system with thermal expansion absorption.
  • Rungs compatible with standard 21x41 rail nut for fixing cable clamps or other elements.
  • Full set of series production fittings making a ready-to-mount KIT. Available in standard bend radii of 300 mm and 600 mm.
  • Provided with a wide range of cable cleats in U48X compatible with rungs for a durability equivalent to that of the cable ladder.
  • Easy-to-cut. No burrs or sparks when cutting.

Design

  • Sturdy profiles made of high quality extrusion with the definitive form of use and solid walls. No adhesive, rivets or screws to fix rungs to the side rails, increasing the durability of the ensemble.
  • Junctions with thickness equal or higher than the side rails.
  • Profiles compatible with the standard cover and divider of Unex insulating cable tray 66.
  • Colour: Grey RAL 7035.

Mounting instructions

  • To fulfil the characteristics defined herein, the installation must be carried out in accordance with the manufacturer`s assembly instructions provided in the main product packaging and also available on the website www.unex.net.
