RECOMMENDATIONS FOR THE SELECTION OF ACCESSORIES AND DUCTS
The technical information presented here is for reference purposes only. Actual dimensions and construction details will only be available with the test reports for each manufacturing order. For the selection of accessories and/or ducts, it is recommended to measure directly on the actual dimensions of the cable using the appropriate methods and instruments. Centelsa by Nexans will not assume any responsibility for the selection of such elements.
