Techduto DW
Cable protection with smooth interior — 1,000 N and frictionless passage
Double-wall HDPE conduit for telecommunications, fiber optics, and electrical networks. Smooth interior for friction-free cable routing, 1,000 N tensile strength, and compliance with NBR 15715.
The Problem
Standard corrugated conduits make it difficult to run cables through them—the rough inner surface causes friction, damages fiber-optic coatings, and increases installation time and costs. In telecommunications and data centers, any damage to the cable can take down entire networks and result in fines for downtime.
The Techduto DW Solution
Techduto DW combines a corrugated exterior (with a tensile strength of 1,000 N) with a completely smooth interior (for friction-free cable passage). Reduce cable pulling time, eliminate damage to the cable jacket, and install at a shallower burial depth thanks to the greater rigidity of the double-wall design.
