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.

A Solução Techduto DW

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.

Frequently Asked Questions

Dúvidas comuns sobre o Techduto DW — Cable Protection

Techduto DW features a double-wall design (corrugated exterior + smooth interior) with 1,000 N of impact resistance, making it ideal for friction-free cable routing. Techduto NBR is a single-wall corrugated conduit with up to 750 N of impact resistance, suitable for general cable protection applications.
Yes. The smooth interior eliminates the friction that cables experience in the grooves of standard corrugated tubing. This protects the optical fiber coating and significantly reduces installation time.
Techduto DW is available in 110, 160, and 200 mm diameters, supplied in 6-meter lengths in accordance with NBR 15715.
Techduto DW is primarily designed for cable and telecommunications protection. For fluid conveyance, please consult our technical team for recommendations on the most suitable product for your project.
Yes. With an impact resistance of 1,000 N, the Techduto DW can be installed under highways and in areas with heavy traffic, provided the recommended minimum burial depth is observed.
Yes. HDPE is naturally resistant to corrosion and to chemical and biological agents in the soil. It has a service life of over 50 years without requiring maintenance or replacement.
