HDPE Corrugated Pipe — Techduto NBR
Cable protection certified to NBR 15715 — 750 N and a service life of over 75 years





Flexible corrugated HDPE conduit compliant with NBR 15715, with a tensile strength of 750 N, an integrated cable guide, and a service life of over 75 years, designed to protect electrical, telecommunications, and fiber-optic cables. Also available in special UV and AC lines formulated for solar power plants.
The Problem
Metal and concrete conduits used to protect cables are susceptible to corrosion in acidic soils, require costly maintenance, and have a limited service life. Their heavy installation requires specialized equipment and larger crews, increasing both costs and project timelines.
A Solução HDPE Corrugated Pipe
Techduto NBR eliminates corrosion, withstands impacts of 750 N, and has a service life of over 75 years. Installation is 35% faster than with metal alternatives—the pipe is lightweight and flexible, and the sleeve and O-ring connections require no special tools. Available in UV-resistant versions for solar power plants and with an integrated cable guide.
Diferenciais que se provam
Special UV and AC lines: engineering polymer formulated for years under the sun at photovoltaic plants—where ordinary pipe fails.
Reinforced anti-UV, not the minimum
All HDPE has anti-UV, but only until it's buried. The UV line adds an extra layer, for years of direct sun under the trackers.
Certified flame-retardant
Certified flame-retardant additive, required at plants and power cabinets. The standard pipe doesn't have it.
Field-proven across Latin America
UV and AC lines at dozens of plants: Brazil, Chile, Argentina, and Mexico.
Above the NBR 15715 standard
Compression up to 750 N and a reinforced additive for years of direct sun.
