Protect and Route Cables

Corrugated HDPE conduits for mechanical protection of electrical, telecom and fiber optic cables

Protect and Route Cables

The Challenge

Buried electrical, telecommunications and fiber optic cables need mechanical protection against impacts, moisture and interference. Without adequate protection, corrective maintenance is frequent and costly.

Techduto DW is a double-wall corrugated pipe designed specifically for underground cable protection. With a smooth interior for easy cable pulling and corrugated exterior for mechanical strength, it is the preferred solution for energy utilities, telecom companies and renewable energy parks.

Challenges and Solutions

How Techduto addresses each challenge in Protect and Route Cables

Mechanical damage

Techduto DW with corrugated outer wall absorbs excavation impacts and soil pressure, shielding your cables.

Water infiltration

Techduto Tape seals all connections with permanent adhesion, preventing water and moisture from reaching cables.

Repair cost

With Techduto NBR and DW, locating and replacing cables is simple — just pull through the smooth interior without digging a new trench.

How We Apply It

Techduto methodology in 3 steps

1

Design

Definition of route, depth and conduit diameter based on the total cross-section of cables to protect.

2

Installation

Trench opening, Techduto DW laying and cable pulling through the smooth interior — up to 30% faster.

3

Sealing

Connection sealing with Techduto Tape, backfill and compaction for permanent protection.

Frequently Asked Questions

Common questions about Protect and Route Cables

Techduto DW has a double wall: corrugated exterior for mechanical strength and smooth interior to facilitate cable pulling. Rigid conduits are heavier and more expensive.
Yes. Techduto DW is the most widely used solution for cable protection in renewable energy parks in Brazil, meeting NBR standards.
The diameter depends on the total cable cross-section. The practical rule is that cables should occupy no more than 40% of the conduit's internal cross-section.
Yes. The Techduto NBR line is certified per ABNT NBR 15715:2020. Techduto participated in the technical drafting of this standard and maintains continuous compliance testing.
Seal all joints with Techduto Tape (HDPE-specific adhesive tape), which creates permanent waterproof sealing against water, moisture and insects.
Standard NBR is for buried sections without sun exposure. UV line has anti-UV additive for sun-exposed sections (tracker, string box, rooftop). AC line has flame-retardant additive required near inverters, transformers and electrical rooms.
