Wind Farms

Protection of cables and drainage for high-performance wind farms

The Challenge

Wind farms face elevated terrain, strong winds, and unstable soils. The underground infrastructure must withstand decades of operation with minimal maintenance in hard-to-reach locations.

Techdreno protects medium-voltage cables connecting wind turbines to substations, and drains tower bases to prevent erosion and structural instability.

Our HDPE pipes are lightweight, flexible, and UV-resistant – ideal for rapid installation on rugged terrain and remote areas from urban centers.

Techduto Solutions for Wind Farms

Recommended lines, uses, and key features

Line	Main Use	Difference
HDPE DW	Passage of MT cables between towers	Smooth interior → fast passage of heavy cables
HDPE NBR	Buried sections and crossings	Flexible, lightweight, wide range of diameters

Challenges & Solutions

How Techduto solves each challenge in Wind Farms

Cables MT and fiber exposed to impact and moisture

Techduto DW with 1,000N of compressive strength and smooth interior protects cables against crushing and moisture.

Flooding platforms and bases

Techdreno DW combines water collection through the perforated exterior with fast drainage through the smooth interior, eliminating accumulation.

Eroded access routes

Techdreno KC with integrated filter wrapping eliminates the need for a separate geotextile — faster installation.

Maintenance in remote locations

25+ year lifespan with HDPE resists corrosion and UV — drastically reduces corrective maintenance.

FAQ

Common questions about Wind Farms

The Techduto DW with smooth interior is ideal for heavy MT cables — the smooth interior facilitates passage and reduces pulling force. For short sections and crossings, the Techduto NBR is an economical alternative.

With Techdreno NBR or DW installed around the foundations, directing water to safe discharge points. This prevents erosion and maintains structural stability of the tower.

Yes. HDPE pipes are buried and not directly affected by wind. The material resists UV, soil chemical agents and extreme thermal variations.

Yes. With our own logistics and factories distributed throughout Brazil (SP, PE, MT), we make fractional deliveries according to the project schedule, including in difficult-to-access locations.
