Extraco engineers non-conductive, double-helical wound Glass Reinforced Polymer (GRP) utility poles for high-voltage transmission lines (11kV to 33kV) and high-durability municipal street lighting.
High-integrity Glass Reinforced Polymer utility poles manufactured via high-tension double helical winding.
Engineered for high-voltage transmission lines (L.T., 11kV, 22kV, and 33kV) complying with REC, ASCE-104, and ANSI C136.20 standards.
Suitable for street lights, garden lighting, and general industrial lights with top or side arm configurations.
Can be buried directly in acidic or alkaline soils without cathodic protection, or mounted via precast concrete anchor bolts.
Technical mechanical and electrical evaluation of Extraco GRP poles versus traditional steel and concrete.
| Property / Parameter | Extraco GRP Composite Poles | Steel Poles | Prestressed Concrete (PCC) |
|---|---|---|---|
| Electrical Conductivity | Non-Conductive (30 kV/mm Dielectric)/td> | Highly Conductive (Safety risk) | Conductive when wet |
| Weight / Density | Ultra-Light (1/4 weight of steel) | Heavy (Requires cranes) | Extremely Heavy |
| Corrosion Resistance | 100% Rust & Chemical Proof | Rusts; requires galvanizing | Cracks & spalls over time |
| Tensile Strength | 250 N/mm² | High | Moderate |
| Service Life & Maintenance | 50+ Years (Zero Maintenance) | 15 - 20 Years (Frequent painting) | 20 - 25 Years |
Manufactured under strict ISO 9001:2015 QA/QC protocols complying with ASCE, ANSI, AASHTO, and ASTM standards.
Recommended practice for Fiber Reinforced Polymer products for overhead utility lines and pole structures.
Structural support standard for highway luminaires, traffic signals, and reinforced thermosetting plastic poles.
