Partially Prestressed Concrete Pole 350 x 12 m
Heavy-duty centrifugally spun partially prestressed concrete pole (350 mm top diameter, 12 m overall length) engineered for high-load feeder lines, substation incoming gantries and dead-end/angle structures.
- Prestressed steel wire combined with spiral reinforcement to control cracking
- Large 350 mm top diameter for heavy conductor bundles and multi-circuit cross-arms
- Centrifugally spun and steam-cured in our Tongxu production base
- Load testing is carried out on our in-house pole test benches
