Self Supporting Angle Tower
Product Overview
The Self Supporting Angle Tower is a four-leg lattice steel transmission tower without guy wire anchoring, designed for high-voltage line angles, crossings, and corridor-constrained installations.
Core Features
Four-leg rigid lattice structure provides independent load-bearing capacity without the need for external guy wire anchoring.
Widened base spacing distributes wind load paths and reduces stress concentration on individual legs.
High-strength angle steel members increase sectional capacity, maintaining stability under extreme wind and unbalanced loading conditions.
