Medium Duty Angle Tower
Product Overview
The Medium Duty Angle Tower is a self-supporting steel lattice tower installed along high-voltage trunk routes to balance lateral tension at line deviation points.
Core Features
Medium-profile structural steel sections matched to design lateral loads at 30°–60° line angles.
Main truss system reinforced with inverted K-bracing to maintain geometric stability under peak asymmetric loads at curve nodes.
Designed with a 1.5 safety factor to sustain multi-circuit conductor loads under 60° maximum deviation conditions.
All joints configured with double-bolts and rigid lock washers to reduce fastener loosening under long-term aeolian vibration.
Suspension points use Q420B high-strength steel and double-shear plates to prevent bearing and shear failure under peak loads.
86 μm hot-dip galvanized coating provides corrosion protection for structural members in high-humidity and boundary grid environments.
