Double Circuit Suspension Tower
Product Overview
The Double Circuit Suspension Tower is a steel lattice transmission structure designed to support two independent transmission circuits within a single transmission corridor.
Product Features
Manufactured from Q355B and Q420 high-strength structural steel, designed for wind speeds up to 45 m/s and radial ice loads up to 20 mm.
Incorporates a double-tier vertical suspension cross-arm arrangement for double-circuit conductor configuration.
Utilizes a wide-base four-legged lattice structure with an enlarged foundation reaction span.
Produced using CNC punching and angle-cutting processes to ensure assembly accuracy of connection holes and flange joints.
Hot-dip galvanized in accordance with ASTM A123, with an average zinc coating thickness of not less than 86 μm, meeting outdoor corrosion protection requirements for transmission line applications.
