Three-Bundle Running Board Keeping Conductor Geometry Stable

Product Overview

Stringing three sub-conductors in a single pull demands more than a strong hook: every meter of the run, the three lines must hold an identical triangular pattern or they will slap together in gusts. The SZ3A head board locks the bundle into a rigid triangle, letting crews pull 100-180kN loads with the geometry fixed from drum to tower. Its anodized aluminum body shrugs off UV, rain and salt, while reinforced stress points absorb the shock of heavy pulls. Pre-assembled modules with color-coded parts cut rigging time, making the board a dependable partner on EHV and UHV projects.

Technical Specifications

Applications

· Pulling three sub-conductors simultaneously on EHV/UHV lines

· Holding a fixed triangular pattern between adjacent sub-conductors

· Preventing wind-induced clashing during long-span stringing

· Rigging large cross-section triple-bundle conductors

Product Advantages

· Fixed Triangular Geometry — the three conductors are held at a constant relative angle for the whole pull, eliminating spacing drift between sub-conductors.

· Load-Ready Frame — high-grade aluminum with reinforced stress points carries 100-180kN working loads without fatigue failure across repeated pulls.

· Weatherproof Finish — anodized surfaces resist corrosion and UV degradation, keeping the board field-worthy for years.

· Crew-Friendly Rigging — color-coded, pre-assembled modules assemble quickly on the tower; smooth edges and non-conductive options protect insulation.
