Release time: 2026-06-09
Outdoor corrosion protection: Hot-dip galvanized cable trays (zinc layer ≥100μm), salt spray resistance ≥5000h; large spans (9–12m) for bridges/pipe galleries to reduce support structures.
Pipe gallery integrated cabling: ladder-type for power (heat dissipation), trough-type for communication (shielding); layered laying, strong and weak currents isolated.
Bridge seismic resistance: Q345D high-strength steel + prestressed crossbars, deformation <5mm under a category 12 typhoon, lifespan ≥30 years.
