제품 설명
70FT Multi Section Q420B Octagonal Galvanized Electric Steel Pole 1500KGF for 132KV Transmission
Yixing Hongxin Illumination Facilities Co., Ltd. presents its flagship 70FT multi-section octagonal galvanized electric steel pole, the highest-capacity standard offering rated at 1500KGF for 110KV-132KV transmission and substation structures. This pole represents the culmination of Hongxin's 25+ years of manufacturing expertise, combining Q420B ultra-high-strength steel with a precision four-section bolted flange assembly system to achieve transmission-class load ratings previously only attainable with lattice towers.
Key Features
- 1500KGF Maximum Rating: The highest standard load rating in Hongxin's catalog, designed for 132KV transmission dead-end structures, long-span crossings exceeding 400 meters, and substation gantry applications where structural demands are extreme.
- Q420B Peak-Performance Steel: 420 MPa minimum yield strength enables transmission-class load ratings with pole weights manageable for standard erection equipment, avoiding the logistics premium of lattice tower alternatives.
- Four-Section Precision Assembly: Each flange interface is CNC-machined to tight flatness and parallelism tolerances, with Grade 10.9 galvanized high-strength bolts providing rigid, maintenance-free structural connections.
- Comprehensive Corrosion Protection: Full-immersion hot-dip galvanization coats interior and exterior surfaces, with an optional duplex coating system (galvanized plus epoxy/polyurethane topcoat) available for extreme marine and industrial environments.
- Foundation Flexibility: Custom base plate designs accommodate embedded anchor bolt cages, cast-in-place piers, and precast foundation blocks, with structural calculations provided for all foundation types.
- Full-Scale Prototype Validation: Every new pole configuration undergoes cantilever load testing at Hongxin's in-house test facility, with strain gauge instrumentation verifying that actual structural behavior matches analytical predictions.

Applications
The 70FT multi-section transmission pole is the definitive solution for 132KV transmission corridors, grid substation entry and exit structures, long-span river and valley crossings, and wind farm or solar farm collector substation tie-lines. Where lattice towers are too visually intrusive or require excessive land area, this monopole structure provides equivalent electrical clearance and mechanical capacity in a compact footprint. The pole supports twin, triple, and quad bundle conductor configurations, dual OPGW earth wires, and all standard 132KV air-insulated switchyard equipment. Hongxin's engineering team provides complete structural design packages including finite element analysis, foundation design calculations, and construction method statements for client approval.
Packaging & Quality Assurance
Four-section pole sets are individually wrapped with weather-resistant film, flange faces treated with anti-corrosion compound, and packed in heavy-duty steel-crated bundles for ocean freight. Complete documentation suite: Q420B mill certificates, flange machining and fit-up reports, robotic weld procedure and NDT records, ISO 1461 galvanization certificates, and full-scale prototype load test reports with strain gauge data. Third-party inspection by recognized international agencies is standard for transmission-class projects. 12-month manufacturing warranty. Minimum order: 5 pieces. Delivery: 45-60 days for standard configurations.
