View Technical DataGlobal Transition in Municipal Solar Illumination & Smart Infrastructure
Analyzing key drivers in clean energy adoption, carbon-neutral urban grid expansion, and advanced photovoltaic technology integration.
Next-Gen PV Conversion
Transition from P-type PERC to N-Type TOPCon and Heterojunction (HJT) solar cells offering ultra-high conversion efficiencies exceeding 24.5%, maximizing power generation even under low diffuse light and heavy overcast conditions.
Thermodynamic LiFePO4 Systems
Deprecation of legacy lead-acid and ternary gel batteries in favor of structural Lithium Iron Phosphate (LiFePO4) storage, delivering 4,000+ deep-cycle lifespans and continuous operations across extreme thermal thresholds (-30°C to +65°C).
IoT Centralized Telemetry
Integration of LoRaWAN, NB-IoT, and Zigbee wireless protocol mesh networks within solar charge controllers to enable real-time dimming schedules, automated predictive maintenance, and localized energy balance optimization.
Information Gain: Quantitative Impact of Energy Autonomy
Deploying engineered, high-efficacy (≥220 lm/W LED chips) off-grid solar street lighting eliminates carbon emissions by approximately 1.25 metric tons of CO2 per pole annually compared to conventional grid-connected high-pressure sodium (HPS) fixtures, while entirely mitigating civil trenching and underground cabling capital expenditure costs (averaging $25-$40 per linear meter in urban infrastructure contracts).
Integrated Industrial Fabrication & Quality Control
Operating a vertically integrated 100,000 m² industrial facility in Jiangsu, Yangzhou Xintong Traffic Equipment Group controls every phase of steel pole rolling, submerged arc welding, hot-dip galvanizing, and electro-optical assembly.
Metallurgical Engineering & Pole Forming
Utilizing high-tensile structural steel raw plates (Q235B, Q355B, and European Standard S355JR) sourced exclusively from state-audited mills with EN 10204 3.1 material test certificates. Our facility features a 16-meter CNC hydraulic press brake capable of executing single-seam longitudinal pressing for conical, octagonal, dodecagonal, and customized polygonal pole geometries.
- Single-piece longitudinal automatic submerged arc welding (SAW)
- Yield strength parameters verified up to 355 MPa
- Full internal and external continuous seam integrity per AWS D1.1 structural welding standards
Corrosion Defense: Hot-Dip Galvanizing & Duplex Coating
Every steel structure undergoes acid pickling, fluxing, and immersion into a 99.99% pure molten zinc bath maintained at 450°C in compliance with ISO 1461 and ASTM A123. This produces a metallurgically bonded zinc-iron alloy layer exceeding 86 µm in thickness (average 610 g/m² zinc density), delivering a maintenance-free service life exceeding 25 years in harsh C4/C5 marine and industrial environments.
- Optional electrostatic thermosetting pure polyester powder coating
- Adhesion performance validated via cross-hatch cross-cut tape test (Class 0)
- UV-resistant outdoor finish resistant to salt spray testing exceeding 1,500 hours (ASTM B117)

Deep Dive: Split-Type vs. Integrated All-In-One Solar Street Lighting
Selecting the optimal technical route for municipal infrastructure projects requires evaluating thermal profiles, optical distributions, autonomy requirements, and local solar peak sun hours (PSH).
1. All-In-One (Integrated) Solar Systems (XT-YTH Series)
Integrates the PV panel, high-lumen LED optical engine, LiFePO4 battery pack, and MPPT intelligent controller into a unified die-cast aluminum chassis (IK10 & IP66 rated).
Engineering Advantage: Zero external wiring connectors; ultra-fast mechanical installation requiring under 10 minutes per pole; lower wind resistance surface area.
2. Split-Type Modular Solar Systems (XT-DT Series)
Separates the PV generator, LED luminaire head, and battery storage. The photovoltaic module is mounted on an adjustable bracket allowing optimal tilt angle alignment (0° to 60°) based on geographical latitude.
Engineering Advantage: High power output (up to 150W LED / 400W PV); underground IP68 battery placement maintains stable thermal mass during freezing or extreme heat conditions.
Optoelectronic Precision: Professional DIALux Simulation Support
XINTONG engineers utilize DIALux Evo photometric software to model road surface luminance (cd/m²), overall uniformity (U0), longitudinal uniformity (Ul), and threshold increment glare (TI %) according to EN 13201 and IESNA RP-8 street lighting classes. Customized Batwing optical lens distributions (Type II, Type III-M) eliminate dark spots between poles while expanding pole-to-pole spacing up to 45 meters, drastically reducing total infrastructure equipment requirements.
Wind Load Resistance & Structural Mechanical Engineering
Ensuring absolute stability and public safety in coastal typhoon zones, desert wind corridors, and high seismic areas.
AASHTO LTS-6 Compliance
Calculated structural resistance based on Standard Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals. Certified to withstand gust wind speeds up to 60 m/s (216 km/h) with maximum top-pole displacement under 2.5% of total height.
Finite Element Analysis (FEA)
Every non-standard lighting structure, high mast tower (15m to 40m), and multifunctional smart pole undergoes FEA computer simulation to identify stress concentrations at arm junction welds, door opening cutouts, and base flange anchor bolt connections.
Anchor Cage Geometries
Complete supply of J-bolt or straight anchor bolt cages engineered with high-strength grade 8.8 steel studs, zinc-plated threads, positioning template plates, and double nut/washer hardware for precise vertical plumb adjustment during foundation pouring.
