Traditional street light and garden light pole wiring has long been plagued by inherent drawbacks, including disorganized internal wiring, fixed protection configurations, and inefficient on-site installation. To resolve these universal industry pain points for outdoor lighting projects, we have independently developed a modular dedicated junction box for light poles.
Crafted with high-strength PA66 integrated injection molding and equipped with a standard 35mm DIN rail structure, this junction box supports flexible combination of various electrical protection components. The innovative plug-in input terminal design perfectly adapts to the construction standards of smart street light projects, accommodates large cross-section cables, and provides a professional and reliable in-pole power distribution solution for outdoor lighting systems.
2. Common Industry Pain Points of Traditional Street Light Wiring
- The narrow internal space of light poles leads to scattered installation of circuit breakers, SPD surge protectors and protective devices, resulting in messy and unstandardized wiring layout.
- Conventional fixed structural designs cannot meet customized protection requirements for different engineering projects and client standards.
- Traditional hard-wired terminals cause slow on-site wiring, high connection error rates, and inconvenient inspection and component replacement during later maintenance.
- Ordinary plastic enclosures deliver poor UV resistance and aging resistance, prone to damage under long-term outdoor exposure.
- Conventional terminals have limited cable capacity, failing to support power supply demands of high-power smart multi-functional light poles.
