Custom Traffic Signal Cabinet Manufacturer in China

A Traffic Signal Cabinet is an outdoor enclosure that houses all the essential electronics and control systems used to manage traffic lights at intersections, highways, and pedestrian crossings. Its primary role is to protect controllers, relays, and wiring from environmental damage, unauthorized access, and operational failures.

How Does It Work?
The cabinet receives power from the city grid and distributes it to traffic lights and connected sensors. Inside, it contains a traffic controller, which processes inputs from vehicle detectors, pedestrian buttons, and timing schedules. These inputs are analyzed in real time to manage signal changes, ensuring safe and efficient traffic flow.

Cooling components like fans, filters, or air conditioning regulate internal temperature, preventing overheating of critical electronics. Terminal blocks and control transformers help manage power distribution and ensure stable voltage for sensitive components.

Security features such as locks, thermostats, and cable management systems ensure the cabinet operates in all weather conditions and prevents unauthorized tampering. Remote monitoring systems can also be integrated, allowing city engineers to diagnose and manage signals without field visits.

Wholesalers and distributors benefit from cabinets designed with standardized mounting, easy installation, and scalable features that reduce maintenance costs. Custom designs allow adaptation to specific city requirements, such as NEMA 3R compliance, advanced network communication, or solar backup integration.
