Communication base stations are often located in high altitude, open spaces, and exposed environments, making them highly susceptible to direct and induced lightning strikes, resulting in equipment damage, communication interruptions, and economic losses. According to the GB50689-2011 Lightning Overvoltage Protection Specification for Communication Bureaus (Stations), Haipeng Xin has developed a fully integrated surge protection scheme covering the power system, signal system, and antenna feeder system, providing high reliability lightning protection for 5G/4G macro stations, micro stations, integrated cabinets, and tower sharing stations.
The scheme adopts a hierarchical protection architecture: the first level high current SPD on the power side discharges the main lightning current, the second level fine SPD reduces residual voltage, and the third level DC/precision lightning protection protects core equipment such as BBU and RRU; Signal side coverage network port POE、 Full interface protection for coaxial, video, industrial control, etc; The antenna feeder side provides dedicated protection for tower top low-noise amplifiers, microwave, timing, and GNSS systems.
The complete set of products has the characteristics of high throughput, low residual voltage, fast response, remote signaling alarm, hot plugging, and wide temperature adaptation. It is matched with backup protectors and decouplers to achieve perfect inter level matching, effectively reducing lightning failure rate and ensuring stable operation of base stations 7 × 24 hours a day. It is a standard safety solution for operators and railway tower companies when building stations.
Product Features:
Third level protection, full link coverage: power supply+signal+antenna feeder systematic protection, adapted to the full functional areas of base station power distribution and information processing.
Multi scenario adaptation: supports different base station forms such as macro stations, integrated cabinet stations, and tower sharing stations.
Precise protection for critical nodes: covering ports of devices such as mains power, RF, transmission, timing, microwave, satellite antennas, etc.
High reliability protection performance: high current, low residual voltage, fast response, with overheating/overcurrent protection and degradation alarm.
Wide temperature and weather resistance: stable operation at -40 ℃~+85 ℃, suitable for harsh environments with high thunderstorms and high salt spray.
Convenient operation and maintenance: supports hot plugging, remote signaling alarms, comes with decouplers and counters, easy to deploy and maintain.
Compliance standards: Compliant with GB50689-2011 Communication Lightning Protection Specification, the product model and scheme architecture match the requirements of the three major operators and tower centralized procurement, and can be directly used for project implementation.
