In the operational support system of the new control tower at an international airport in Guiyang, the lightning protection and surge protection system serves as a critical component in ensuring the stable operation of aviation communication, power control, and navigation equipment. Since its commissioning in 2012, the DK-220AC40/D30 power surge protective device (SPD) provided by Dikai company has withstood the severe tests posed by the complex plateau climate and frequent thunderstorms over the past 13 years. To this day, its performance remains stable and reliable, fully demonstrating the exceptional quality and long-lasting industrial design philosophy of Dikai’s products.
To meet the higher safety and intelligent requirements of modern airports and national military units for lightning protection systems, Dikai Technology launched a new-generation product in 2025—the DK-40 D30/D10 power surge protective device (SPD). While retaining the stable and reliable characteristics of the older model, the new product achieves comprehensive upgrades in safety performance, intelligent monitoring, and maintenance convenience:
· Thermal Control Circuit-Breaking Technology: Equipped with a built-in thermal trip device, it automatically disconnects in case of abnormal component temperature rise or after extreme lightning strikes, preventing overheating and fire hazards, significantly enhancing safety levels.
· Multi-Stage Protection Circuit Design: Utilizes a new-generation composite lightning protection module for faster response and lower residual voltage, providing more refined protection for precision electronic equipment.
· Status Visualization and Audible/Visual Alarms: Features working/fault indicator lights, lightning strike counters, and fault alarm bells, enabling maintenance personnel to monitor the SPD’s operational status in real time.
· Plug-and-Wall Modular Installation: Supports quick plug-in and removal for maintenance, reducing inspection time and improving equipment operation and maintenance efficiency.
