Chengdu Shuangliu International Airport, as an important aviation hub in the central and western regions of China, undertakes a large number of flight takeoffs and landings every day. With the passage of time, some of the lighting circuits at the airport have gradually aged, and the stability and safety of the use of lamps are facing challenges. In 2023, in order to ensure the reliability of the airport's lighting system and improve operational efficiency, the airport management department decided to upgrade the current old lighting circuits.
Among many suppliers, Shanghai Airsafe Airport Equipment Co., Ltd. stood out with its unique technological advantages and good market reputation. Airsafe got the tender to supply all the navigation aid lighting equipment for those 6 old lighting circuits. The special highlight of this project was that the new type of primary cable connectors and isolation transformers developed by Airsafe Company were installed in all 6 circuits.
The primary cable connector of Airsafe is a sealed cavity design and adopts a unique silicone injection process. The construction operation is simple, and people can handle the on-site assembly skill easily without undergoing strict training. More importantly, it greatly improves the quality of on-site construction and guarantees the maintenance of high insulation resistance performance of the lighting circuit in the later stage. During this period of formal operation, the technicians of Airsafe came to the site from time to time to collect insulation data of the circuits. All the data prove that the insulation resistance of the circuits using Airsafe's cable connectors has always remained at a high level, fully meeting the requirements of the airport for the insulation resistance of the circuits and achieving the expected goal of the circuit transformation.
This year, Chengdu Shuangliu International Airport had another project and they did not hesitate to choose Airsafe's products again for those circuits. Among the 4 runway circuits currently under construction, all have used Airsafe's primary cable connectors. This decision is not only a trust in Airsafe's products, but also an affirmation of our high-quality products.
The low insulation resistance of the circuits has solved the long-standing problem that has plagued the airport. Many airport circuits operate at several megohms or even several hundred kilohms, seriously threatening the safe operation of the airport. With the wide use of LED navigation aid lamps, the requirements for the insulation resistance of the circuits are getting higher and higher. Especially with the introduction of advanced ground guidance systems, the problem of low insulation resistance of the circuits has become more prominent. The primary cable connector of Shanghai Airsafe Airport Equipment Co., Ltd. has completely solved this problem and provided a guarantee for the safe operation of the airport.
