Airport Cable
The cable for airport guarantees the reliability and safety of airport electrical operations as an important part of the electrical system. If airport power lines fail, can cause massive power outages and seriously impact normal aircraft flights.
ZMS offers a range of reliable electrical cable products for airports. Among them, find cables for airfield lighting, airport runway cables, airport flame retardant and fire resistant cables, etc.

Airfield Cable Troubleshooting
Airport navigation lighting plays a very important role in the safe take-off and landing of aircraft.. So, the normal operation of navigation light cables is a fundamental part of the overall system.
Currently, most airports use the method of direct burial to lay cables navigation lighting. This method exposes airport cables directly to the environment. The external work environment of airports is very harsh and is often damaged by various factors, as temperature variations, animal rodents, etc.
At the same time, airport cables are laid in long lengths and are widely distributed. Thus, if the cables of the airport navigation lighting system are not repaired in time, this could lead to the resumption of flights or even the closure of the entire airport.
Once the faults have occurred, it is very difficult to diagnose and fix, making cable problems an ongoing problem for many airports. So, How can you improve the safe operation of airport cables??
Method of Diagnosis of Faults in Cables for Airports
Main circuit failure in the navigation light cable is diagnosed by shorting the core of the cable to the metal shield on the power supply.. At the same time, use a multimeter on the end to be tested to measure the resistance between the core and the cable shielding. If the measured value is infinity, there is a cut in the circuit. If the measured value is greater than the normal DC resistance of the cable by a factor of 2 or more, can be judged as a failure without breakage.
Example of Diagnostic Applications
In the course of test operations at an airport, navigation lighting lines failed, causing some of the center line lights to go out. The airport quickly adopted an emergency plan and carried out emergency repairs to the faulty lights..
The repairman first used a 2500V megohmmeter on the end of the circuit wire and found that the resistance to ground was approximately 0. Posteriorly, the DC resistance of the cable was measured with a multimeter to be 88Ω, which allowed to conclude that a ground fault had occurred. The normal resistance of the cable is 35 Oh. Therefore, it was concluded that the cable could also have an open circuit fault, which led to the decision that the cable had a compound failure.
The types of faults that occur in the cables of the airport navigation lighting system should be reasonably analyzed. And faults must be analyzed and eliminated in time. This performed?to an important role in ensuring the normal and safe operation of the airport.
