Problems solved by technology

[0004] Although this kind of airport navigation light cable has good shielding effect, excellent anti-interference performance and insulation performance, the all-round waterproof technology ensures that the cable can be used safely in rainy water, and when the cable fails, it can be well grounded and the allowable short-circuit current is large. , safe to use, suitable for airport lighting cables, but often after long-term use, the exterior will be damaged, and once the damage occurs, it is easy to affect the inner core of the cable, resulting in short circuit or open circuit of the cable
