Packing &transportation

Î Zhongtian Hitachi highly foamed polytehne dielectric coaxial cables are packed in carton,

coiled on wooden reel. Both carton and wooden reel are not returnable. When the cable is

ordered with connector, the connector is assembled in the end of the cable. During

transportation, right tool should be used to avoid damage the package, and handle carefully.

Î When cables are in the process of transportation, storage and usage, some notice should be

taken: Cables should be protected from moisture; Cables should be kept away from high

temperature condition and spark; Cables should be protected from overbending and crushing;

Cables should be protected from mechanical damage.
