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.
