GYXTW single-armored cables feature central loose tube wrapped with a layer of PSP longitudinally, excellent crush-resistant performance. Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight.Direct buried cable can be buried directly ground in a trench or using a vibratory with great water-blocking and moisture-proof performance, it also has good crushing performance. With metallic central strength offers ease of location while dielectric grounding issues.Duct cables are typically buried, and then the cables are air-blown, jetted, pulled or pushed into the duct. It features high tensile strength and excellent waterproof protection. Usually armored cables are installed under floors in data centers or in rocky soil, as well as to prevent rodent penetration.Aerial Cables are for outside installation on poles where consideration must be given to continual tension from the cable weight as well as wind and ice loads. It can be helically lashed to a messenger or another cable. Self-supporting cables use special hardware to handle the installed tension on the cables caused by the weight of the cab. Access network Bureaus network Metropolitan network Aerial & conduit/duct application Two parallel steel wires are placed at the two sides of the steel tape, to ensure tensile strength. The cable is completed with a single polyethylene (PE) sheath. This is suitable for aerial or duct environment for communication between bureaus, metropolita.
