产品名称:

(GDTS) Hybrid Optic And Electric Composite Cable

The fibers,250μm,are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. The cable core is FRP or metallic strength member( some structures need add PE as bedding layer in the strength member). Electric wires and tubes (and fillers) are stranded around the strength member into a compact and circular cable core. The cable core is filled with the filling compound to protect it from water ingress. After two sides PSP are longitudinally applied over the inner sheath ,the cable is completed with PE or LSZH outer sheath.

lHave good flexibility and mechanical properties

lPhotoelectric integration, fully conserve pipeline resources

lThe cable part and the optical cable part are relatively independent structure, which is convenient for the introduction, the lead out and the connection of the installation

lWill power lines, telephone lines, TV lines, cable, monitoring line, data line and other network, save the cost

lOptical cable diameter and bending radius are small, in the next small space also can freely install compatible optical signal transmission and power transmission at the same time
