Ribbon GYDTS Duct, Aerial Optical Cable

Product Description:

The structure of GYDTS (outdoor optical cable used for telecommunication with metallic central strength, Steel-PE cementing sheathed, loose and layer-stranded tube style,) is covering the inner-fulfilled waterproof compound loose tube, which is made of high modulus plastic, with the single mode and multi-mode optical fiber. There is a steel wire in the middle of the optical cable core. For some optical cables with

certain number of core, the steel wire should be a steel stranded line covered with a tight pack of polyethylene (PE).

The compact and round shape cable core is a combination of the loose sleeve pipe (gasket for packing) and center-strengthened core, the gap in the cable core is filled with water retarding compound. It is cabled after the plastic-plated steel tapes has been covered of PE sheath.

For meeting to standard IEC60502
Longitude water proof
At many circumstances, the life of XLPE insulated cable is influenced by moisture, it should adopt a additional structure to proof water when outer sheath is broken, then water can not get in shield area. We can do by this way:
Use water proof powder in shielding area
Use water proof tape, and extrude bedding on the shielding layer
Use water proof in the inside and outside of metal tape screen
