   The GJYFXTW53 cable is made by placing several coloured fibres in LSZH miniature cluster tubes and spirally twisting them around a non-metallic tensile element (aramid) to form a stable circular core, Which is wrapped in an outer longitudinal sheath of high-strength aramid yarn and water-blocking tape and then extruded with a LSZH inner sheath, and the outer longitudinal layer is wrapped with water-blocking tape, ripcord and plastic-coated steel tape for waterproofing and easy peeling effect, with a parallel steel wire on each side of the steel tape, then the outer sheath is extruded with a layer of polyethylene material.

Double sheath structure, with good resistance to lateral pressure;

Containing multiple strands of high strength aramid fibers with excellent tensile resistance;

High density and small outer diameter for indoor/outdoor switching with excellent stripping effect;

Two parallel metal reinforcements ensure the tensile strength of the cable;

Symmetrical ripcords improve construction efficiency and reduces stripping time;

Symmetrical ripcords improve construction efficiency and reduces stripping time;
