PETROLEUM FILLED QUADED RAILWAY SIGNALING CABLES, ARMOURED PE SHEATH WITH A RF OF 0,3. ADIF SPECIFICATION Telecommunication cable Impact Resistant SPECIFICATIONS Construction: ADIF ET-03.365.051.6 2nd edition DESCRIPTION AND APPLICATION Cables from 1 to 27 star quads, conductors of 0.9 and 1.4 mm, polyethylene insulated. The quads are stranded in layers to form the core which is filled with petroleum filling compound and then protected by an anti inductive sheath with a reduction factor of 0.3. They are used as telecommunication cables or in rail circuits, especially in rail infrastructures when protection is required against the induction of high voltage lines. For installation in ducts or directly buried. The cable is rodent resistant. CONSTRUCTION • Conductors: Annealed copper wire, 0.9 and 1.4 mm in diameter. • Insulation: Solid polyethylene. • Cabling element: Star quads. • Core formation. Stranded in layers. • Filling compound: PE jelly. • Core wrapping. Dielectric tape longitudinal applied with overlap. • Inner sheath: Polyethylene. • Cable screen. Corrugated copper tape longitudinally applied with overlap. • Inner sheath: Polyethylene. • Armour: Two helically applied steel tapes with a thickness of 0.5 mm each. • Outer sheath: UV resistant black polyethylene. • Sheath marks : The sheath shall be marked, at a regular intervals, with the following information o Name of manufacturer/ Year/ Length marks o Other type of marks according to the costumer All drawings, designs, specifications and particulars of weights, dimensions, etc. in this documentation are only indicative and must not be considered contractual.
