STANDARDS Construction: ADIF ET-03.365.051.6 DESCRIPTION AND APPLICATION Cables with 1 to 20 pairs individually shielded with an aluminium/polyester laminate. Conductors of 0.9 and 1.4 mm nominal diameter, PE insulation. Pairs are stranded into layers to form the core that is protected with an anti-inductive sheath with a reduction factor of 0,3. They are used as signalling cables in railways infrastructures where protection against power lines induction is required. For installation in ducts or directly buried. Protected against rodents. CONSTRUCTION • Conductors: Annealed copper, 0.9 and 1.4 mm of nominal diameter. • Insulation: Solid polyethylene. • Cabling elements: Shielded pairs with an aluminium/polyester tape. Continuity tinned wire under the tape. • Lay-up. Stranded in layers. Colour code as per ADIF ET-03.365.051.6. • Core wrapping: Dielectric tape longitudinally applied with overlap. • Cable screen. Corrugated copper tape longitudinally applied with overlap. • Inner sheath: Polyethylene. • Armour: Two 0.5 mm thick steel tapes helically applied. • Outer sheath: UV resistant black polyethylene. • Sheath marking: The outer sheath shall be marked in white ink, at 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.
