CCTSST-FR0.3 n×4×1.4
Application
CCTSST-FR0.3 n×4×1.4 cables are used as railway cables and can be installed directly into the ground or in
ducts.
Reference Standards
RENFE E.T. 03.365.051.6
Construction
Conductors: Soft annealed solid copper, 1.4 mm nominal diameter.
Insulation: PE insulation.
Cabling Element: Four insulated conductors are twisted together to form a quad.
Stranding: Quads are helically stranded in concentric layers.
Core Wrapping: Two or more layers of plastic tape(s) with overlapping.
Screen: Copper tapes with overlap (protection against interference).
Inner Sheath: LSZH sheath, coloured green.
Armour: Two layers steel tape (0.8mm thick).
Outer Sheath: LSZH sheath, coloured green.
