SW-CLT Switching Centre Cables
Application
The cables are used as block cables for railway. The cables are suitable for connection between local switching
centre and the trackside and signalling equipments.
Standards
CFF: I-EB-SK 3001.82.1000
Construction
Conductors: Class 1 solid copper, 1.0/1.5/2.2mm nominal diameter.
Insulation: Solid polyethylene.
Cabling Element: Four conductors are twisted together to form a quad.
Inner Sheath: PE sheath.
Armour: Double galvanized steel tapes of 0.15mm.
Outer Sheath: PE/LSZH sheath.
Optional
Unarmoured Cable: The cables offered without galvanized steel tapes (SW).
Traction Armoured Cable: The cables offered with galvanized steel fl at wire armour with or without protection
sheath (SW-F/FT).
Halogenfree Sheathed Cable: The cables offered with LSZH sheath according to IEC 60332-3C (SW-CLN/FN).
