SW-CLT Switching Centre Cables

Application

TheSW-CLT Switching Centre 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).
