Railway Cables

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).
