SW-CLT Switching Centre 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).
