Nexans cable could reduce copper theft from railways

Indeed, according to UK rail infrastructure operator Network Rail it is a crime that costs the economy £19m each year.

In one of the latest efforts to combat this growing threat, European cable specialist Nexans has developed a number of cabling solutions that could make copper cable less attractive to thieves, harder to steal, and easier to trace in the event that it is stolen.

While most railway cables — in particular earthing cables — are constructed entirely from copper, the copper core conductor in Nexan’s new cable is protected by an outer layer of alternating copper and galvanised steel wires that is difficult to cut, and almost impossible to recycle.

According to Nexans, the cables, which are currently being piloted by a number of European rail network operators, are fully compatible with existing copper cables, and use the same tools and cable lugs and with excellent bending properties and form stability.

In a related development, the company has also developed a cable that incorporates a coded fire-resistant copper tape that is intertwined with the cable cores and outer cable.
