The epidemic of telecom cable thefts has prompted a US company to develop a new design that drastically cuts down the copper content in a bid to deter metal thieves.
The GroundSmart Copper Clad Steel cable is probably the most radical solution yet devised to copper theft in that it removes almost all of the copper grounding (in the UK, earthing
) metal of the sort commonly used in networks to return current to earth for safety reasons.
Unlike conventional cables made from solid copper, the GroundSmart consists of a steel core around which is bonded a copper outer casing, forming an equally effective but far less valuable cable.
The end result, according to the company, is something that exploits the corrosion-resistance of copper with the conductive properties of steel — via http://redwolf.newsvine.com/_news/2012/01/17/10172062-copper-thieves-battled-with-new-anti-theft-telecom-cable
