Electrical Cables - Business Recycling

Electrical cables are generally composed of a metal conductor inner housed in a plastic insulation. Recycling cables aids in the resource recovery of both the metal and the plastic outer for reuse. The most common metals used are copper and aluminium. When recycled these metals don’t degrade which means they can be recycled indefinitely.

Cable Recovery - History of the Atlantic Cable

2020-12-29  To aid in the maintenance of cables, and to avoid conflicts with the routes of existing cables as new ones are laid, the route of each cable is surveyed, and the track of the cable as laid is precisely charted. Compare these two surveys from 1890 and 1973, which show how improvements in have aided this task. In 1973 the best satellite navigation equipment allowed an accuracy of about ± ¼ mile; now GPS satellite systems make the surveying and charting of new cables

2009-9-15  Beryllium-copper, C17200, is an example of a precipitation-hardening, sometimes called age-hardening, alloy. C17200 contains two percent of alloying agents, typically 1.8 percent beryllium and 0.2 percent cobalt. Copper cannot hold 1.8 percent of beryllium in solution at room temperature. This fact is the key to precipitation hardening.
