  • Researchers in the US have found yet another use for the "wonder material" graphene. Instead of exploiting the material's exceptional ability as an electrical conductor, the team has found a way to use graphene as an extremely thin "tunnel barrier" to conduction. The team says that this new application is particularly suited to developing spintronics – a relatively new technology that exploits the spin of an electron as well as its charge.

  • Lear's alternative wire technology reduces mass and copper dependence by replacing copper with copper clad steel (CCS). High tensile strength steel technology enables usage of smaller wire diameter while still meeting all vehicle conductivity requirements.

    Nexans, the large French wire and cable maker, announced that it has won a EUR80M (USD104.5M) contract to supply and install a 100km long high voltage direct current (HVDC) submarine cable in Newfoundland, Canada. The cable will form part of a new HVDC transmission link in Canada that stretches 1,100km. The submarine cable, which uses copper wire as its conductive core, will be manufactured in the company's NVC factory in Tokyo. The announcement is the second large submarine cable contract the company has won in the last 3 months, following the announcement that Nexans won the contract to supply and install a EUR300M (USD387.4M) submarine cable connecting Italy and Montenegro in late October 2012.

  • Our results show that, despite still needing efforts in terms of reproducibility of the assembly process and of AC loss reduction, this design is a promising and viable solution for high current-capacity cables made of coated conductors.

  • The focus is on high-voltage cables and cable harnesses for high power transmission. These special products are needed because, in cars and commercial vehicles with electric, hybrid or fuel cell drive, 12 volts no longer prevail on their own as they do in conventional vehicles with combustion engines. Instead, electrified powertrains involve voltages up to 1000, which require the cables and components to have special properties with respect to conductivity, mechanical flexibility, thermal capacity and safety

  • In conclusion, we have shown that a graphene coating transforms mechanically fragile nanotube networks into superelastic materials while maintaining the shape, strength, ultracompressibility, high porosity and conductivity of the networks.

    According to a survey conducted by the Copper & Brass Servicenter Association, a US-based trade group, US servicenter shipments of copper and brass products amounted to 22.7Mlbs (10,297t) in April, down by 7.0% m-o-m and down by 0.9% y-o-y. The m-o-m decline was largely attributed to weaker demand for 300-series brass rod and bar, as shipments declined by 9.9%, reaching 5.2Mlbs. Servicenters enjoyed a good Q1 as shipment levels rose to reach 72.7Mlbs (32,736t), up by 4.2% y-o-y, with the peak of the quarter occurring in March, just as it did in 2011. Over 50% of servicecenters surveyed believed that incoming orders will stay at the same level in June-August 2012 as they were in March-May 2012.
