Nexans, a leading cable manufacturer, has announced plans to develop an underground Extra High Voltage (EHV) cable manufacturing plant in the US, which is expected to be commissioned in the summer of 2013. The company also intends to extend its submarine High Voltage (HV) activities. Investment is expected to amount to US$80M. Nexans hopes that the facilities will allow it to meet the growing demand from the EHV and HV cable market in the US.

Kuwait - LS Cable & System wins $110M order LS Cable & System announced that it had secured a 400kV extra-high voltage cable project valued at $110 million (about KRW130 billion) from the Ministry of Electricity and Water of Kuwait. LS Cable & System said it will supply and install 400kV extra-high voltage conductor with insulated cables and connectors on a turnkey basis. LS Cable & System said that unlike ordinary extra-high voltage cable using pure copper for the conductor, the conductor with insulated cables to be installed will be a high-tech cable in which the strands of wire comprising the conductors are coated with enamel to reduce transmission resistance. This raises transmission capacity by more than 20%. When this type of conductor with insulated cable is used, the overall weight and thickness of the cable can be reduced, as much as the transmission resistance falls, greatly reducing the cost of cable manufacturing and power grid implementation.

"The Kazakhstani project is designed to resolve power deficiencies caused by expansive urban and industrial development in Almaty, the capital city. LS Cable & System will provide products, such as 127km of 220kV level extra high-voltage transmission cables and joints, and technical consultation until August next year. In addition, 140km of OPGW (optical ground wire, see glossary) and 1,100km of 220kV level gap conductors (see glossary) will be supplied together with installation support by year end to San Lorenzo and Guarambare for national backbone power and communication network implementation in Paraguay.

This technology seems to me to be much more beneficial on a local scale, what if every home had its own battery, then home power generation becomes economically more viable for everyone. If you could show that a system like this could pay for itself in say 5 years then every home would want one. Plus for this to be implemented on a large scale requires massive investment that could be decades away. Share the technology and lets get it in homes by next year. Great ted talk. Jon Senior 0 Reply 1 hour ago: I agree 100%. Localised energy production would also make energy consumers more conscious of their consumption and encourage efforts to reduce it. We can invent and invent all we want, but the fast solution to allowing renewable energies to take centre stage is to reduce the base energy draw. With lower baseline consumption, smaller "always on" generators are required to keep the grid operational. Town and house-l

Sumitomo Electric Industries Ltd (SEI) said it plans to increase the production of wire harnesses for automobiles by around 10% in the fiscal year ending March 2013. The company said this is to keep pace with the growing demand from emerging countries. In order to make this possible the company is investing an extra JPY16.5B (US$201M) to reach a record JPY77B (US$979M) for the year to add extra facilities and assembly lines at the company's existing plants located worldwide.

LS Cable may see a 5% y-o-y fall in its copper consumption in the current year. This will be the second consecutive year that copper consumption dropped, as the company already experienced a 5% y-o-y plunge in 2008 to 270,000t. Copper accounts for about 30% of the company's production costs. LS Cable has announced that it is focusing on higher value added products such as underground and extra high-voltage cables in developing regions including the Middle East, China and other Asian countries.

"These extra-powerful laser pulses produced microgrooves, on top of which densely populated, lumpy nanostructures were formed. The structures essentially alter the optical and wetting properties of the surfaces of the three metals, turning the normally shiny surfaces velvet black (very optically absorptive) and also making them water repellent. "

"To prevent the theft of these cables, Network Rail have specified Panduit super heavy duty stainless steel banding to wrap around the cables and securely strap them to the cable trough. This measure will make the cables more difficult to access and extract therefore deterring thieves owing to the considerable extra time and effort involved and the added risk of detection, apprehension and arrest. The frequency of Panduit cable locking needs to be balanced with cost and the need to maximise the quantity of locked cables as quickly as possible. As a result of this, the below table sets out how often Panduit stainless steel rail cable bands should be used."

"in addition Nexans will present its latest Extra High Voltage partial undergrounding cable systems. This is helping to move overhead lines underground. "

China's government recently announced its 12th five-year plan for its energy industry, and it said it will build a 200,000km extra high voltage (EHV) power grid with capacity higher than 330 KV by 2015. Also announced, the government has set its compound annual growth rate for power installed capacity at 9.0% from 2011-2015, lower than the 13.3% from 2005-2010, demonstrating its intention to slow down investment in the power industry. It expects its installed capacity will be expanded to 1.49 billion KW, up 9.0% from 970 million KW at the end of 2010.

Nexans has announced that construction of its first high voltage power cable manufacturing plant in North America has begun. The plant is sited in Berkeley County, Charleston, S Carolina. Frederic Michelland, Nexans Senior Corporate Executive Vice President said, "The establishment of our first high voltage cable manufacturing plant in North America is a key strategic development for Nexans. It will enable us to capitalize on the ever growing demand for high quality high voltage cables designed and manufactured to meet the specific needs of the major power transmission infrastructure projects planned in North America and worldwide in the coming years." The plant is to begin operations in 2014 and has an initial investment of US$85M. The first phase of the facility will focus on the manufacture of underground power cables up to extra high voltage (EHV) levels of 500 kV and the company hopes it will reinforce Nexans' current product range in North America, adding to the existing medium voltage, low voltage, overhead transmission, industrial, building wire, electrical wire and LAN portfolios.
