US - CommScope announces copper-alternative grounding wire to telecommunications industry - 0 views

  •  
    With the ongoing volatility of copper pricing creating a major concern for the telecommunications industry as telecoms operators traditionally use copper ground wire for network grounding and bonding, CommScope Inc. has developed a copper-alternative grounding wire designed to deter copper theft and lower maintenance costs for telecoms and data applications.

Donald Sadoway: The missing link to renewable energy | Video on TED.com - 0 views

  • Donald Sadoway: The missing link to renewable energy
  • What's the key to using alternative energy, like solar and wind? Storage -- so we can have power on tap even when the sun's not out and the wind's not blowing. In this accessible, inspiring talk, Donald Sadoway takes to the blackboard to show us the future of large-scale batteries that store renewable energy. As he says: "We need to think about the problem differently. We need to think big. We need to think cheap." Donald S

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

Practices for grounding and bonding of cable trays - 0 views

  • A bare copper equipment grounding conductor should not be placed in an aluminum cable tray due to the potential for electrolytic corrosion of the aluminum cable tray in a moist environment. For such installations, it is best to use an insulated conductor and to remove the insulation where bonding connections are made to the cable tray, raceways, equipment enclosures, etc. with tin or zinc plated connectors.

LS Cable & System vigorously develops new global markets - 0 views

  • 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.

Nexans' innovative overhead line technology helps Brazil solve electricity transmission... - 1 views

  • Resulting from a five-year development programme involving Nexans’ technology centres in France and Belgium, this innovative overhead line technology consists in a thermal resistant aluminium conductor wrapped around a composite carbon core. Compared with a traditional ACSR (Aluminium Conductor Steel Reinforced) which uses steel core, the composite carbon core of the same diameter is much lighter and 50 percent stronger. Most importantly, the carbon core’s coefficient of thermal expansion is roughly one tenth of that of steel, so it expands (and ‘sags’) much less when heated by the high current flowing in the conductor, enabling the vital safety clearances to be maintained between the conductor and the ground, even at high operating temperatures.

8 Main Disadvantages of HVDC Transmission - 0 views

  • Some of the above-listed disadvantages can be eliminated with the use of new technologies. In particular, disadvantages such as a complete power fault of the HVDC transmission system during short-circuits inthe AC power system and reactive power consumption can be eliminated completely, or mostly, with the use of turn-off thyristors.Several research centers are working on improving high-capacity turn-off thyristors and also on new types of converter devices for high-capacity HVDC transmission.Finally, there are several new techniques for the perfection of grounding devices, providing for decreased electro-corrosion impacts and the formation of so-called “metal return”, which precludes the working current from flowing through the ground. Other techniques aimed at perfecting HVDC technology are also being developed (Koshcheev 2001).

Spain to Cut Subsidies for Solar PV, not Solar Thermal - 0 views

  •  
    Last week the Spanish government announced plans to cut subsidies for solar photovoltaic (PV) power by about 75%. Although the nation expects to surpass its 2010 goal for installed solar by four fold, the down side is that generous subsidies for the industry have resulted in a ballooning tariff deficit for the country, which has risen to 4.85 billion euros, upfrom 745 million last year. Reuters reported that lending to the Spanish photovoltaic plants has risen to $3.59 billion in the year to day, up from $230.9 million euros last year and $192.44 million in 2006. As a result, the Spanish government will as the energy regulator to cap subsidies for new PV solar capacity at 300 megawatts (MW) per year--200 MW for rooftop systems and 100 MW for ground-mounted systems, which have been the highest growth area. CSP has been slower than PV technology in its emergence on the renewable energy scene, but expectations for the technology, which focuses the heat of the sun to produce steam to drive electricity producing turbines. Projects underway in the U.S. and Spain are expected to produce electricity that is cost-equivalent to electricity produced from burning coal or natural gas.

Shanghai copper down 2 pct, LME bounces - 0 views

  •  
    SINGAPORE, Sept 8 (Reuters) - Shanghai copper fell around 2 percent on Monday but it lagged behind a 4.5 percent slide in London prices after big jumps in inventories on Friday. But prices in London bounced on Monday, lifted by gains in other other commodity markets as the dollar lost ground against the euro after the U.S. government on Sunday seized control of mortgage finance companies Fannie Mae (nyse: FNM - news - people ) and Freddie Mac (nyse: FRE - news - people ), which own or guarantee half of all U.S. mortgages. LME copper rose $75 or 1.1 percent, to $6,975 at 0232 GMT, while Shanghai November copper dropped 1,030 yuan to 55,630 yuan ($8,130) and earlier touched a nine-month low.

Replacing pipes made of polybutylene - 0 views

  •  
    While older municipalities across Canada are busy replacing lead distribution water supply pipes that have been in the ground since the last century, others are having to replace pipes made of polybutylene (PB) that were installed as recently as 25 years ago. The polybutylene plastic service pipes were installed in the 1970s and 1980s to connect street mains to the home as a cheaper alternative to copper piping. However, the polybutylene pipes were subject to collapse, and over time have become brittle, are cracking and leaking water.

  •  
    CommScope, Inc. will supply the Bishop Hill Wind Farm in Henry County, Illinois with its GroundSmart(TM) Copper Clad Steel solution, an alternative to solid and stranded copper that is increasingly in demand by utilities for its cost-efficiency and anti-theft characteristics. CommScope will provide 1.7 million feet of GroundSmart copper clad steel grounding wire to the project this year--the largest GroundSmart application to date. The Bishop Hills Wind Farm will include approximately 130 wind turbines. Developers of Bishop Hill said that they see GroundSmart as a simple solution to reducing projects costs without compromising the system's integrity. Copper clad steel is specifically designed to disperse fault currents and lightning strikes at a lower total cost of ownership compared to pure copper.
