Tesar, cast resin transformers for the tallest skyscrapers in the world
The present environmental situation is obliging modern installation to use products will low environmental impact. This is one of the reasons that has led to the widespread use of cast resin transformers, instead of those in dielectric liquid: without oil and, therefore, without the risk of leaks and environmental pollution. Moreover, cast resin transformers from Tesar feature high self-extinguishing, and are therefore conform to the strictest norms, in particular IEC 60076-11, which Tesar conformed to six years ago. And this is the reason that is convincing the most important worldwide consultants to install resin machines inside the tallest buildings, but above all to prefer F1 certified transformers. In this way, the installation of a product with a low flammable level and low emission of toxic gases and dense fumes, minimizing risks both for firefighters and for inhabitants, is guaranteed. This type of machinery is therefore to be preferred in ‘sensitive’ installations such as the tallest building in the world (Bury Khalifa in Dubai, 828 metres), the Canary Wharf in London, the Emirates Tower in Dubai. And, above all, it is thanks to these new norms that today, especially in high-rise buildings, transformers are installed at intermediate floors, near the charge, with the consequent reduction in the use of substations and savings in energy also caused by the reduced use of loss of current in the same cables. Energy savings that automatically mean fewer CO2 emissions.
Favier, ecology as a goal
Sigi, leader in Italy in the production of insulating tubes for thermal and dielectric insulation was purchased by French company Favier Tpl six years ago. And these six years have been dedicated to the research and development of new products with higher performance and environmentally friendly materials. Favier Tpl, a leader in Europe, has decided, through research and development, to increase its market share of developing countries while remaining alert to new markets or new applications that may require the use of insulators.
"Ecology is too important a subject not to invest in research and resources - says General Director Mathieu Favier. All Favier products are already solvent free and the Sigi product range will soon be 100% solvent free too (now most of Sigi tubes are produced with water-based paints). Our goal is to make clear to customers the importance of using materials without solvents, which will surely be eliminated or greatly reduced in the near future, so we hope that our partners and customers will take this issue seriously with regards to ecology, as well to be at the forefront in the choice of materials that will soon be used".
Abb completes acquisition of Baldor Electric Company
Abb, the leading power and automation technology group, has completed the acquisition of Baldor Electric Companyof Baldor Electric Company, a North American leader in industrial motors. The transaction was valued at $4.2 billion, including $1.1 billion of net debt.
The acquisition of Baldor advances Abb’s strategy to become a leader in the North American industrial motors business and a global leader for movement and control in industrial applications.

These businesses will be headquartered in Fort Smith, Arkansas, Usa, which is Baldor’s current headquarters location. Baldor’s former Chairman and Ceo, John McFarland, will remain with the Company to support a successful integration.
“Today marks a significant step forward in Abb’s strategy to become the global leader in the industrial motion market,” said Joe Hogan, Abb’s Ceo. “Baldor has built an excellent reputation through its focus on innovation, quality and service, and we look forward to working together with the Baldor team to deliver solutions that support our customers and deliver on this excellent combination”.
Ulrich Spiesshofer, Abb Executive Committee member responsible for the Discrete Automation and Motion division of which Baldor is now a part, said, “From this point forward we will be working to unleash the full potential of this strategic combination. Together we have an excellent opportunity to serve our customers even better and to build a stronger business than it would be possible to do as separate companies. I am confident that the knowledge, experience and determination of people in both organizations will result in a strong, cohesive team focused on delivering exceptional products and services to our customers in North America while opening new growth opportunities around the world”.
“Abb is world renowned for the quality of its products, the skill of its people and the vision of its leaders. We are joining an absolutely top-tier organization with the reach and resources to significantly extend the Baldor brand. As part of Abb’s global
Baldor has a bright future ahead,” said Ron Tucker.

"Cold plasma" applications in the electric motors sector
"Cold plasma" is the name given to the new process for the pre-treatment of plastic, vitreous and electronic surfaces, prior to their encapsulation or sealing/gluing with silicon, polyurethane and epoxy resins, which enhance their adhesion. Developed by Bartec Dispensing Technology, a worldwide leader in the production of machinery for the dispensing of resins, which use both dynamic and static mixing technology. "Cold plasma" treatment is so called because, even if it has high superficial energy, it does not overheat the treated surfaces, thus enabling to process any type of material. The machine is also equipped with a process monitoring system that makes it reliable, repeatable, and easily integrated into existing processes.
In the electric motor sector, it will certainly have an interesting application as far as all service applications are concerned. For example, in the case of circuit integration, control devices (inverters) on board the transport unit, in particular in the sealing of boxes and in gluing of parts subject to considerable stress. An application that is becoming more and more frequent is the plasma treatment of the surfaces of magnets before proceeding with the gluing of the same onto the rotor, or the treatment of the surfaces of electric cables prior to encapsulation in resin or gluing, especially with regards to IP67 or Atex motors.
Omem, the nano-crystalline materials revolution
"It is the most important technical breakthrough in the last 20 years in the sector of energy transmission and distribution. The introduction of traditional-structure, nickel-based, nano-crystalline silicon-steel is a real revolution, which will lead to developments never before seen." This is the claim of Omem, an Italian company based in Brianza, to the north of Milan, which manufactures and exports all over the world its wound magnetic cores for transformers, also used for electric motors. According to Omem, the crystalline structure of nano-crystalline silicon-steel brings new prospects to the sector because it reduces the dispersion of energy during transformation and enables to produce smaller transformers with improved performance. A further benefit is the decrease in the use of isolation materials, along with a consequent reduction in environmental impact and costs. Therefore, in the next few years, development of this highly innovative material able to provide numerous advantages will continue.

Marty: new three axes vacuum chamber
Marty will soon begin the marketing of its new vacuum chamber with three interpolated axis. The prototype of this machine, which was presented at WEM Expo 2010, has undergone strict tests from November 2010 until March this year.
The new vacuum chamber is entirely made of anodized aluminium and the movement of its three interpolated axes X-Y-Z are guaranteed by precision brushless motors.
The vacuum chamber is combined with Marty series 8 dosing machines, designed for the continuous vacuum degassing and the dosing of numerous two components systems (epoxy resins, polyurethane resins, silicon resins, etc.).
The innovative degassing system of the series 8 plants will guarantee a dehumidified mixture without air bubbles, and a clean and automatic loading system directly from commercial containers, as well as precise and constant management of the temperature of the two components and vacuum levels of vacuum degassing.
The electric-electronic part of the vacuum chamber is incorporated in the electric cabinet of the dosing machine; the software has also been modified: the new software now allows to create up to 9,999 dosing programmes, with data regarding volume and speed, as well as the vacuum levels in the chamber and the movements of the three motorized axes.
These plants also have an important new application: a bar-code reader, to call up the dosing programme relative to the items to be processed and the memorization of the important data for the creation of the records of the items; ultrasounds sensor for the reading of the resin height inside the items in phase of dosing, to guarantee a perfect resin level.
