Lubrication from Lubrimetal The use of an advanced top performance drawing lubricant is key to the production of high quality finished wires. Lubrimetal manufactures an estab- lished range, including its well-known trademarks Fosfil ® and Steelfor ® phosphating agents, coatings and carriers. Steelfor ITS/5 is a new borax free salt coating for steel

Corrosion protection for overhead power conductors Corrosion of overhead power conductors, mainly ACSRs (alumi- nium conductors steel reinforced) is a major and costly problem and is especially severe in heavily polluted areas. Some 25 years ago, in response to this problem, Vapor-Tek Ltd developed a highly effective cor- rosion preventive grease to be applied to conductors during manufacture. The grease protects against both galvanic and crevice corrosion even in the presence of corrosive pollutants. Unlike some greases, which must be applied molten, Cablegard’s unusual rheo- logy enables the grease to be applied cold, straight from the drum as received. Cablegard is manufactured to the internationally recognised specifi- cations EN 50326:2002 and IEC 61934 and exceeds the corrosion requirements of the specifications. The performance of Cablegard was confirmed by SECRI (Shanghai Electricity Cable Research Institute), an important step towards its approval and use in the People’s Republic of China, where the corrosion problem is especially acute. SECRI was so impressed with the test results that Vapor-Tek was sponsored in the presentation of a technical paper at a seminar held in Chonging in November 2006. In receiving this invitation Vapor-Tek was uniquely privileged as the first non-Chinese organisation to attend the biennial SECRI symposium. The main topic at the 2006 seminar was “High voltage and ultra high voltage transmission projects over long distances” and delegates comprised scientists and engineers concerned with all aspects of electricity generation and distribution in China, including problems of corrosion.

Copper wire insulation with UV varnishes Years of experience in coating optical fibres with UV curable inks and resins have enabled Medek & Schoerner to develop a completely new line of products. For many years, copper wire has been insulated by applying layers of enamel (enamelled copper wire). Many coats of solvent-based varnishes are applied in several passes, and dried by evaporating the solvent. Medek & Schoerner’s new process involves replacing conventional solvent-based varnishes with varnishes cured by UV irradiation. This does not produce any solvent vapours, and the use of UV radiators reduces energy costs to far below the level previously required for thermal drying ovens at comparable levels of production. The elimination of solvent vapours, coupled with a considerable drop in energy costs, means the process has a reduced environmental impact. The UV curing station can be installed in existing wire enamelling lines and replace the conventional enamelling oven.
