Project Highlights CoC Cable Systems CoC Components Increased efficiency due to production optimisation In the course of 2009 all structural changes to the “Gussenstadt 2010” project were implemented at the Gussenstadt plant. The products are now manufactured in a flow-line production geared to the product lines and with a continuous manufacturing sequence. Optimised production and improved sequence structures, coupled with the focus on strategic main products, enable us to act even more forcefully on the market. New joint box housing in a unique design The tried-and-tested MSA joint box housing from PFISTERER IXOSIL AG now has an additionally improved successor. It guarantees watertightness by means of closure systems with double seals both for the crosswise divided housing and the closures for the intake piece. The housing is made from a robust thermoplastic and has great mechanical stability thanks to the 6-mm wall thickness. For more extensive requirements it is also possible to use fibre glass-reinforced material. It has also been made even easier to handle. The housing consists of two crosswise divided elements that are easy to lock securely by turning a bayonet closure one eighth of a revolution. Two large filler inlets make for easy filling with a suitable compound. The connections for docking on the shield are cast directly and, therefore, are mechanically extremely stable. Connections are, of course, also provided for partial discharge measurement, temperature sensors and possibly other monitoring systems. All tests in compliance with IEC 60840 and IEC 62067 have already been passed and the product has been marketed successfully since mid-2010. The additional orientation of customer relations in the case of OEM customers towards planning-centred cooperation over a period of more than twelve months and rolling coordination boosted both performance and market competitiveness. This was made possible by coordinating the planning more closely to suit the needs of the major customers, on the one hand, and the ability of sales and production personnel to consistently plan production capacities, on the other. Particularly in the field of components it is imperative to set competitive prices in a hard-fought market by reducing manufacturing costs and thereby benefiting from the reduction of fixed costs. The close coordination of large quantities for OEM customers, produced in large batches and with provisions in appropriate quantities, also created the latitude for smaller, but highly profitable small-series productions. Thus the response time for deliveries was reduced in both customer segments. 14
GROUP CoC Overhead Lines CoC Railway Catenary Systems High-speed project Ninghang 420-kV compact line in the Netherlands The Ninghang high-speed project in China with a sales volume of over EUR 1 million was very successful for PFISTERER in 2010. The Ninghang railway connection runs between the two capital cities of Nanjing, the capital of the province Jiangsu, and Hangzhou, the capital of the province Zhejiang. The railway line is approximately 136 km in length, from the district of Jiangning in Nanjing to Hangzhou via Changzhou, Wuxi and Yixing City in Wuxi. The high-speed railway is to be inaugurated in 2012 and will reduce the travelling time between Nanjing and Hangzhou to around one hour. In this project PFISTERER not only supplies the conventional products for railway catenary systems but also the To the south of Amsterdam the Dutch power supply company TenneT is extending its supply network to include a 420-kV compact line. The route through a densely populated area is highly demanding in terms of aesthetics and adherence to threshold values. entire aluminium fittings for the cantilevers: eyelet clamps, eyelet brackets, railway catenary fixtures, clevises, hook clamps and stable arm supports. The matter of quality is very important for these products, therefore in addition to breaking load tests, X-ray examinations were also carried out in order to test the structure of the aluminium fittings. It is important to maintain low threshold values for the magnetic field (0.4 mT) and noise emissions by corona discharge. The mechanical load types required new rod diameters and a high e-module for the rods in the silicone composite insulators. Since the qualification tests had already been passed in 2009, we were able to deliver the first insulator crossarms for this technically highly sophisticated project in 2010. 15
