| Nexans, France, as a leader of High Voltage Cables and Accessories, recently presented two of its new High Voltage accessories at CIGRE 2004.
New High Voltage accessories : Design and advantages
Nexans has extended its manufacturing programme to a dry type GIS Sealing end type DTF for the voltage levels of 123kV, 145kV And 170kV and for the connection of synthetic insulated cables (XLPE) to gas insulated switchgear (GIS). The concept allows to close the GIS before introduction of the power cable : GIS manufacturers can then perform tests on GIS before the installation of the power transmission line. With an adaptor, this sealing end fits onto installations according to IEC 60859 part 1 standard.
The fluid free design is another advantage of this sealing end and makes the termination maintenance free and environmentally friendly.
Nexans also presented the premoulded cold-shrink joint type CMP for High Voltage cables with synthetic insulation 72.5 kV. This product has been completely developed by Nexans. The joint is made of a premoulded elastomeric body with embedded geometrical field control. This accessory presents key advantages for installers. Actually, during the installation, the joint body can be easily positioned on the prepared cable insulation, by hand and without any special tool or source of heating. Moreover, the outer joint protection can be adapted to the client�s requirements.
The new products presented by Nexans during the CIGRE underline the dynamism of the Group in Research & Development. In 2003, Nexans invested more than 47 million euros in R&D; and employed 450 researchers, engineers and technicians. This strong involvement enhances the Group�s status as leader in cables and accessories (product quality, economic processes and respect for environment) and also prepares the markets of tomorrow.
