Cooperation in CTC expertise

Continuous transposed conductors (CTC) require sophisticated knowledge for the implementation of production. To this end, Pourtier – Gauder Group and Proteco have signed a contractual agreement joining their specific expertise in this area to offer a high quality integrated solution. Both companies have a strong back- ground in the power field. Pourtier has manufactured a comprehensive range of rotating machines dedicated to LV and EHV cables for 150 years; Proteco has produced equipment for the production of high power transformer conductors since 1993. This new alliance offers a complete planetary assembly line with Pourtier planetary strander type DRG560 (cage available from 24 up to 96 bobbins with reel dimensions 500, 560, 630 as option) and Proteco transposing head type TH5 (transposing frequency up to 250tpm). It is possible to upgrade the strander with more bays. Peripheral equipment, such as payoffs, taping heads, caterpillars and take-ups, is also available from Pourtier.

High-precision C, L & tan δ measuring bridge

The dielectric-loss analyzing system 2840 from Haefely is designed for measurement of very low dielectric losses and impedances (dissipation factor and power factor) of high-voltage apparatus. The instrument works on the principle of a combined bridge-vector-meter and is capable of analysing capacitive and inductive loads – especially shunt reactors – with accuracy (capacitance 0.02%, tan δ 1x10-5) and stability.

The graphical user interface of the instrument is highly intuitive, focused on convenience with built-in useful programs, and uses a large colour touch screen as the input device. While the manual mode provides quick measurements, the automatic test mode supports complete automated test sequences. Advanced software functionalities such as insulation temperature correction, programmable test sequences with pass/fail limits or graphical visualisation of measured data, make this instrument a powerful tool for analysis of high-voltage equipment. The instrument incorporates standard interfaces (such as USB) that enable easy exchange of measurement results and related settings for further analysis or reporting.
