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.

Cooperation in CTC expertise
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.
