Power cables
Lead sheathing of cables
H Folke Sandelin AB (HFSAB) is the official manufacturer of the continuous lead extruder and now introduces the latest horizontal
lead extruder to extrude the perfect moisture barrier onto medium to extra-high voltage cables.
The new equipment is floor standing,
requiring no special expensive founda-
tions, is said to be easy to maintain and
has fully automated controls with accurate
temperature control. Wall thickness can be
kept to a minimum, with corresponding
savings in lead.
Trained and experienced engineers support
the HFSAB horizontal lead extruder, either on
site or remotely, via the Internet.
Over 300 extruding machines have been
sold throughout the world, of which 20+
are the latest horizontal design, providing
continuous lead sheathing of cables. With
options in screw and die block sizes the
horizontal lead extruder covers a wide range
from 6mm to 225mm over lead.

Control in power cable production
Zumbach Electronic AG offers a wide range of dimensional measurement and quality monitoring systems for cable. The three-axis
ODAC® Trio gauge offers accurate detection of out-of-round condition, regardless of the orientation of the product ovality, in
combination with reliable and fast diameter measurement. The advantages include synchronised measurement axes on a single
plane, compact design, reliable detection of mean value regardless of the orientation of the product ovality, accurate computation of
circumference and cross section and integrated fault detection functions.
UMAC® represents a line of ultrasonic-based
systems for cable wall thickness measurement
and control. Each system consists of a highly
developed processor, interrogating up to eight
sensors at high speed. Wallmaster systems
process data from a wall thickness measuring
scanner and from several ODAC ® measuring
heads. Automatic control of wall thickness
and/or diameter is possible. Calibration can be
automated by means of the DIACAL function.
ODEX® utilises the latest technology in laser
optics and magnetic measurement. Fully digital
(DSP), extremely fast, stable and compact, ODEX®
provides accurate and reliable monitoring of
insulation diameter and conductor eccentricity/
concentricity during extrusion or other insulating
processes.
For data acquisition, processing and display,
Zumbach Electronic offers the USYS family
of multi-tasking controllers. All units provide
comprehensive on-line measurement, control
and quality monitoring. Diameter, ovality,
eccentricity and capacitance can be measured,
and additional sensors for faults, line speed or
events can be integrated.
