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. H Folke Sandelin AB – Sweden Fax : +46 141 203639

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.
