Von Roll has the right solution to improve the quality and cost-effectiveness of the high-voltage insulation you need for your applications. With Samicapor, Von Roll has designed a range of outstanding VPI mica tapes that fulfill the requirements of main wall and end-winding insulation, namely High dielectric strengthCorona discharge resistanceFast and easy impregnationResin retention without drainingSmooth application without creasingBoth manual and fast-running machine applicationFull compatibility with predefined resin systemsApplicable for flat coil technology

Electrical stress control measures are an essential component of any high-voltage machine. Von Roll has developed conductive and semi-conductive tapes under the trade names CoronaShield C and CoronaShield SC. These tapes can be applied as: External corona protection - within the slotEnd corona protection - outside the slot

By developing and producing state-of-the-art Cablosam tapes for the manufacture of fire-resistant cables, Von Roll is making an important contribution to disaster prevention. Our Cablosam mica products have a worldwide reputation and have been specifically developed for use with our customers taping technologies, while complying with the most stringent international standards. Cablosam tapes are also free from halogens and do not create hazardous fumes. Von Roll offers tape widths from 4mm upwards delivered as pads or cross-wound spools. The tape on a cross-wound spool may be up to 20 km in lenght, depending on the width and dimensions of the spool. Von Roll also offers wires fully taped with Cablosam tapes according to our customer wishes.

Assuring optimum quality of main wall insulation requires careful selection of micaceous tape and detailed attention to the way the tape is applied and processed. We offer a complete range of resin-rich (RR) main wall insulation tapes and systems under the name Samicatherm for both conventional and hydrostatic pressing and Filosam and Samicaflex for the overhang areas. The advantages of these tapes are that they:Have high dielectric strengthResist corona dischargeCan be applied smoothly without creasingCan be applied by fast-running machines or manuallyHave short cutting times
