Elektrische Isolatoren sind in allen Industriezweigen unentbehrliche Elemente, da sie dazu dienen, Ger\u00e4te und Menschen zu sch\u00fctzen. Diese Isolatoren gibt es in Hunderten von Kombinationen aus Formen, Materialien und Baugruppen f\u00fcr oftmals sehr unterschiedliche Anwendungen. Hier ein kurzer \u00dcberblick \u00fcber diese Materialien.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Wie definiert man die elektrische Isolierf\u00e4higkeit eines Hochleistungsmaterials?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Die Funktion eines elektrisch isolierenden Materials besteht darin, den Stromfluss zwischen zwei leitenden Teilen zu verhindern, die einer elektrischen Potentialdifferenz ausgesetzt sind. Der elektrisch isolierende Charakter eines Materials wird durch seinen spezifischen Widerstand, eine physikalische Gr\u00f6\u00dfe, die durch den Buchstaben \u03c1 (\u03a9\u22c5m) symbolisiert wird, und durch seine dielektrische St\u00e4rke definiert, die der H\u00f6chstwert des elektrischen Feldes ist, das das Material vor einem Lichtbogen aushalten kann. Daher wird ein Material als isolierend bezeichnet, wenn sein spezifischer Widerstand gr\u00f6\u00dfer als 108 \u03a9\u22c5m ist.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Dielektrische Materialien sind in verschiedenen festen (Papier, Nonwovens, Folien) oder fl\u00fcssigen (Harze) Formen erh\u00e4ltlich.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Flexible Einlagen sind Einlagen mit einer Dicke von weniger als 1 Millimeter, die als Papier oder Fasern verkauft werden. Papiere wie Nomex\u00ae beispielsweise sind Meta-Aramide mit ausgezeichneter Temperaturstabilit\u00e4t (von -196\u00b0C bis +300\u00b0C). Es ist daher der ideale elektrische Insulator f\u00fcr viele Anwendungen: Transformatoren, Windturbinen, Hybridfahrzeuge usw. Andere, wie Nokamex, ein hochentwickeltes Laminat aus Kapton\u00ae-Polyimid und Nomex\u00ae-Aramidpapier, haben hervorragende thermische, elektrische und mechanische Eigenschaften.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Laminate sind eine Reihe von D\u00e4mmstoffen, die aus mehreren Materialschichten bestehen. Einlagen (Papier, Glasmatten, Glasgewebe, Glimmer) bilden die Basis der D\u00e4mmung, die vor der Polymerisation mit Phenol-, Polyester-, Epoxid- oder Silikonharz beschichtet wird. Sie sind in Tafelform erh\u00e4ltlich und reichen von wenigen Zehnteln eines Millimeters bis zu mehreren Dutzend Millimetern Dicke. So ist es m\u00f6glich, die Eigenschaften dieser Materialien zu kombinieren, um einen Insulator zu erhalten, der sowohl eine hohe thermische als auch eine hohe mechanische elektrische Leistung aufweist.<\/p>

Diese Insulatoren k\u00f6nnen in Motoren und Transformatoren, Generatoren, elektrischen Ger\u00e4ten... verwendet werden.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Folien sind isolierende Polymere mit einer Dicke von weniger als 0,5 mm, die in Rollenform erh\u00e4ltlich sind. Ihre Zusammensetzung variiert enorm und es gibt viele verschiedene Formulierungen mit ihren eigenen dielektrischen, thermischen und mechanischen Eigenschaften. So liegt die St\u00e4rke von Kapton\u00ae Typ Polyimiden in der Hitzebest\u00e4ndigkeit (bis zu 400\u00b0C als kurzzeitige W\u00e4rmespitze), w\u00e4hrend die anderen Eigenschaften sehr hoch bleiben, w\u00e4hrend Mylar\u00ae Typ Polyester zu den Insulatoren mit den h\u00f6chsten dielektrischen Werten geh\u00f6ren.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Die elektrische Isolierung kann auch durch Materialien in fl\u00fcssiger Form f\u00fcr ihre Verarbeitung bereitgestellt werden. Dies erm\u00f6glicht es, die fl\u00fcssige Isolierung dort unterzubringen, wo sie ben\u00f6tigt wird, bevor sie sp\u00e4ter ausgeh\u00e4rtet wird. Beispiele hierf\u00fcr sind Schutzlacke oder Kitte. Dar\u00fcber hinaus gibt es\u00a0fl\u00fcssige Impr\u00e4gnierharze vom Typ Epoxy oder Polyester<\/strong>\u00a0k\u00f6nnen den aus Fasern bestehenden Isolierungen hinzugef\u00fcgt werden, um steife Verbundmaterialien zu bilden.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Kleine Elektromotoren, die bei niedrigen Spannungen betrieben werden, wie z. B. Windschild-Wischerpumpenmotoren, k\u00f6nnen mit flexiblen Polyesterisolierfolien mit einer Dicke von etwa 100 Mikrometern isoliert werden, da sich die dielektrische Eigenschaft eines Insulators mit seiner Dicke \u00e4ndert. Flexible Insulatoren werden z. B. in Notchback- oder Zwischenphasenfunktionen verwendet.<\/p>

Auf der anderen Seite verwenden wir bei Turbogeneratoren oder Gasturbinentypen \u00fcblicherweise Slot-Closing-Materialien aus einem Hochleistungslaminat, das dicker und widerstandsf\u00e4higer ist und die Vorteile von zwei oder drei Materialien vereint.

In der Automobilindustrie werden elektrische Insulatoren u. a. auf Lichtmaschinen, Kabeln und der On-Board-Elektronik gefunden. Seit dem Aufkommen von Elektro- und Hybridautos hat sich dieser Bedarf nur noch erh\u00f6ht, weil die Batterien isoliert werden m\u00fcssen. Beispielsweise kann Formex\u00ae, ein Polypropylen in Folie oder Honeycomb-Paneele, verwendet werden. Bei diesen L\u00f6sungen kann es sich um w\u00e4rmeableitende Isoliermaterialien oder um Isoliermaterialien mit integrierten stromleitenden Eigenschaften handeln. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
