W tej dziedzinie certyfikat UL jest jednym z najbardziej presti\u017cowych znak\u00f3w zgodno\u015bci produktu i uznawanym na ca\u0142ym \u015bwiecie znakiem bezpiecze\u0144stwa, wydawanym przez Underwriters Laboratories\u00ae.

Je\u015bli chodzi o w\u0142a\u015bciwo\u015bci termiczne materia\u0142u, karta UL zawiera kilka wskaz\u00f3wek:<\/p>

  • Odporno\u015b\u0107 na p\u0142omie\u0144 - UL94, testowana zgodnie z norm\u0105 europejsk\u0105 IEC 60695-11-10;<\/li>

    Idealny izolator elektryczny to przede wszystkim taki, kt\u00f3ry spe\u0142nia specyfikacje.\u00a0<\/p>

    Punkt dotycz\u0105cy 4 kluczowych kryteri\u00f3w wyboru izolatora elektrycznego.<\/p>

    1. W\u0142a\u015bciwo\u015bci dielektryczne<\/strong><\/h3>

    Materia\u0142y izolacyjne musz\u0105 oczywi\u015bcie posiada\u0107 w\u0142a\u015bciwo\u015bci dielektryczne umo\u017cliwiaj\u0105ce skuteczn\u0105 ochron\u0119 sprz\u0119tu. Jednak w niekt\u00f3rych przypadkach konieczne jest, aby wybrana izolacja elektryczna by\u0142a w stanie wytrzyma\u0107 wysokie temperatury. W zwi\u0105zku z tym niekoniecznie nale\u017cy d\u0105\u017cy\u0107 do uzyskania najlepszej wydajno\u015bci pod wzgl\u0119dem dielektrycznym i konieczne b\u0119dzie znalezienie kompromis\u00f3w, w szczeg\u00f3lno\u015bci pod wzgl\u0119dem wytrzyma\u0142o\u015bci mechanicznej. Dowiedz si\u0119 wi\u0119cej o pogorszeniu w\u0142a\u015bciwo\u015bci dielektrycznych izolator\u00f3w.<\/p>

    2. Temperatura u\u017cytkowania<\/strong><\/h3>

    Wyb\u00f3r izolacji jest \u015bci\u015ble zwi\u0105zany z warunkami termicznymi, jakim b\u0119dzie ona poddawana w trakcie eksploatacji. Rzeczywi\u015bcie, izolator mo\u017ce z jednej strony ulec degradacji pod wp\u0142ywem ciep\u0142a, a z drugiej strony jego wytrzyma\u0142o\u015b\u0107 dielektryczna zmienia si\u0119 wraz z temperatur\u0105. Przy wyborze izolacji nale\u017cy zatem zwr\u00f3ci\u0107 uwag\u0119 na klas\u0119 termiczn\u0105 sprz\u0119tu.<\/p>

    3. Kryterium ekonomiczne<\/strong><\/h3>

    Aspekt ekonomiczny jest wa\u017cnym kryterium, kt\u00f3re nale\u017cy wzi\u0105\u0107 pod uwag\u0119 przy wyborze izolatora, poniewa\u017c r\u00f3\u017cnice w kosztach mog\u0105 by\u0107 du\u017ce mi\u0119dzy dwoma materia\u0142ami. Koszt wysokowydajnego izolatora mo\u017ce zwi\u0119kszy\u0107 niezawodno\u015b\u0107 izolowanego sprz\u0119tu, a tym samym umo\u017cliwi\u0107 osi\u0105gni\u0119cie znacznych korzy\u015bci na innych stacjach tworz\u0105cych system.<\/p>

    4. Wyb\u00f3r uznanych materia\u0142\u00f3w<\/strong><\/h3>

    Nale\u017cy pami\u0119ta\u0107, \u017ce Nie wszystkie materia\u0142y s\u0105 sobie r\u00f3wne<\/strong> nawet je\u015bli ich sk\u0142ad chemiczny jest a priori identyczny.

    \u00a0<\/p>

    1. Poliestry<\/span><\/strong><\/h3>

    Same poliestry b\u0119d\u0105 w stanie zaakceptowa\u0107 prac\u0119 w temperaturach do 160\u00b0C lub nawet wi\u0119cej, w zale\u017cno\u015bci od czasu ekspozycji. Normy m\u00f3wi\u0105 o 130\u00b0C dla IEC i 105\u00b0C dla UL. Na przyk\u0142ad poliester PET dzia\u0142a dobrze do 105\u00b0C, a PEN mo\u017ce by\u0107 nadal u\u017cywany w temperaturze 160\u00b0C.<\/span><\/p>

    \u00a0<\/p>

    2. Polietylen<\/span><\/strong><\/h3>

    Polietylen jest dobrym izolatorem, ale nie mo\u017ce by\u0107 u\u017cywany w temperaturach powy\u017cej 60\u00b0C\/RTI UL lub 130\u00b0C\/IEC.<\/span><\/p>

    \u00a0<\/p>

    3. Poliimid<\/span><\/strong><\/h3>

    Poliimid jest najbardziej wydajnym polimerem, je\u015bli chodzi o dobr\u0105 izolacj\u0119 elektryczn\u0105 w wysokiej temperaturze, poniewa\u017c jest w stanie wytrzyma\u0107 ponad 400\u00b0C przez kilka godzin. Najbardziej znan\u0105 mark\u0105 poliimidu jest Kapton, dost\u0119pny w postaci klej\u00f3w lub rolek folii.<\/span><\/p>

    \u00a0<\/p>

    4. Sztywne lub elastyczne materia\u0142y<\/span><\/strong><\/h3>

    Aby poprawi\u0107 wydajno\u015b\u0107 termiczn\u0105, mo\u017cliwe jest r\u00f3wnie\u017c po\u0142\u0105czenie zalet kilku materia\u0142\u00f3w. W ten spos\u00f3b Nokamex Duplex sk\u0142ada si\u0119 z po\u0142\u0105czenia dw\u00f3ch materia\u0142\u00f3w:<\/span><\/p>

    • Folia poliimidowa Kapton, zapewniaj\u0105ca odporno\u015b\u0107 na temperatur\u0119 i izolacj\u0119;<\/span><\/li>
    • Papier aramidowy Nomex zapewniaj\u0105cy wytrzyma\u0142o\u015b\u0107 mechaniczn\u0105;<\/span><\/li><\/ul>

      \u00a0<\/p>

      Uzyskany materia\u0142 jest zatem doskona\u0142ym izolatorem, nadaj\u0105cym si\u0119 do u\u017cytku w wysokiej temperaturze i o wysokiej odporno\u015bci mechanicznej.<\/span><\/p>
