Lorsque l\u2019on parle de torons en cuivre de classe 2<\/strong>, la classe faire r\u00e9f\u00e9rence \u00e0 diverses caract\u00e9ristiques des fils. Les c\u00e2bles \u00e9lectriques sont, en effet, class\u00e9s en fonction de leur flexibilit\u00e9<\/strong>, un terme qui d\u00e9signe non seulement la simple facult\u00e9 de se courber, mais aussi d’autres aspects li\u00e9s \u00e0 la structure du c\u00e2ble lui-m\u00eame.<\/p>\n

<\/strong>Cette flexibilit\u00e9,<\/strong> d\u00e9pend du diam\u00e8tre de chaque fil \u00e0 l’int\u00e9rieur du c\u00e2ble. En raison de son importance, ce param\u00e8tre a \u00e9t\u00e9 normalis\u00e9 dans le tableau IEC 60228,<\/strong> la norme globale de la Commission \u00e9lectrotechnique internationale sur les conducteurs de c\u00e2bles isol\u00e9s.<\/p>\n

On peut ainsi choisir des c\u00e2bles de classes diff\u00e9rentes<\/strong> en fonction des applications et des propri\u00e9t\u00e9s que les fils doivent garantir, en tenant compte des informations contenues dans le tableau.<\/p>\n<\/div><\/div><\/div><\/div>

Les classes de flexibilit\u00e9 des c\u00e2bles \u00e9lectriques<\/h2>\n<\/div><\/div>
<\/div>

Les classes de flexibilit\u00e9 des c\u00e2bles \u00e9lectriques<\/strong> sont au nombre de quatre :<\/p>\n

    \n
  • Classe 1 : conducteurs id\u00e9aux pour les installations permanentes ;<\/li>\n
  • Classe 2 : conducteurs destin\u00e9s \u00e0 une installation fixe ;<\/li>\n
  • Classe 5 : conducteurs flexibles, pr\u00e9f\u00e9rables en cas de vibration, de courbure ou de petit rayons de mouvement ;<\/li>\n
  • Classe 6 : conducteurs tr\u00e8s flexibles.<\/li>\n<\/ul>\n

    Le tableau IEC 60228<\/strong> tient \u00e9galement compte de deux autres param\u00e8tres importants : la taille et la r\u00e9sistance<\/strong>. Du point de vue dimensionnel, on \u00e9value la surface de la section transversale nominale pour les conducteurs standards. Ainsi, dans le cas de c\u00e2bles de classe 1 et 2<\/strong> par exemple, on consid\u00e8re le nombre minimum de filaments n\u00e9cessaires pour obtenir un conducteur d’une taille donn\u00e9e, tandis que pour les classes 5 et 6 <\/strong>on tient compte du diam\u00e8tre maximal de toute les parties du conducteur.<\/p>\n

    La r\u00e9sistance<\/strong>, quant \u00e0 elle, se mesure en ohm\/km et s’\u00e9value en consid\u00e9rant la valeur maximale admissible pour chaque taille, classe et type de conducteur. . Le but de cette classification est d’obtenir une d\u00e9finition standard des diff\u00e9rents conducteurs<\/strong>, car le cuivre peut avoir des valeurs de r\u00e9sistance diff\u00e9rentes, m\u00eame \u00e0 taille \u00e9gale. C’est pourquoi, si l’on prend en compte la taille nominale d\u00e9termin\u00e9 par la r\u00e9sistance, on parvient \u00e0 normaliser les param\u00e8tres et \u00e0 obtenir une comparaison plus pertinente.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/section>

    Torons en cuivre de classe 2<\/h2>\n<\/div><\/div>
    <\/div>

    Les Torons en cuivre de classe 2 pr\u00e9sentent des caract\u00e9ristiques techniques tr\u00e8s pr\u00e9cises<\/strong> : il suffit en effet d’un simple coup d’\u0153il au tableau IEC 60228 pour remarquer les principales diff\u00e9rences avec les autres conducteurs.<\/p>\n

    Tandis que les c\u00e2bles de classe 1, par exemple, peuvent contenir un seul fil, le toron en cuivre de classe 2<\/strong> est constitu\u00e9 d’au moins 7 fils simples de diam\u00e8tre inf\u00e9rieur \u00e0 celui de la classe pr\u00e9c\u00e9dente. Malgr\u00e9 la diff\u00e9rence moyenne \u00e9vidente sur le plan des diam\u00e8tres, un c\u00e2ble de classe 2 est peu flexible<\/strong>, donc non adapt\u00e9 aux applications impliquant des courbures ou des petits rayons de mouvement.<\/p>\n

    Les conducteurs de classe 2<\/strong>, sont en revanche plus r\u00e9sistants face \u00e0 des conditions atmosph\u00e9riques corrosives et \u00e0 des temp\u00e9ratures \u00e9lev\u00e9es ou dans les applications de soudure. De fait, ils doivent toujours \u00eatre envelopp\u00e9s d’une gaine<\/strong>, ce qui non seulement am\u00e9liore leur isolation \u00e9lectrique mais les rend aussi plus solides m\u00e9caniquement.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/section>\n","protected":false},"excerpt":{"rendered":"Corde in rame di classe 2 Lorsque l\u2019on parle de torons en cuivre de classe 2, la classe faire r\u00e9f\u00e9rence \u00e0 diverses caract\u00e9ristiques des fils.
