Anotation

Specifies the requirements of enamelled round copper winding wire of class 180 with a dual coating. The underlying coating is based on polyester or polyesterimide resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. The superimposed coating is based on polyamide resin. Class 180 is a thermal class that requires a minimum temperature index of 180 and a heat shock temperature of at least 200°C. The temperature in degrees Celsius corresponding to the temperature index is not necessarily that at which it is recommended that the wire be operated and this will depend on many factors, including the type of equipment involved. The range of nominal conductor diameters covered by this standard is as follows: - grade 1: 0,050 mm up to and including 3,150 mm; - grade 2: 0,050 mm up to and including 5,000 mm; - grade 3: 0,250 mm up to and including 1,600 mm. The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-1. The main changes with respect to the previous edition are listed below: - new requirements for appearance, Subclause 3.2, added; - breakdown voltage values, former Table 3, replaced with a reference to IEC 60317-0-1; - new pin hole test, Clause 23, added. Specifie les exigences concernant les fils de bobinage de section circulaire en cuivre emaille de classe 180 avec un double revetement. La sous-couche est a base de resine polyester ou polyesterimide, qui peut etre modifiee pour autant que cette resine conserve lidentite chimique de la resine initiale et reponde a toutes les exigences du fil. La surcouche est a base de resine polyamide. Une classe 180 est une classe thermique qui exige un indice de temperature minimal de 180 et une temperature de choc thermique dau moins 200 °C. La temperature en degres Celsius correspondant a lindice de temperature nest pas necessairement celle a laquelle il est recommande dutiliser le fil; cela dependra de beaucoup de facteurs, y compris du type dequipement considere. La gamme des diametres nominaux des conducteurs couverte par la presente norme est la suivante: - grade 1: 0,050 mm jusque et y compris 3,150 mm; - grade 2: 0,050 mm jusque et y compris 5,000 mm; - grade 3: 0,250 mm jusque et y compris 1,600 mm. Les diametres nominaux des conducteurs sont specifies dans lArticle 4 de la CEI 60317-0-1. Les modifications principales par rapport a ledition precedente sont les suivantes: - nouvelles exigences pour les aspects, Paragraphe 3.2, ajoute; - valeurs de tension de claquage, ancien Tableau 3, remplacees par une reference a la CEI 60317-0-1; - nouvel essai de detection des micro-fissures en immersion, Article 23, ajoute.
