漆包圆绕组线.第22部分:180级聚酰胺复合聚酯或聚酯亚胺漆包圆铜线

[中文适用范围]： GB/T 6109的本部分规定了双漆层的180级漆包铜圆线的要求。 底漆层以聚酯或聚酯亚胺树脂为基， 如果能保留原树脂的化学特性并且满足该漆包线规定的所有要求， 则该树脂可以改性。 面漆层是以聚酰胺树脂为基。 注：改性树脂是一种经过化学变化的， 或者含有一种或多种添加剂以提高其某种性能或使用特性的树脂。 180级表示热级， 它要求最小温度指数为180， 热冲击温度至少为220℃。 对应于温度指数的摄氏温度并不就是推荐的漆包线使用温度， 因为这取决于包括所用设备类型在内的很多因素。 本部分规定的导体标称直径范围为： － 1级：0.050mm及以上3.150mm及以下； － 2级：0.050mm及以上5.000mm及以下； － 3级：0.250mm及以上1.600mm及以下； 导体标称直径按GB/T 6109.1-2008中第4章的规定。 [外文原描述]： 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.
