特种绕组线规范.第3部分:聚酯漆包圆铜线,155级

[中文适用范围]： GB/T 6109的本部分规定了以聚酯树脂为基的单一漆层155级漆包铜圆线的要求。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。 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。 155级表示特级， 它要求最小温度指数为155， 热冲击温度至少为175℃. 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：0.020 mm 及以上3.150 mm 及以下； －2级：0.020 mm 及以上5.000 mm 及以下. 导体标称直径按GB/T 6109.1-2008中的第4章的规定。 [外文原描述]： Specifies the requirements of enamelled round copper winding wire of class 155 with a sole coating based on polyester resin, which may be modified provided it retains the chemical identity of the original resin and meets all specified wire requirements. Class 155 is a thermal class that requires a minimum temperature index of 155 and a heat shock temperature of at least 175 °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: 0,020 mm up to and including 3,150 mm; - grade 2: 0,020 mm up to and including 5,000 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; - the constant K, applied in calculating the number of revolutions for the peel test, Clause 8, increased from 130 mm to 150 mm; - the test temperature for the cut-through test, Clause 10, increased from 240 °C to 270 °C; - new pin hole test, Clause 23, added. This publication is to be read in conjunction with IEC 60317-0-1:2008 .
