特种绕组线规范 第43部分:240级芳香聚酰亚胺薄膜绕包圆铜线

[中文适用范围]： IEC 317的本部分规定了240级带绕包圆形铜绕组线的要求。绝缘由一层或两层芳香族聚酰亚胺带绕包组成。 240级是耐热等级，要求温度指数至少为240，热冲击温度至少为260℃。注意 - 在某些国家/地区，例如加拿大、俄罗斯、美国，该产品被指定为 220 级。胶带的一侧或两侧涂有合适的粘合剂，例如氟化乙烯丙烯。缠绕后，将胶带热封以形成连续且粘附的护套。具体要求以合同为准。与温度指数相对应的摄氏度温度不一定是建议使用电线的温度，这将取决于许多因素，包括所涉及的设备的类型。本标准涵盖的标称导体直径范围为：1,600 mm 至 5,000 mm（含）。标称导体直径在表1中给出。当根据本标准引用绕组线时，应给出以下信息： ——引用IEC 60317-43； - 导体的直径； - 年级。示例：60317-43 IEC 2,000 mm A2 级 [外文原描述]： IEC 60317-43:1997 specifies requirements of tape wrapped round copper winding wire of class 240. The insulation consists of one or two wrappings of aromatic polyimide tape. Class 240 is a thermal class that requires a temperature index of at least 240, and a heat shock temperature of at least 260 °C. NOTE In some countries, e.g. Canada, Russia, USA, this product is assigned a class 220. The tape is coated on one or both sides with a suitable adhesive, for instance, fluorinated ethylene propylene. After wrapping, the tape is heat-sealed to form a continuous and adherent sheath. Specific requirements may be subject to contract. The temperature in degrees Celsius corresponding to the temperature index is not necessarily that at which the wire is recommended to be used and this will depend on many factors, including the types of equipment involved. The range of nominal conductor diameters covered by this standard is 1,600 mm up to and including 5,000 mm. The nominal conductor diameters are given in table 1. When reference is made to winding wire according to this standard, the following information should be given: – reference to IEC 60317-43; – diameter of the conductor; – grade.
