标准摘要
[中文适用范围]: 本国际标准规定了三种类型的绝缘套管的要求,这些套管由聚对苯二甲酸乙二醇酯纱线编织或针织而成,并涂有连续的丙烯酸基涂层,根据击穿电压的不同分为:高击穿电压(第 420 页)、中等击穿电压(第 421 页)和低击穿电压(第 422 页)。该套管通常内径在 0.5 mm 至 25 mm 之间,通常提供以下颜色:黑色、黄色、棕色、蓝色和红色。除本标准中明确列出的尺寸和颜色外,其他尺寸和颜色也可作为定制产品提供。如果这些产品符合表 2 和表 4 中列出的性能要求,则视为符合本标准。产品性能经验表明,这些 sheets 中规定的套管类型适用于 130 °C 下的运行,在某些应用中可适用于高达 155 °C 的温度。 [外文原描述]: Gives the requirements for three types of sleeving constructed from polyethylene terephthalate yarns using either braided or knitted construction, with a continuous acrylic based coating and differentiated by their breakdown voltage: high breakdown voltage (sheet 420), medium breakdown voltage (sheet 421) and low breakdown voltage (sheet 422). Experience of product performance indicates that sleeving of the types specified in these sheets may be suitable for operation at 130 °C or in some applications at temperatures up to 155 °C.
