柔性绝缘套管 - 第3部分:各种类型套管规格145至147:挤出Ptfe套管

[中文适用范围]： IEC 60684-3 的下列文件给出了三种挤出聚四氟乙烯（PTFE）非热缩套管的规范。此类套管通常提供内径高达 8.53 毫米，壁厚范围在 0.15 毫米至 0.51 毫米之间。本规范涵盖三种壁厚等级："薄壁"、"正常壁厚"和"厚壁"，具体取决于公称内径，并对应不同的击穿电压要求。产品性能经验表明，PTFE 套管适用于在最高 250°C 温度下运行的系统。这些套管通常提供以下不透明颜色：黑色、棕色、红色、橙色、黄色、绿色、蓝色、紫色、灰色、白色、粉红色和绿松石色。也可提供无色产品。除本规范列出的尺寸和颜色外，其他尺寸和颜色可作为特殊项目提供。如果这些项目满足表 1 和表 2 中列出的其他特性要求，则应视为符合本规范。 These sheets of IEC 60684-3 give the requirements for three types of non-heat-shrinkable sleeving, extruded from PTFE. Sleeving of this type is normally available with internal diameters up to 8,53 mm and in a range of wall thicknesses between 0,15 mm and 0,51 mm. This specification covers three levels of wall thickness: "thin wall", "standard wall" and "thick wall" related to nominal internal diameter and with corresponding differences in requirements for breakdown voltage. Experience of product performance indicates that PTFE sleeving may be suitable for inclusion in systems for operation at temperatures up to 250°C. These sleeves are normally available in the following opaque colours: black, brown, red, orange, yellow, green, blue, violet, grey, white, pink and turquoise. It is also available as noncoloured. Sizes or colours other than those specifically listed in this standard may be available as custom items. These items shall be considered to comply with this standard if they comply with the other property requirements listed in tables 1 and 2.
