前言这是涂层电气套管的协调CSA集团和UL标准。这是CSA-C22的第三版。2第198.3号和UL 1441第五版。此版本为CSA-C22。2第198.3号取代1995年和2005年出版的前一版。本版UL 1441取代2018年11月27日发布的前一版。本标准的制定符合加拿大标准委员会对加拿大国家标准的要求。CSA集团已将其作为加拿大国家标准发布。范围1。1本标准的要求适用于A级和B级丙烯酸聚合物涂层、硅酮聚合物涂层或乙烯基聚合物涂层电气套管，该套管由玻璃制成的紧密编织织物组成（材料和额定值见表1），拟用于根据CSA C22的规定安装和使用的设备。 1，加拿大电气规范第一部分（CE规范第1部分），或ANSI/NFPA 70，国家电气规范（NEC）。可接受在高于1.2所示温度下使用的产品或不同的聚合物涂层或纤维，前提是（A）其符合本标准中的性能测试；（b）按照UL 746B或CAN/CSA-C22进行长期热老化试验。2 No.0.17，将介电强度作为主要性能，将可燃性作为次要性能。1.2这些要求适用于标准温度指数分类为105、130、155、180、200、220、，和240°C.1.3这些要求适用于与干燥或潮湿位置的电气设备和器具的内部接线相关的涂层电气套管，在干燥或潮湿位置不可能使用标准绝缘导体，例如器具- 接线材料，专门用于此目的。涂层电气套管用于绝缘一个或多个未绝缘或部分绝缘的导体、母线、元件引线或电气元件组件。涂层电气套管可用于不承受反复弯曲或严重机械应力的设备中。1.4这些要求适用于偶尔或间歇接触油的耐油涂层电气套管。1.5这些要求不适用于未涂覆或未涂覆的织物套管，由于套管织物编织结构中固有的开口，通常认为其不可用于鞋底（功能）绝缘。 1.6这些要求不适用于用钢筋挤压的管道、挤压的电气管道或仅用于机械保护的管道，因为它们包含在其他要求中。1.7当涂层电气套管用作105°C（A类）以上绝缘系统中的接头绝缘时，这些要求不适用于涂层电气套管。

PrefaceThis is the harmonized CSA Group and UL standard for Coated Electrical Sleeving. It is the third edition of CSA-C22.2 No. 198.3 and the fifth edition of UL 1441. This edition of CSA-C22.2 No. 198.3 supersedes the previous edition (s) published in 1995 and 2005. This edition of UL 1441 supersedes the previous edition published on November 27, 2018. This standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope1.1 The requirements of this Standard apply to Grades A and B acrylic-polymer-coated, siliconepolymer-coated, or vinyl-polymer-coated electrical sleeving that consists of closely woven fabric made from glass (see Table 1 for materials and ratings) and intended for use in equipment designed to be installed and used in accordance with the rules of CSA C22.1, Canadian Electrical Code, Part I, (CE Code, Part 1), or ANSI/NFPA 70, National Electrical Code (NEC). A product for use at temperatures greater than indicated in 1.2 or a different polymer coating or fiber may be acceptable provided that (a) it meets the performance tests in this Standard; and (b) long-term heat-aging tests are conducted as covered in UL 746B or CAN/CSA-C22.2 No. 0.17, using dielectric strength as a primary property and flammability as a secondary property.1.2 These requirements apply to coated electrical sleeving having a standard temperature index classification of 105, 130, 155, 180, 200, 220, and 240 °C.1.3 These requirements apply to coated electrical sleeving intended for use in connection with the internal wiring of electrical devices and appliances located in dry or damp locations where it is not feasible to employ a standard insulated conductor, such as appliance-wiring material, specifically intended for the purpose. Coated electrical sleeving is intended for insulating one or more uninsulated or partially insulated conductors, bus bars, component leads, or assemblies of electrical components. Coated electrical sleeving may be employed in equipment where it is not subjected to repeated flexing or severe mechanical stress.1.4 These requirements apply to oil-resistant coated electrical sleeving intended for occasional or intermittent contact with oil.1.5 These requirements do not apply to unimpregnated or uncoated fabric sleeving, which is generally not considered acceptable for sole (functional) insulation because of the openings inherent in the weave construction of the sleeving fabric.1.6 These requirements do not apply to tubing extruded with reinforcement, extruded electrical tubing, or tubing intended only for mechanical protection, since they are covered by other requirements.1.7 These requirements do not apply to coated electrical sleeving when it is employed as splice insulation in an insulation system above 105 °C (Class A) operation.
