标准摘要
[中文适用范围]： 适用范围：IEC 60800:2021+AMD1:2026 适用于低温应用场合（如舒适供暖及防冻）的电阻加热电缆，并规定了相关要求。此类加热电缆及加热电缆组件可采用工厂预制或现场组装形式，且须严格按照制造商说明书进行装配。本文件不适用于额定电压等于或低于 50 V 的裸导体及防护导体。典型应用包括但不限于：敷设于表面内部或下方的表面加热；直接加热及蓄热供暖；屋顶、檐沟、管道等部位的融雪与防冻。工业与商业用的电伴热系统另有 IEC 62395 系列规定；应用于爆炸性环境者则另有 IEC/IEEE 60079-30 系列规定；矿物绝缘加热电缆亦不在此文件范围内。凡护套温度超过 100°C 的应用，亦属本文件适用范围之外。 [外文原描述]： IEC 60800:2021+AMD1:2026 CSV is applicable to, and specifies requirements for resistive heating cables for low temperature applications such as comfort heating and the prevention of ice formation. These heating cables and heating cable sets can comprise either factory assembled or field (work-site) assembled units, and are heating cables assembled in accordance with manufacturer’s instructions. Bare conductors and protected conductors to be supplied at voltages equal to, or less than, 50 V are excluded from the scope of this document. Typical applications include, but are not limited to: - surface heating installed in or under surfaces; - direct and storage heating; - snow melting and frost protection of roofs, gutters, pipes, etc. Electrical resistance trace heating systems for industrial and commercial applications are specified in the IEC 62395 series [1] and for explosive atmospheres applications in the IEC/IEEE 60079-30 series [2], as are mineral insulated heating cables. Applications in which the sheath temperature exceeds 100 °C are outside the scope of this document.
英文名称Heating cables with a rated voltage up to and including 300/500 V for comfort heating and prevention of ice formation
