This standard applies to the emission (radiated and conducted) of radiofrequency disturbances from: all lighting equipment with a primary function of generating and/or distributing light intended for illumination purposes, and intended either for connection to the low voltage electricity supply or for battery operation; the lighting part of multi-function equipment where one of the primary functions of this is illumination; - independent auxiliaries exclusively for use with lighting equipment; UV and IR radiation equipment; neon advertising signs; street/flood lighting intended for outdoor use; - transport lighting (installed in buses and trains). Excluded from the scope of this standard are: lighting equipment operating in the ISM frequency bands (as defined in Resolution 63 (1979) of the ITU Radio Regulation); lighting equipment for aircraft and airports; - . apparatus for which the electromagnetic compatibility requirements in the radio- frequency range are explicitly formulated in other IEC or CISPR standards. NOTE Examples are: - built-in lighting devices in other equipment, for example scale illumination or neon devices; - photocopiers; - slide projectors; - lighting equipment for road vehicles. The frequency range covered is 9 kHz to 400 GHz. Multi-function equipment which is subjected simultaneously to different clauses of this standard and/or other standards shall meet the provisions of each clause/standard with the relevant functions in operation. The limits in this standard have been determined on a probabilistic basis to keep the suppression of disturbances within economically reasonable limits while still achieving an adequate level of radio protection and electromagnetic compatibility. In exceptional cases, additional provisions may be required.
第一种是内外层为聚乙烯,第二种是内层为交联聚乙烯,外层为聚乙烯,第三种是内外层均为交联聚乙烯,中部层均为铝层。第一种一般用于冷水管道系统,后两种一般用于热水管。 4铜管又称紫铜管。有色金属管的一种,是压制的和拉制的无缝管。优点:铜管质地坚硬,不易腐蚀,且耐高温、耐高压,是最好的给水管材。缺点:价格高。 ...

(1)绝缘交联度;铝合金电缆优于铜缆的其中一点是合格的铝合金电缆全部采用交联聚乙烯绝缘,电缆工作温度为90度。正因为采用交联聚乙烯绝缘,就存在交联度问题,正规的专业铝合金电缆生产厂家都应有专门的绝缘交联室来保障绝缘的完全交联。 (2)绞合导体;在导体的绞合技术和导体绞合生产装备上,目前国内铝合金电缆企业和铜缆企业的绞合导体装备基本类同。...
