目前，随着科籍平的不断，阻燃问题已由过去的卤素阻燃化，进一步发展到低卤、无卤的阻燃化。公司在研制生产"通信电源用阻燃耐火软电缆"时，对电缆的绝缘、护套采用了低烟无卤、分解温度高、机械性能好的无卤聚合物材料，由于电缆不含卤化物和金属氧化物，在时不会产生有害气体和大量的烟雾，不存在会造成"二次灾害"的可能性，并且还具有良好的机械性能与电气性能，了电缆的使用要求，彻底改变了以往阻燃电缆的不足之处。

to England. This was merely a feeler and absurd, as Francis II. had nothing to gain by the Austrian match, but the Bishop maliciously told the Queen the joke, as he called it, whereupon she was very angry that her claim for Calais should be treated so lightly. She then told him that she saw now she must marry without delay, “although with the worst will in the world,” and tried again to lead him to believe that she was anxious to marry the Archduke, “but I fear,” said he, “that it is with the hope of gaining your Majesty’s favour in her cause, as she calls it, with the French.... Religious matters make me believe that in case she determines to marry, she will rather lay hands on any of these heretics than on the Archduke. I understand now that the Earl of Arran is excluded as being poor and of small advantage, and also because he is not considered personally agreeable. They all favour the Prince of Sweden as he is both heretical and rich, and especially Secretary Cecil,50 who would expect to remain at the head of affairs as at present.” Shortly afterwards, in September, 1560, Cecil took the Bishop aside and complained bitterly of Dudley, who he said was trying to turn him o

◎ 家居级- CMX级（垂直Vertial Wire Flame ）　这是 UL中家居级电缆（Restricted Cable），适用为UL1581，VW-1。实验规定试样保持垂直，用试验用的喷灯（30，000 TU/Hr）15秒钟，然后停止15秒钟，反复5次。合格为余火焰不可超过60秒钟，试样不可烧损25%以上，垫在底部的用棉不可被落下物引燃。UL1581-VW-1和IEC60332-1类似，只是的时间不同。这种等级也没有烟雾或毒性规范，仅用于敷设单条电缆的家庭或小型办公室中。这类电缆不应成捆敷设使用，必须套管。烟密度、卤素含量和毒性等级

变频器电缆性能设计与参照标准 ：1.8／3千伏及以下变频电机专用电缆电气性能均按GB／Tl2706，2002标准设计。6／10千伏变频电机专用电缆在满足GBT／l2706.2002标准外，增加了电容和电感等电性能要求。根据变频电机专用电缆的实际使用情况并参照GB／T12706.2002和ABB公司对电力传动电缆的技术条件，确定了电缆的电气性能参数。

he real facts of the case, and, if necessary, to offer Alen?on a refuge in England. But the Prince’s power, such as it was, had fled, and with it his spirit and his health. Biron kept command of the French garrisons in the conquered towns, whilst Alen?on wandered from Vilvorde to Dendremond and thence to Dunkirk, disavowed by his brother, and cursed even by his mother for his perversity.
