为了永远与血泪交融,哀雾弥漫隔绝,我们工作的每一天都要从中吸取血淋淋的借鉴。许多年来,我们无数老前辈,老师傅们深以安全重任在心中,万众一心消灭违章,在风雨飘摇的日日夜夜里,构建安全金字塔,把生命的守护神请回到我们的身边。生命对于我们每一个人来说只有一次,并且我们生活得如此灿烂,我们对生命有着浓厚且深沉的热爱。安全就是生命,生命就是安全!为什么只有当我们侥幸走出事故的阴影;为什么只有当同事不幸在作业中致残;为什么只有惨不忍睹的事故发生在身边,我们才会惊恐、害怕、绝望和撕心裂肺的呼喊…..我们安全生产的神经才会再次绷紧?悔恨的泪水才会洒落胸前?为什么?为什么?难道这一桩桩血的教训还没有给我们足够的启示吗?我们为什么要次次痛定思过后才把心中安全的金字塔构建。

  我国国家标准GB12666.6(等同IEC331)将耐火试验分A、B两种级别,A级火焰温度950~1000℃,持续供火时间90min,B级火焰温度750~800℃,持续供火时间90min,整个试验期间,试样应承受产品规定的额定电压值。

BVR相比BV线来说要软、过流能力强、施工更方便,价格也要贵一些。由于BV线是单股线和同截面积BVR相比,它的铜丝要粗,当温度长期较高时不容易烧断;BVR线的铜丝比较细,温度较高时容易烧断其中一两根。只要电线中有一两根铜丝被烧断,那么烧断截面积减少,电阻更大,电线更容易被烧毁。在实际应用中,由于BVR线比较软,时间一长接头容易松动;而BV线相对来说就好很多,所以在家装中为了防止接头松动都要采取“挂锡”工艺。
