This is the General Pure Cable in UL for the UL1581. The experiment
required several samples to be laid on a vertical 8 foot high
bracket and 20 minutes with the specified 20KW ribbon spray lamp
(70,000 BTU/Hr). Qualified for flame not to spread to the upper end
of the cable and self-extinguishing. UL1581 is similar to iec
60332-3c except that the number of cable roots is different. There
is no smoke concentration specification for commercial grade
cables, which is generally only used for horizontal running of the
same floor, but not for vertical wiring of the floor.

今天我们在厂区换灯的时候看到一个同事打下空气开关后因为懒得拆线就用尖嘴直接把电缆剪断,你们认为这样剪电线是否正确。好像这样剪并没有错,空气开关都已经打下来了,平常很多人也都是这样剪,实际上这样剪线是比较危险的。有次我也在换一盏室外功率为55W的彩灯,因为原来的线是在灯壳里面接的,手上也有电笔但验不了电,除非把灯壳拆开。想想反正空气开关也打下了应该不会有电了,嫌麻烦就直接用尖嘴钳把电缆剪断,那一剪可使我终生难忘啊?直接听到一声爆炸声,眼前就像在漆黑的夜晚忽然打雷一样两眼看到一道白光。
