It was fortunate for me that I happened to become a denizen of that interesting old city during one of its better periods. Socially it was at high-water mark; the theatres were good and the French opera the better of all outside of Paris. In the winter it was the rendezvous for the well-to-do families of the whole far South. The rich cotton planters from Tennessee, Mississippi, and Alabama, and the sugar planters from along the “coast” came to this Southern metropolis, and brought with them their pretty daughters with their velvety voices, unaffected speech, garnished 93 with its tint of African accent, and their frank, disingenuous ways; and also came their sons, who were not so fascinating, but were good fellows at heart—the majority of them—and, as a rule, se for one weakness, they were all right. But they had the unpleasant habit of “drawing at sight,” and to the credit of their alertness, I am compelled to record that they were apt to see very quick.

专业生产研发各类煤矿用阻燃通信电缆、煤矿用阻燃电缆、煤矿用阻燃控制电缆，煤矿用阻燃通讯电缆、矿用电缆、矿用通信电缆、矿用电缆、矿用通讯电缆、，矿用控制电缆，矿用监控电缆、矿用监测电缆、矿用遥测电缆、控制电缆、计算机电缆、阻燃电缆、耐火电缆， 市内通信电缆、铁路电缆、通信设备电源线等，

为了评定线缆的阻燃性能优劣，电工会分别制定了IEC60332-1、IEC60332-2和IEC60332-3三个。IEC60332-1和IEC60332-2分别用来评定单根线缆按倾斜和垂直布放时的阻燃能力（国内对应GB12666.3和GB12666.4）。IEC60332-3（国内对应GB12666.5-90）用来评定成束线缆垂直时的阻燃能力，相比之下成束线缆垂直时在阻燃能力的要求上要高得多。

阻燃电缆和耐火电缆的区别：一般人很容易混淆阻燃电缆和耐火电缆的概念，虽然阻燃电缆有许多较适用于化工企业的优点，如低卤、低烟 阻燃等，但在一般情况下，耐火电缆可以取代阻燃电缆，而阻燃电缆不能取代耐火电缆。

 ZR-CEFR/DA 2*2.5 船用电缆

矿用橡套电缆结构特点：一：导电线芯。柔软性要求以电钻电缆，采掘机电缆为高；导线结构采取如下措施：1，采用较软的细直径铜单线、以小节距束合、复绞。整根电缆的弯曲扭转性还受到绝缘、护套结构的影响，因此不能认为单丝越细，节距越小越好。2，采用同向束绞和复绞可提高柔软性。3，为了便于导线在绝缘层中的相对滑动和便于安装维修。电钻电缆和小截面的采掘机电缆导线单丝应镀锡，大截面采掘机电缆在导线外还用包纸带隔离绝缘。二：绝缘层要求有足够的电绝缘性能1，采用含胶量不低于百分之35的橡皮2，绝缘厚度比通用橡套电缆要厚3，采用电性好的橡皮，并采用好的挤橡工艺（如挤橡硫化连续生产线）

1、电缆绝缘主线芯之间及主线芯与地线之间的绝缘电阻,换算到+20℃时不低于100MΩ•km。

2、主线芯屏蔽层的过渡电阻换算到20℃时不高于3kΩ。

3、产品标准：MT818.5-1999。

4、MYP型电缆有3个带绝缘屏蔽的主线芯和一个包覆半导电橡皮层的地线组成，围绕半导电橡皮层垫芯绞合成缆。外面挤包黑色氯化聚乙烯橡皮护套或黑色氯丁橡皮护套。

5、导电线芯：采用软铜线，其性能符合 GB/T3956-1997。

6、绝缘：采用GB7594.2-1987中XJ-00A型橡皮。
