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.

專業(yè)生產(chǎn)研發(fā)各類煤礦用阻燃通信電纜、煤礦用阻燃電纜、煤礦用阻燃控制電纜，煤礦用阻燃通訊電纜、礦用電纜、礦用通信電纜、礦用電纜、礦用通訊電纜、，礦用控制電纜，礦用監(jiān)控電纜、礦用監(jiān)測電纜、礦用遙測電纜、控制電纜、計算機電纜、阻燃電纜、耐火電纜， 市內(nèi)通信電纜、鐵路電纜、通信設(shè)備電源線等，

為了評定線纜的阻燃性能優(yōu)劣，電工會分別制定了IEC60332-1、IEC60332-2和IEC60332-3三個。IEC60332-1和IEC60332-2分別用來評定單根線纜按傾斜和垂直布放時的阻燃能力（國內(nèi)對應(yīng)GB12666.3和GB12666.4）。IEC60332-3（國內(nèi)對應(yīng)GB12666.5-90）用來評定成束線纜垂直時的阻燃能力，相比之下成束線纜垂直時在阻燃能力的要求上要高得多。

阻燃電纜和耐火電纜的區(qū)別：一般人很容易混淆阻燃電纜和耐火電纜的概念，雖然阻燃電纜有許多較適用于化工企業(yè)的優(yōu)點，如低鹵、低煙 阻燃等，但在一般情況下，耐火電纜可以取代阻燃電纜，而阻燃電纜不能取代耐火電纜。

 ZR-CEFR/DA 2*2.5 船用電纜

礦用橡套電纜結(jié)構(gòu)特點：一：導(dǎo)電線芯。柔軟性要求以電鉆電纜，采掘機電纜為高；導(dǎo)線結(jié)構(gòu)采取如下措施：1，采用較軟的細(xì)直徑銅單線、以小節(jié)距束合、復(fù)絞。整根電纜的彎曲扭轉(zhuǎn)性還受到絕緣、護套結(jié)構(gòu)的影響，因此不能認(rèn)為單絲越細(xì)，節(jié)距越小越好。2，采用同向束絞和復(fù)絞可提高柔軟性。3，為了便于導(dǎo)線在絕緣層中的相對滑動和便于安裝維修。電鉆電纜和小截面的采掘機電纜導(dǎo)線單絲應(yīng)鍍錫，大截面采掘機電纜在導(dǎo)線外還用包紙帶隔離絕緣。二：絕緣層要求有足夠的電絕緣性能1，采用含膠量不低于百分之35的橡皮2，絕緣厚度比通用橡套電纜要厚3，采用電性好的橡皮，并采用好的擠橡工藝（如擠橡硫化連續(xù)生產(chǎn)線）

1、電纜絕緣主線芯之間及主線芯與地線之間的絕緣電阻,換算到+20℃時不低于100MΩ•km。
