本產品適用于(yu)(yu)額定電(dian)(dian)壓500V及以下對于(yu)(yu)防干擾性要求較(jiao)高的(de)電(dian)(dian)子計(ji)(ji)算(suan)機(ji)和自(zi)動化(hua)連接用電(dian)(dian)纜(lan)(lan)(lan)。電(dian)(dian)纜(lan)(lan)(lan)地線芯絕(jue)緣(yuan)(yuan)采用具有抗氧化(hua)性能的(de)K型B類低密度聚乙烯。敷(fu)設(she)時環境溫(wen)度不(bu)(bu)低于(yu)(yu):固定敷(fu)設(she)-40℃,非固定敷(fu)設(she)-15℃。最小彎曲(qu)半徑(jing)(jing)：無鎧(kai)(kai)裝層(ceng)應不(bu)(bu)小于(yu)(yu)電(dian)(dian)纜(lan)(lan)(lan)外徑(jing)(jing)的(de)6倍，帶鎧(kai)(kai)裝層(ceng)的(de)電(dian)(dian)纜(lan)(lan)(lan)應不(bu)(bu)小于(yu)(yu)電(dian)(dian)纜(lan)(lan)(lan)外徑(jing)(jing)計(ji)(ji)算(suan)機(ji)電(dian)(dian)纜(lan)(lan)(lan)計(ji)(ji)算(suan)機(ji)電(dian)(dian)纜(lan)(lan)(lan)的(de)12倍。在20℃時用直流(liu)500V電(dian)(dian)壓試驗穩定充(chong)電(dian)(dian)1min后絕(jue)緣(yuan)(yuan)電(dian)(dian)阻應不(bu)(bu)小于(yu)(yu)2500MΩ·Km。

各對(dui)絞屏(ping)蔽(bi)之(zhi)(zhi)間(jian)以(yi)及(ji)對(dui)絞屏(ping)蔽(bi)與(yu)總屏(ping)蔽(bi)之(zhi)(zhi)間(jian)應不斷(duan)路(lu)。電(dian)(dian)(dian)纜(lan)的(de)線(xian)芯(xin)和線(xian)芯(xin)之(zhi)(zhi)間(jian)以(yi)及(ji)屏(ping)蔽(bi)之(zhi)(zhi)間(jian)應經受50HZ，交流2000V電(dian)(dian)(dian)壓試驗5min不擊穿。聚(ju)乙烯的(de)絕緣電(dian)(dian)(dian)阻(zu)高，耐電(dian)(dian)(dian)壓好，介電(dian)(dian)(dian)系數小(xiao)和介質損(sun)耗溫度和變頻率的(de)影(ying)響也(ye)小(xiao)，不但能滿足傳輸性能的(de)要(yao)求，而且能確保(bao)電(dian)(dian)(dian)纜(lan)的(de)使(shi)用(yong)壽命。

為了減少回路間的(de)相互串擾和(he)外部干擾，電(dian)(dian)纜采用(yong)屏(ping)(ping)(ping)蔽(bi)(bi)結構。電(dian)(dian)纜的(de)屏(ping)(ping)(ping)蔽(bi)(bi)要求是根(gen)據不(bu)(bu)同(tong)場合(he)分別采用(yong)：對(dui)(dui)絞組合(he)屏(ping)(ping)(ping)蔽(bi)(bi)、對(dui)(dui)絞組成電(dian)(dian)纜的(de)總(zong)屏(ping)(ping)(ping)蔽(bi)(bi)、對(dui)(dui)絞組合(he)屏(ping)(ping)(ping)蔽(bi)(bi)后總(zong)屏(ping)(ping)(ping)蔽(bi)(bi)等(deng)方法(fa)。屏(ping)(ping)(ping)蔽(bi)(bi)材料有圓(yuan)銅線(xian)，銅帶(dai)(dai)、鋁帶(dai)(dai)/塑料復(fu)合(he)帶(dai)(dai)三種(zhong)。屏(ping)(ping)(ping)蔽(bi)(bi)對(dui)(dui)與屏(ping)(ping)(ping)蔽(bi)(bi)對(dui)(dui)具有較(jiao)好的(de)絕緣性能，電(dian)(dian)纜在(zai)使用(yong)中若屏(ping)(ping)(ping)蔽(bi)(bi)對(dui)(dui)屏(ping)(ping)(ping)蔽(bi)(bi)對(dui)(dui)之間出現電(dian)(dian)位差時，不(bu)(bu)會影(ying)響信號的(de)傳輸質量。
