安全使用DJYPVP2x2x0.75計算機電纜的方法

    DJYPVP2x2x0.75計算機電纜適用(yong)(yong)于額定電(dian)(dian)(dian)(dian)(dian)壓500V及以下(xia)對(dui)(dui)于防(fang)干擾(rao)性(xing)(xing)要求(qiu)較(jiao)高的(de)電(dian)(dian)(dian)(dian)(dian)子計算機和(he)(he)自動化連接用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)纜。電(dian)(dian)(dian)(dian)(dian)纜地線芯絕(jue)緣采(cai)用(yong)(yong)具(ju)有(you)抗氧(yang)化性(xing)(xing)能(neng)的(de)K型B類低密度(du)(du)聚乙(yi)烯。聚乙(yi)烯的(de)絕(jue)緣電(dian)(dian)(dian)(dian)(dian)阻高，耐電(dian)(dian)(dian)(dian)(dian)壓好(hao)，介(jie)(jie)電(dian)(dian)(dian)(dian)(dian)系數(shu)小和(he)(he)介(jie)(jie)質損耗溫度(du)(du)和(he)(he)變頻率的(de)影響也小，不但能(neng)滿足(zu)傳輸(shu)性(xing)(xing)能(neng)的(de)要求(qiu)，而且能(neng)確(que)保(bao)電(dian)(dian)(dian)(dian)(dian)纜的(de)使用(yong)(yong)壽命(ming)。 為了(le)減(jian)少回路間的(de)相互串擾(rao)和(he)(he)外部(bu)干擾(rao)，電(dian)(dian)(dian)(dian)(dian)纜采(cai)用(yong)(yong)屏(ping)蔽(bi)(bi)結構。電(dian)(dian)(dian)(dian)(dian)纜的(de)屏(ping)蔽(bi)(bi)要求(qiu)是根據不同場合(he)分(fen)別采(cai)用(yong)(yong)：對(dui)(dui)絞(jiao)(jiao)組合(he)屏(ping)蔽(bi)(bi)、對(dui)(dui)絞(jiao)(jiao)組成電(dian)(dian)(dian)(dian)(dian)纜的(de)總屏(ping)蔽(bi)(bi)、對(dui)(dui)絞(jiao)(jiao)組合(he)屏(ping)蔽(bi)(bi)后總屏(ping)蔽(bi)(bi)等方(fang)法。 屏(ping)蔽(bi)(bi)材料有(you)圓銅線，銅帶、鋁帶/塑料復合(he)帶三種(zhong)。屏(ping)蔽(bi)(bi)對(dui)(dui)與屏(ping)蔽(bi)(bi)對(dui)(dui)具(ju)有(you)較(jiao)好(hao)的(de)絕(jue)緣性(xing)(xing)能(neng)，電(dian)(dian)(dian)(dian)(dian)纜在使用(yong)(yong)中若屏(ping)蔽(bi)(bi)對(dui)(dui)屏(ping)蔽(bi)(bi)對(dui)(dui)之(zhi)間出現電(dian)(dian)(dian)(dian)(dian)位差時(shi)，不會影響信號(hao)的(de)傳輸(shu)質量。

    安全使用DJYPVP2x2x0.75計算機電纜的方法：
     1.保證施工質量，特別是電纜頭的制作質量一定要嚴格符合規定要求。
     2.加強電纜運行監視，避免電纜過負荷運行。
     3.按期進行電纜測試，發現不正常時應及時處理。
     4.電纜溝要保持干燥，防止電纜受潮，造成絕緣下降，引起短路。
     5.定期清掃電纜上所積粉塵，防止所積粉塵自燃引起電纜著火。
     6.加(jia)強電(dian)纜回路開關及保護(hu)的定期(qi)校驗(yan)維護(hu)，保證其動(dong)作(zuo)可靠(kao)。
