控制(zhi)電纜(lan)安裝布線的(de)注意事項
1.電(dian)纜(lan)只(zhi)在(zai)(zai)不直接暴露在(zai)(zai)陽光照射或(huo)超高(gao)(gao)溫下，標(biao)準局域(yu)網電(dian)纜(lan)就可以應用，建議使用管(guan)(guan)道(dao)(dao)。 紫外(wai)(wai)線(xian)(UV)--不要(yao)將無(wu)紫外(wai)(wai)線(xian)防護的(de)(de)電(dian)纜(lan)應用于陽光的(de)(de)直射環境(jing)內(nei)。2.外(wai)(wai)墻上。避免陽光直接照射墻面(mian)及人(ren)為(wei)損(sun)壞。熱度--電(dian)纜(lan)在(zai)(zai)金(jin)屬管(guan)(guan)道(dao)(dao)或(huo)線(xian)槽內(nei)的(de)(de)溫度很高(gao)(gao)，許多聚(ju)合材料在(zai)(zai)這種(zhong)溫度下會(hui)降低使用壽命。3.管(guan)(guan)道(dao)(dao)里(塑料或(huo)金(jin)屬的(de)(de))。如在(zai)(zai)管(guan)(guan)道(dao)(dao)里，注意塑料管(guan)(guan)道(dao)(dao)的(de)(de)損(sun)壞及金(jin)屬管(guan)(guan)道(dao)(dao)的(de)(de)導熱。機械(xie)損(sun)壞(修(xiu)復費用)--光纜(lan)的(de)(de)修(xiu)復是十分昂(ang)貴
