不注意(yi)电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)的(de)热(re)稳定(ding)(ding)(ding)会由(you)于绝缘材料的(de)变质(zhi)而造成电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)绝缘的(de)长久性破(po)(po)坏(huai)(huai)，从而可能伴生(sheng)(sheng)烟气和可燃(ran)气体。如果有(you)(you)足(zu)够的(de)热(re)量，这(zhei)些气体将(jiang)点燃(ran)起(qi)火，酿成严(yan)重的(de)火灾。即使(shi)程度(du)不那么严(yan)重，也(ye)可能使(shi)电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)的(de)绝缘或(huo)护(hu)套膨胀(zhang)，产生(sheng)(sheng)空隙，导致(zhi)有(you)(you)可能发生(sheng)(sheng)故障。对高压电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)，这(zhei)一点格外严(yan)重。除了热(re)应(ying)(ying)力(li)外，热(re)膨胀(zhang)还会在电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)中产生(sheng)(sheng)机械应(ying)(ying)力(li)。由(you)于急剧(ju)地(di)加(jia)热(re)，这(zhei)些应(ying)(ying)力(li)可能引(yin)(yin)起(qi)不希望有(you)(you)的(de)电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)移动(dong)。不过，新式电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)加(jia)强了捆绑和护(hu)套，xz地(di)降低(di)了这(zhei)种(zhong)应(ying)(ying)力(li)的(de)影(ying)响。在预(yu)定(ding)(ding)(ding)的(de)温度(du)范围(wei)内选择和使(shi)用电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)时，一般情况下不需要注意(yi)其机械特(te)性，除非电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)很旧或(huo)是(shi)铅包电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)。在发生(sheng)(sheng)短路或(huo)大的(de)冲击(ji)电(dian)(dian)(dian)(dian)流时，单芯电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)将(jiang)承(cheng)受各电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)之间的(de)互相排斥力(li)或(huo)吸(xi)引(yin)(yin)力(li)。为了防(fang)止由(you)于这(zhei)种(zhong)移动(dong)而引(yin)(yin)起(qi)电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)的(de)破(po)(po)坏(huai)(huai)，应(ying)(ying)将(jiang)敷设(she)在电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)支架或(huo)电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)桥架上的(de)电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)固定(ding)(ding)(ding)起(qi)来(lai)。YJLHV电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)厂家(jia)就找易(yi)缆(lan)(lan)(lan)通网络科技成都有(you)(you)限公司(si)。FS-YJFE电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)批发
