線鼻子之所以比直徑要大，主要是為了低壓無鹵電線廠家降(jiang)低(di)連(lian)接處(chu)的(de)(de)(de)接觸電(dian)阻(zu)及加強局部(bu)散(san)熱(re)能力，對于一根導線(xian)來(lai)說，整體電(dian)阻(zu)是均勻分(fen)布(bu)的(de)(de)(de)，但(dan)線(xian)鼻子的(de)(de)(de)連(lian)接處(chu)無論你用多(duo)大的(de)(de)(de)壓(ya)力安裝，其接觸部(bu)位(wei)的(de)(de)(de)電(dian)阻(zu)總是要大于導線(xian)非連(lian)接處(chu)，從而造成(cheng)局部(bu)發(fa)熱(re)嚴重，解決的(de)(de)(de)辦(ban)法就(jiu)是盡量增大接觸面積，減少接觸電(dian)阻(zu)。同時，較大的(de)(de)(de)線(xian)鼻子其散(san)熱(re)能力也(ye)將更高。線(xian)耳一般要比電(dian)纜大兩個(ge)規格左右，因為電(dian)纜有時候是壓(ya)成(cheng)扇型的(de)(de)(de)，不(bu)是純圓形，一般需要用液(ye)壓(ya)機再壓(ya)緊后(hou)使用。
