電氣端子排接線，分為有端子接線和無端子接線。無端子接線時，導線直接壓接在端子排接線柱上；有端子接線時，導線須套上接線端子后再壓接在端子排接線柱上。接線端子上應標注該連接導線的線號（二次回路）或?qū)Ь€的相序（一次回路），以利維修。接線端子有定型成品。 </p> <p> <br /> </p> <p> 二 </p> <p> 1、單芯導線截面積在6mm2以內(nèi)者，計算無端子外部接線，超過6mm2時，視為截面較大，計算焊（壓）接線端子。 </p> <p> 2、多芯導線截面在6mm2以內(nèi)者，計算有端子外部接線，超過6mm2時，視為截面較大，計算焊（壓）接線端子。 </p> <p> 3、接線端子的材質(zhì)必須與導線材質(zhì)相同。 </p> <p>

導電**百好的是金、銀、銅，前兩者的造價太高，純銅相對成本低廉度，還能滿足它的工藝要求，所以現(xiàn)在的導線端子大都選用純銅制作 </p> <p> 不銹鋼因為加入了鉻、鈮、鎳等合金元素，加大了電阻使其導電性能有效下降，不適合問用來做導線端子 </p> <p> 導線端子的硬度不宜太大，硬度太大結(jié)合不好，端子的有效接觸答面會變小，導通電流的截面積也就會受限，這就是為什么要在端子表面掛錫的原因，錫的硬度比較軟，可版以使端子的結(jié)合面充分結(jié)合 </p> <p> 你看到的端子發(fā)亮誤以為是不銹鋼，可能就是掛過錫不久的端子，區(qū)分端子材質(zhì)的方法之一就是用權(quán)刀刮一刮，看里面是純銅、黃銅還是純鋁浙江優(yōu)良端子需要多少錢</p><p
