3、多芯導(dǎo)線截面在6mm2以內(nèi)者，計(jì)算有端子外部接線，超過6mm2時(shí)，視為截面較大，計(jì)算焊（壓）接線端子或者壓銅接線端子（通常情況下用壓銅接線端子） 4、接線端子的材質(zhì)必須與導(dǎo)線材質(zhì)相同。 5、10mm單芯及以下或2.5mm多芯及以下的銅導(dǎo)線套用外部無端子接線，而16mm的單芯或4mm的多芯銅導(dǎo)線套用壓接端子的子目。但由于有的現(xiàn)場16mm的導(dǎo)線壓接端子后難以放入塑殼開關(guān)，所以*計(jì)其零線壓接端子，地線和火線計(jì)為外部無端子接線。北侖區(qū)質(zhì)量端子哪家好慈溪市日豐通信設(shè)備有限公司的端子好不好？</p><div

1、銅接線端子是給銅電纜壓接接線端子用的。整體是純銅。 </p> <p> 不銹鋼接線端子是給鋁電纜壓接接線端子用的。壓線管部分是鋁，螺絲眼部分是銅。 </p> <p> 2、導(dǎo)線端子的工作特性是連接與導(dǎo)電，所以制作端子的材料也要滿足它的工作條件。 </p> <p> 導(dǎo)電比較好的是金、銀、銅，前兩者的造價(jià)太高，純銅相對(duì)成本低廉，還能滿足它的工藝要求，所以現(xiàn)在的導(dǎo)線端子大都選用純銅制作。 </p> <p> 不銹鋼因?yàn)榧尤肓算t、鈮、鎳等合金元素，加大了電阻使其導(dǎo)電性能有效下降，不適合用來做導(dǎo)線端子。端子的用途是什么呢？</p><div
