绍兴雷鹰科技生产(chan)的(de)(de)包(bao)钢(gang)接(jie)地(di)(di)(di)(di)(di)绞(jiao)(jiao)线(xian)(xian)由一定根(gen)数的(de)(de)铜包(bao)钢(gang)单线(xian)(xian)绞(jiao)(jiao)制而成(cheng)。电(dian)镀铜包(bao)钢(gang)单线(xian)(xian)及绞(jiao)(jiao)线(xian)(xian)是含99.9%的(de)(de)电(dian)解铜均匀电(dian)镀到低(di)碳钢(gang)芯上加工而成(cheng)的(de)(de)新型符(fu)合材(cai)料，该产(chan)品既有(you)钢(gang)的(de)(de)强(qiang)度和韧(ren)性，又有(you)铜的(de)(de)良好(hao)导电(dian)性和耐腐蚀性能。相(xiang)比铜单线(xian)(xian)具有(you)密度小，强(qiang)度高，造价(jia)低(di)等优点，是传统纯铜单线(xian)(xian)的(de)(de)更新换代产(chan)品。铜包(bao)钢(gang)接(jie)地(di)(di)(di)(di)(di)绞(jiao)(jiao)线(xian)(xian)一般环(huan)境和潮湿、盐(yan)碱、酸性土壤极产(chan)生化学(xue)腐蚀介质的(de)(de)特殊环(huan)境高要求的(de)(de)工作接(jie)地(di)(di)(di)(di)(di)、保(bao)护(hu)接(jie)地(di)(di)(di)(di)(di)、防雷接(jie)地(di)(di)(di)(di)(di)、防静(jing)电(dian)接(jie)地(di)(di)(di)(di)(di)的(de)(de)水平接(jie)地(di)(di)(di)(di)(di)体(ti)。

雷鹰科技生产的(de)(de)铜包钢(gang)(gang)线是(shi)以(yi)低(di)碳(tan)钢(gang)(gang)材为(wei)基芯，经(jing)镀铜加工而成的(de)(de)复合材料。具有(you)可焊性和(he)耐腐蚀(shi)性，良好(hao)的(de)(de)导(dao)(dao)电性等，尤(you)其是(shi)在高频(pin)下，由于趋(qu)肤(fu)效应随着频(pin)率的(de)(de)增(zeng)加而增(zeng)大，因而铜包钢(gang)(gang)线的(de)(de)导(dao)(dao)电性能可与同截(jie)面(mian)积(ji)的(de)(de)铜线相(xiang)比(bi)拟。具有(you)节铜材、造价低(di)等优点，是(shi)传统(tong)铜线的(de)(de)换代产品。铜包钢(gang)(gang)绞线及单(dan)(dan)丝表面(mian)应光洁,，不得有(you)裂(lie)痕及裂(lie)缝,，漏镀及划伤(shang)等缺(que)陷(xian)。绞线的(de)(de)通(tong)条直径和(he)捻距(ju)应均匀(yun)，切断后应不松(song)散。绞线内单(dan)(dan)丝应紧密(mi)绞合，不得有(you)交错(cuo)、断裂(lie)和(he)弯折。铜覆钢(gang)(gang)绞线是(shi)将含量为(wei)99.9%的(de)(de)电解(jie)铜分(fen)子均匀(yun)电镀到低(di)碳(tan)钢(gang)(gang)芯上加工而成的(de)(de)新型复合材料。

铜包(bao)钢(gang)接地绞线没有经(jing)过适当的(de)(de)(de)线路衰减，由于它(ta)较(jiao)尖，即这(zhei)个(ge)电(dian)容(rong)器的(de)(de)(de)两(liang)极板正对面积很(hen)小，电(dian)容(rong)也就(jiu)很(hen)小，也就(jiu)是(shi)说它(ta)所能(neng)容(rong)纳的(de)(de)(de)电(dian)荷很(hen)少(shao)。而它(ta)又聚集了(le)大部分电(dian)荷，所以(yi)(yi)，当云(yun)(yun)层(ceng)上电(dian)荷较(jiao)多时(shi)，避(bi)(bi)雷(lei)(lei)针(zhen)(zhen)与云(yun)(yun)层(ceng)之间的(de)(de)(de)空气就(jiu)很(hen)容(rong)易被(bei)击(ji)穿，成(cheng)为(wei)导体(ti)。这(zhei)样(yang)，带(dai)电(dian)云(yun)(yun)层(ceng)与避(bi)(bi)雷(lei)(lei)针(zhen)(zhen)形成(cheng)通路，而避(bi)(bi)雷(lei)(lei)针(zhen)(zhen)又是(shi)接地的(de)(de)(de)。避(bi)(bi)雷(lei)(lei)针(zhen)(zhen)就(jiu)可以(yi)(yi)把云(yun)(yun)层(ceng)上的(de)(de)(de)电(dian)荷导人大地，使其不(bu)对高(gao)层(ceng)建(jian)筑构成(cheng)危(wei)险。铜包(bao)钢(gang)接地绞线的(de)(de)(de)防(fang)(fang)(fang)护(hu)等级又不(bu)匹配，一(yi)定要超(chao)过屋子的(de)(de)(de)至高(gao)点，一(yi)般的(de)(de)(de)布置方式是(shi)在(zai)(zai)房顶周(zhou)围用(yong)(yong)钢(gang)筋围一(yi)圈，比如只用(yong)(yong)一(yi)个(ge)20kV做(zuo)为(wei)线路防(fang)(fang)(fang)雷(lei)(lei)防(fang)(fang)(fang)护(hu)，四角各立一(yi)个(ge)1到(dao)(dao)2米的(de)(de)(de)钢(gang)筋，在(zai)(zai)没有人出入(ru)的(de)(de)(de)一(yi)侧用(yong)(yong)钢(gang)筋接到(dao)(dao)地面，在(zai)(zai)接地位置焊(han)块(kuai)一(yi)平米左右的(de)(de)(de)铁板。而雷(lei)(lei)电(dian)波侵入(ru)超(chao)过60kV，这(zhei)样(yang)的(de)(de)(de)结果就(jiu)是(shi)防(fang)(fang)(fang)雷(lei)(lei)器被(bei)击(ji)坏(huai)，买入(ru)地下。这(zhei)样(yang)肯定安全。避(bi)(bi)雷(lei)(lei)针(zhen)(zhen)就(jiu)聚集了(le)大部分电(dian)荷。避(bi)(bi)雷(lei)(lei)针(zhen)(zhen)又与这(zhei)些带(dai)电(dian)云(yun)(yun)层(ceng)形成(cheng)了(le)一(yi)个(ge)电(dian)容(rong)器，无法起到(dao)(dao)防(fang)(fang)(fang)护(hu)作用(yong)(yong)的(de)(de)(de)防(fang)(fang)(fang)雷(lei)(lei)措施起不(bu)到(dao)(dao)什么实际的(de)(de)(de)作用(yong)(yong)。保(bao)证了(le)它(ta)的(de)(de)(de)安全。铜包(bao)钢(gang)还具有良好的(de)(de)(de)环保(bao)性能(neng)。可以(yi)(yi)回收再(zai)利用(yong)(yong)，减少(shao)资源浪费。浙(zhe)江热浸(jin)连铸铜包(bao)钢(gang)涂层(ceng)
