铠装电缆(lan)是一种(zhong)特殊的(de)电缆(lan),主(zhu)要用(yong)于工业和交通设(she)备(bei)的(de)用(yong)水系统。它一般由液壳(qiao),绝缘体,屏(ping)(ping)蔽体和导线组成,其中液壳(qiao),绝缘体和屏(ping)(ping)蔽体之间常(chang)常(chang)采用(yong)铠装技术(shu),形成了一种(zhong)复合(he)式外壳(qiao)结构,以保证电缆(lan)的(de)安全(quan)和可(ke)靠(kao)性(xing)。
铠(kai)装电(dian)(dian)缆(lan)主要(yao)包(bao)括(kuo):热(re)泡装电(dian)(dian)缆(lan)、金属塑料(liao)复(fu)合外壳(qiao)电(dian)(dian)缆(lan)、桥(qiao)接(jie)芯电(dian)(dian)缆(lan),相对应的用途有:彩色电(dian)(dian)视接(jie)收(shou)机用热(re)泡装电(dian)(dian)缆(lan);中频及短波电(dian)(dian)台用金属塑料(liao)复(fu)合外壳(qiao)电(dian)(dian)缆(lan);数据传输用桥(qiao)接(jie)芯电(dian)(dian)缆(lan)。
优点(dian):铠装(zhuang)电(dian)(dian)缆对(dui)电(dian)(dian)磁(ci)(ci)干扰(rao)抗性强,使用寿命(ming)长,符合国家质量(liang)标准,保证电(dian)(dian)气故障不出现;对(dui)电(dian)(dian)磁(ci)(ci)波(bo)具有(you)(you)良好的(de)(de)隔离效(xiao)(xiao)果,防(fang)止(zhi)电(dian)(dian)磁(ci)(ci)波(bo)发生干扰(rao);外壳采用阻燃材料(liao),可以有(you)(you)效(xiao)(xiao)防(fang)止(zhi)电(dian)(dian)缆着火(huo),烟火(huo)及挥发污染(ran)的(de)(de)损害;它(ta)还可以有(you)(you)效(xiao)(xiao)过(guo)滤外部(bu)环境中(zhong)的(de)(de)电(dian)(dian)磁(ci)(ci)波(bo),减少(shao)电(dian)(dian)磁(ci)(ci)波(bo)的(de)(de)损害。
缺(que)点:由于采用了(le)铠装技术,使(shi)电(dian)(dian)缆(lan)体积庞大,使(shi)电(dian)(dian)子存储器(qi)使(shi)用受到影(ying)响;价(jia)格居(ju)高(gao)不下(xia),在不影(ying)响电(dian)(dian)器(qi)使(shi)用效果的情(qing)况(kuang)下(xia),周边居(ju)民(min)的物业维修(xiu)费也会增加。
总之,铠装电(dian)缆在电(dian)气系统中是(shi)必须可(ke)靠(kao)的,它具有(you)(you)电(dian)磁干扰抗性强、寿命长等(deng)优点(dian),但是(shi)因为体积庞(pang)大和价格(ge)较高等(deng)缺点(dian),使得许(xu)多(duo)人没有(you)(you)采用,所以严格(ge)来说铠装电(dian)缆是(shi)有(you)(you)其存在的必要(yao)性的,但需要(yao)引起重视。
