电(dian)(dian)线电(dian)(dian)缆工(gong)作(zuo)虽然(ran)只(zhi)是一(yi)个配(pei)套工(gong)作(zuo),但它产品品种(zhong)许多,运用规(gui)划非常(chang)遍及(ji),涉及(ji)到电(dian)(dian)力、建筑、通讯、制(zhi)造(zao)(zao)等工(gong)作(zuo),与国(guo)民经(jing)济的(de)(de)各(ge)个部门都严密相(xiang)关。电(dian)(dian)线电(dian)(dian)缆还被(bei)称为(wei)国(guo)民经(jing)济的(de)(de)“动脉”与“神经(jing)”,是运送(song)电(dian)(dian)能、传递(di)信(xin)息和制(zhi)造(zao)(zao)各(ge)种(zhong)电(dian)(dian)机、仪器、表面,完结电(dian)(dian)磁能量转(zhuan)化所不可缺少的(de)(de)基础(chu)性器材,是未来(lai)电(dian)(dian)气化、信(xin)息化社会(hui)中必要的(de)(de)基础(chu)产品,下面金联宇电(dian)(dian)缆为(wei)咱们拾掇出了一(yi)些有关电(dian)(dian)线电(dian)(dian)缆的(de)(de)底子常(chang)识!

一(yi)、在国标里,一(yi)般(ban)B字母开始的电(dian)(dian)(dian)缆如BV、BVV、BVR都是(shi)布(bu)(bu)电(dian)(dian)(dian)线(xian)(xian)(xian),按名(ming)字了(le)解就(jiu)是(shi)固定布(bu)(bu)线(xian)(xian)(xian)电(dian)(dian)(dian)缆都可称为布(bu)(bu)电(dian)(dian)(dian)线(xian)(xian)(xian)。广义来(lai)讲,布(bu)(bu)电(dian)(dian)(dian)线(xian)(xian)(xian)只是(shi)一(yi)个范称,并不(bu)说哪(na)类电(dian)(dian)(dian)缆才是(shi)布(bu)(bu)电(dian)(dian)(dian)线(xian)(xian)(xian),多数是(shi)指建筑物内部固定布(bu)(bu)线(xian)(xian)(xian)电(dian)(dian)(dian)缆(包(bao)括(kuo)但不(bu)限于(yu)电(dian)(dian)(dian)力线(xian)(xian)(xian)、网络通讯、有线(xian)(xian)(xian)电(dian)(dian)(dian)视、光纤等)。

 

二(er)、通过(guo)布电线(xian)(xian)的(de)(de)(de)类型,大(da)致可以(yi)知(zhi)道导线(xian)(xian)质(zhi)料(liao)(liao),绝缘或护(hu)套的(de)(de)(de)材料(liao)(liao):以(yi)BV线(xian)(xian)为例,字母B,是(shi)布电线(xian)(xian)的(de)(de)(de)拼音简称。字母V,是(shi)外面(mian)的(de)(de)(de)那层(ceng)塑料(liao)(liao)的(de)(de)(de)质(zhi)料(liao)(liao)。V,是(shi)聚氯乙烯PVC的(de)(de)(de)简称。外面(mian)那层(ceng)塑料(liao)(liao),可以(yi)叫绝缘,也可以(yi)叫护(hu)套,如果是(shi)BVV则标明(ming)有两层(ceng)护(hu)套。线(xian)(xian)芯质(zhi)料(liao)(liao)这块,铜的(de)(de)(de)代号是(shi)T,一般略掉不写。如果是(shi)铝导线(xian)(xian),L不省掉。

 

三(san)、布(bu)电(dian)(dian)线(xian)(xian)(xian)的(de)(de)横截(jie)(jie)面积(ji):以BV2.5平方(fang)为例,2.5平方(fang)是(shi)横截(jie)(jie)面积(ji),单(dan)位是(shi)平方(fang)毫米(mi)。往常说的(de)(de)多少方(fang)的(de)(de)线(xian)(xian)(xian),是(shi)指横截(jie)(jie)面积(ji)。知(zhi)道了(le)横截(jie)(jie)面积(ji),线(xian)(xian)(xian)芯的(de)(de)直径就(jiu)知(zhi)道了(le)。要注意(yi)的(de)(de)是(shi)有许多人会把横截(jie)(jie)面积(ji)作为判别载(zai)流量合不(bu)合格(ge)的(de)(de)规范,这(zhei)其实是(shi)很不(bu)科学的(de)(de),现在(zai)市(shi)道上有70~80%的(de)(de)电(dian)(dian)线(xian)(xian)(xian)是(shi)不(bu)符(fu)合规范的(de)(de)非标电(dian)(dian)线(xian)(xian)(xian),所用的(de)(de)铜质量也欠佳,这(zhei)样的(de)(de)电(dian)(dian)线(xian)(xian)(xian)即使线(xian)(xian)(xian)方(fang)够了(le),电(dian)(dian)阻依然(ran)比较大,载(zai)流量也并不(bu)合格(ge),而像(xiang)金联宇电(dian)(dian)缆运(yun)用的(de)(de)是(shi)99.99%的(de)(de)无氧铜,所以不(bu)论(lun)是(shi)在(zai)线(xian)(xian)(xian)方(fang)和(he)载(zai)流量等(deng)各(ge)方(fang)面都(dou)能(neng)完美合格(ge),这(zhei)才是(shi)国(guo)标电(dian)(dian)缆该有的(de)(de)姿势。

 

四(si)、低压电(dian)(dian)缆的(de)类型规范:有了(le)布(bu)电(dian)(dian)线的(de)烘托,电(dian)(dian)缆可以举个实践比如(ru),例如(ru)VV3*50,它代表(biao)的(de)含(han)义是,铜芯,PVC绝缘,PVC护(hu)(hu)套(tao),3根50平方的(de)电(dian)(dian)力电(dian)(dian)缆。常(chang)用的(de)塑料,除了(le)PVC,也能参与一些(xie)耐候(hou),耐火(huo),阻(zu)燃等(deng)有关的(de)材料。有时(shi),会看到(dao)VV22或VV23等(deng)这(zhei)(zhei)样的(de)标(biao)明,22标(biao)明双(shuang)钢(gang)带(dai)绕包铠(kai)装PVC外(wai)护(hu)(hu)套(tao),23代表(biao)双(shuang)钢(gang)带(dai)绕包铠(kai)装聚乙烯护(hu)(hu)套(tao),这(zhei)(zhei)些(xie)代号都有有关技术规范。

 

五、绝缘(yuan)等级:比如低(di)压电(dian)缆的0.6/1KV,或(huo)许高压电(dian)缆的8.7/15KV,即(ji)为适(shi)用(yong)于固定敷设(she)在额定电(dian)压1KV和15KV及(ji)以下的输(shu)配(pei)电(dian)线路(lu)上(shang)。

 

六、其他类(lei)(lei)(lei)型:钢绞(jiao)线(xian)(xian),拉(la)电(dian)线(xian)(xian)杆用。高(gao)压缆(lan)(lan),一般安装公司(si)常接触,在某(mou)些地(di)区,一般从高(gao)压线(xian)(xian)到(dao)变压器(qi)那段(duan),长(zhang)度是底子(zi)固(gu)定的(de)(de)。农用地(di)埋线(xian)(xian)NLVV,机械强度极低(di),现在逐渐被(bei)挑选了。带绝缘(yuan)的(de)(de)高(gao)压架空线(xian)(xian), 里(li)面的(de)(de)那个钢芯,除了固(gu)定稳(wen)固(gu)的(de)(de)作用,应(ying)该(gai)还有趋肤效应(ying)的(de)(de)要素。控制电(dian)缆(lan)(lan)、信号电(dian)缆(lan)(lan)和特种电(dian)缆(lan)(lan)等(deng),它们的(de)(de)类(lei)(lei)(lei)型规(gui)范、出(chu)产工艺,底子(zi)类(lei)(lei)(lei)似。

 

七、弯(wan)(wan)曲(qu)(qu)半径(jing):电(dian)缆(lan)有弯(wan)(wan)曲(qu)(qu)半径(jing)要(yao)求,所(suo)以(yi)不同粗细的线(xian)缆(lan)制品,用的电(dian)缆(lan)盘的直径(jing)不一样(yang),电(dian)缆(lan)敷设时最小弯(wan)(wan)曲(qu)(qu)半径(jing)(D为(wei)电(dian)缆(lan)外径(jing)):单芯(xin)无铠装(zhuang)电(dian)缆(lan)为(wei)20D,多芯(xin)无铠装(zhuang)电(dian)缆(lan)为(wei)15D,单芯(xin)铠装(zhuang)电(dian)缆(lan)为(wei)15D,多芯(xin)铠装(zhuang)电(dian)缆(lan)为(wei)12D。

终究,提示咱们,选购电线电缆时(shi)一(yi)(yi)定要(yao)认准正规(gui)的出(chu)产(chan)(chan)厂家,检查清(qing)楚质量(liang),不(bu)要(yao)因为价格(ge)实惠公(gong)正而去购买(mai)一(yi)(yi)些非合格(ge)的电线。金联宇电缆有(you)限(xian)公(gong)司是(shi)一(yi)(yi)家集研发、制造和出(chu)售为一(yi)(yi)体的大(da)型电线电缆企业,产(chan)(chan)品(pin)热销全国(guo)(guo)各地(di),且(qie)出(chu)产(chan)(chan)的全部(bu)产(chan)(chan)品(pin)保(bao)证(zheng)全国(guo)(guo)抽检合格(ge),质量(liang)保(bao)证(zheng)、服务至上,深得宽广顾(gu)客的高度赞誉(yu)。
