电线有那些名称和型号?
电线电缆不管家庭还是其它领域,其身影随处可见。在电能的输送及信号的传递扮演者重要角色,因此电线电缆各行各业都离不开它。看到的电线电缆有各式各样的,令人眼花缭乱。虽然它的完整命名复杂,但是具体的产品命名都有原则可寻。(中冀建材李素婷)
电力电缆线型号各部分的代号及含义
绝缘种类、导体材料、内护套、特征、控制层、外被层几个部分。绝缘种类有聚氯乙烯(V)、聚乙烯(Y)、橡胶(X)、交联聚乙烯(YJ)、纸(Z)。线缆常用的导体材料有铝(L)、铜(T),通常情况下铜代号T都省略的。内护套有聚氯乙烯护套(V)、聚乙烯护套(Y)、铝护套(L)、橡胶护套(H)、氯丁橡胶护套(F)。特征有不滴流(D)、分相(F)、贫油干绝缘或屏蔽(P)、直流(Z)、充油(CY)。控制层和外被层以数字表示,前者0 2 3 4 分别表示无、双钢带、细钢丝、粗钢丝。后者0 1 2 3分别表示无、纤维外被、聚氯乙烯护套、聚乙烯护套。阻燃电缆其代号前加ZR、耐火电缆在代号前加NH。
电缆线平方数及直径换算
有时看到的电线规格并不是国家标准,有的是美制也有的英制的,这也是国际常用电缆的三种标准。例如通常听说某某人说电线几平方,就是国标规定的标称值,作为用户就可以根据电线电缆的负荷来合理选用它。这里说的几平方是没有将单位加入,其单位是平方毫米,指的就是电线电缆的横截面积。知道线缆的横截面积平方计算电线直径或者知道直径计算横截面积,可用圆形面积公式计算(S=πr^2或S=πD^2/4)。
常用的小规格电缆
仪器仪表、电器、控制安装、配电装置等电缆常用的是RVVP和KVVP,就是铜芯聚氯乙烯绝缘屏蔽聚氯乙烯护套软电缆和聚氯乙烯护套编织屏蔽电缆。弱电方面的电源线、信号线、家用电器、动力照明等用线可用RVV,聚氯乙烯绝缘软电缆。AVVR聚氯乙烯护套安装用软电缆、RV、RVP聚氯乙烯绝缘电缆、聚氯乙烯屏蔽电缆。RVS、RVB适用于家电、小型电动工具仪表的用线,BV BVR聚氯乙烯绝缘电缆,可用于仪器仪表、动力照明接电源用。例如局域网用的有UTP,有线电视、宽带等用线SYWV、SYKV等。
对于电线其实平常接触多了且记住些基本原则,时不时做个笔记,可或多或少会得到收获。
楼主提的问题范围是有点大,但是可以分类解释,电线电缆共分为5大类,分别为,1、电力电缆;
2、裸电线及裸导体制品 3、漆包线 4、电器装备用电缆 5、通信电缆及光缆
每一分类我简单写些型号,如1、电力电缆YJV VV等等 2、裸电线及裸导体制品如LGJ钢芯铝绞线 3、漆包线QZ(G)1/155等等 4、电器装备用电缆 如常用的BV线 5、通信电缆及光缆如普通的电话线网线等等都属于通信电缆一类 ,如果楼主提供更加确切的线索,我将详细回答,
提问即有收获
