电线电缆中BV、BLV等符号含义
The meaning of BV, BLV and other symbols in wire and cable
这些符号都是电线的一些型号,B系列归类属于布电线,所以开头用B,电压:300/500V 电线按用途分为电磁线和通用绝缘电线。绝缘电线又称为布电线。
These symbols are some models of wires. Series B is classified as distribution wire, so it is used at the beginning, voltage: 300 / 500V. Wires are divided into electromagnetic wires and general insulated wires according to their uses. Insulated wire is also called cloth wire.
绝缘电线(布电线)是指包覆绝缘层的电线,包括各种连接线、安装线。
Insulated wire (wiring) refers to the wire covered with insulating layer, including various connecting wires and installation wires.
V就是PVC聚氯乙烯,也就是(塑料)
V is PVC, PVC, or plastic
L就是铝芯的代码
L is the code of aluminum core
T就是铜芯的代码(一般省略不写)
T is the code of copper core
R就是(软)的意思,要做到软,就是增加导体根数
R means (soft). To be soft, it means to increase the number of conductors
BV铜芯聚氯乙烯绝缘电线
Bv copper core PVC insulated wire
BLV铝芯聚氯乙烯绝缘电线
BLV aluminum core PVC insulated wire
BVR铜芯聚氯乙烯绝缘软电线
BVR copper core PVC insulated flexible wire
以上电线结构:导体+绝缘
Above wire structure: conductor + insulation
拿2.5mm2为例:
Take 2.5mm2 as an example
BV是1根直径1.78mm和7根0.68两种
BV is 1.78mm in diameter and 7 0.68mm in diameter
BLV是1根直径1.78mm
The BLV is 1. 78mm in diameter
BVR是19根直径0.41mm
BVR is 19, diameter 0.41mm
RV铜芯聚氯乙烯绝缘连接软电线
RV copper core PVC insulated connection flexible wire
它比BVR更软,还是2.5是49根0.25mm铜丝
It is softer than BVR, or 2.5 is 49 pieces of 0.25mm copper wire
RVV铜芯聚氯乙烯绝缘聚氯乙烯护套连接软电线
RVV copper core PVC insulated PVC sheathed connection flexible wire
比RV多了一层塑料护套
One more layer of plastic sheath than RV
另外:我们最常用的“护套线”
What's more, our most commonly used "sheath wire"
