Is YJV3+2 the same as YJV4+1?
There are single-core and multi-core wires and cables. Some customers may have questions. 3+2 cores and 4+1 cores both look like 5 cores. So is there any difference between the two?
Do you all know the difference between wires and cables? A wire is composed of one or several soft conductors covered with a light and soft sheath; a cable is composed of one or several insulated conductors covered with a tough outer layer made of metal or rubber.
The 3+2 and 4+1 on the wire represent the number of cores of a cable. There are 2 or 3, 3+2, 4+1, and 5 wires in a cable that are insulated from each other, which are called respectively. 2 core or 3 core, 3+2 core, 4+1 core, 5 core wire.
Take the YJV cable as an example below. The 3 of the 3+2 cable is the three phase wires (L1, L2, L3 phase wires, these three wires have the largest diameters). The diameters of the wires are the same. The 2 is the neutral wire and the PE wire. One wire is used One line is used to connect the neutral line (N neutral line, this diameter is smaller than L1, L2, L3), and one line is used to connect the ground wire (PE ground protection line, this diameter is also smaller than L1, L2, L3).
YJV 4+1 core, 4+1 cable means that the diameter of the three phase wires and the neutral wire are the same size, 1 means that the PE ground wire has one diameter alone; 4+1 means that a cable consists of 4 wires, one of which is used for It can be connected to the live wire (L1 phase wire), one wire to the neutral wire (N neutral wire), and one wire to the ground wire (PE ground protection wire).
Now do you know the difference between YJV3+2 and YJV4+1?
