2022-10-25(2088)Views
There are two types of wires and cables: single core and multi core. Some users who are not familiar with them may have questions. 32 core and 41 core, both of which look like 5 cores. Is there a difference between the two? Below, the cable editor will introduce the meaning and differences between wires and cables with 32 and 41 cores.
1、 The difference between wires and cables
A wire is composed of one or several flexible wires, wrapped in a light and soft protective layer;
A cable is composed of one or several insulated wires wrapped in a tough outer layer of metal or rubber.
2、 The numbers 32 and 41 on a wire represent the number of cores in a cable. There are 2 or 3 insulated wires, 32 insulated wires, 41 insulated wires, and 5 insulated wires inside a cable, which are called 2 or 3 cores, 32 insulated wires, 41 insulated wires, and 5 insulated wires.
3、 Taking power cable YJV as an example
YJV 3 2-core
The diameter of the three phase lines (L1, L2, L3 phase lines, which have the largest diameter) of the 32 cable is the same. The diameter of the two lines is the same, and they are the zero line and the PE line. One line is used to connect the zero line (N neutral line, which has a smaller diameter compared to L1, L2, L3), and the other line is used to connect the grounding wire (PE grounding protection wire, which has a smaller diameter compared to L1, L2, L3).
