                 How to correctly choose single-core cable and multi-core cable?
Wires and cables are indispensable materials in our home decoration. Before decoration, the cables need to be laid neatly. However, the wires have different specifications and parameters. Before choosing, we should have a corresponding understanding of the products.
1. What is a single core cable?

                                               
  Single-core cable means that there is only one wire inside the wire, and the cross-sectional area of the wire is relatively large
  Advantages: single-core cables are easy to operate when threading, have good stability, and are widely used for laying circuits;
  Disadvantages: The heat dissipation function is relatively poor, and it is easy to be bent.
2. What is a multi-core cable?

                                                         
  Multicore cables have two or more conductors inside
  Advantages: The current of the load is large, the power is strong, and the flexibility is stronger than that of the single-core cable;
  Disadvantages: There are many multi-core wire connectors, which need to be handled with care.
3. The difference between single-core wire and cable and multi-core wire and cable
(1) The construction is different: when wiring, the single-core cable is harder when threaded through the tube, and the connection will be more convenient, while the multi-core cable is softer and more complicated to thread.
(2) Different applicability: If you need to lay mobile lines, it is best to choose multi-core cables; for long-distance laying, choose single-core cables, which can ensure that it is not easy to be damaged during wiring.
(3) When the cross-sectional area is the same, the current carrying capacity of the multi-core cable is greater than that of the single-core cable, and the power is higher than that of the single-core cable.
(4) In terms of price: the price of multi-core cables is higher than that of single-core cables.
(5) Scope of application: single-core cable for high current, multi-core cable for weak current.

 

The above points are for reference only. Everyone has a certain understanding of the difference between the two. The specific use should be judged according to the environmental situation, and there is not much difference in nature. In addition, everyone should choose qualified wires and cables when purchasing cables.
