Which one has the longest service life, single-core wire or multi-core wire

2023-02-07 16:52

The service life of multi-core wire is long. The following reasons can be referred to:
1. In terms of structure: single-core wire has only one conductor, while multi-core wire has multiple conductors, so their current-carrying capacity is different, resulting in different load power. In addition, with the same cross-sectional area, the service life of multi-core wire will be longer because its surface area is larger than that of single-core wire.
2. Wiring: the single-core wire is made of hard material, which is not suitable for bending when connecting, while the multi-core wire is made of soft material, which can be used not only when installing in a straight line, but also can be bent at will under other circumstances. Therefore, compared with the single-core wire, the multi-core wire can be bent to extend its service life, and has a wide range of applications.
3. In terms of price: single core wire uses less materials and low production cost, while multi-core wire uses more materials and has high quality of materials, so its production cost is relatively high and its service life is longer than that of single core wire.
