Customized Single-core cable from China belongs to hard wire (BV wire), and only 10mm ² The wires within are called single core. The multi-core wire can be divided into multi core wire (BV wire) and multi-core flexible wire (BVR wire). E.g. 2.5mm ² Wire, customized Single-core cable is composed of 1 strand of wire with diameter of 1.78mm; The multi core wire is composed of 7 conductors with a diameter of 0.68mm; The Best multi core wire from China is composed of 19 conductors with a diameter of 0.41mm.

Customized Single-core cable from China is recommended for home installation. Let's take a look at the following advantages:

1. Firm

The external force of customized household wire decoration is to resist tension and pressure. On the hardness level, customized Single-core cable from China is better than others - the multi core wire is very easy to break the copper wire in the process of pulling and extruding, resulting in a decrease in the cable current carrying capacity - especially the fine copper wire with an outer diameter of 0.41mm.

2. Large current carrying capacity of customized household wire from China

In short line, low frequency, low voltage and low current lines (skin effect is not considered), the cable current carrying capacity of customized Single-core cable from China is higher than that of multi core wire. PS: If skin effect is fully considered, the cable current carrying capacity of customized multi core wire from China will be higher - this is also 10mm ² There is no Single-core cable above.

3. BV wire and BVR wire

Compared with BVR line, BV line has weak bending strength and skin effect resistance. However, because of the simple processing technology, high quality and low price household wire, it is more suitable for home decoration.

In almost all power circuits except for indoor decoration and pavement, BVR line is the most common one - BV line has poor adaptability, especially when the metal plate must be frequently bent, which will do great harm to the service life of BV line, and the wiring difficulty coefficient will also increase a lot.

For customized multi core wire from China, it is the square between Single-core cable and BVR wire - it has a certain anti skin effect, but its bending strength is still insufficient.
