The Difference between Single-Core and Multi-Core Cables

Wires are familiar to everyone, so what is the difference between a single-core wire and a multi-core wire?

Some people will say that the single-core line is only a one-way wire, and the multi-core line refers to a multi-way wire, indeed, but the difference between the two is only these.

Single-core line and a multi-core line there are many aspects of difference, do not know with ZMS cable editor to take a look at it!

Single Core Wire

Single-core wire has only one way of wire in the insulation layer.

Advantages: strong tensile strength, not easy to mold break, easy to thread, good stability.

Disadvantages: poor heat dissipation, poor flexibility, poor resistance to bending ability.

Multi-Conductor Wires

Multi-core wire has two or more conductors in the insulation layer.

Advantages: good flexibility, good heat dissipation, good skin resistance, and good load capacity.

Disadvantages: poor tensile strength, easy to break the mold, joints should be handled well.

What is the difference between single-core and multi-core cables?

1 Single-core wire with strong tensile strength, is easier in line joints, and equipment wiring, and multi-core wire is softer.

It is suitable for multi-corner lines, which can be better bent without breaking.

2 Multi-core wire is soft for easy construction, not easy to damage, and suitable for more mobile lines, while the single-core wire is harder and easier to fix.

3 For longer distance wiring, single-core wire should be used.

The single-core wire is strong and can ensure that it will not be pulled off.

4 In the case of the same cross-sectional area, multi-core wire has a higher current carrying capacity than single-core wire, and the higher the frequency, the more obvious.

Because the current has a skin effect, go to the surface of the conductor.

Multi-core unfolded surface area is larger, so the flow rate is higher, and heat dissipation performance is also better, but the multi-core price is more expensive.

The choice of single-core or multi-core wire can be simply summarized as follows: fixed with a single-core, mobile with a multi-core.

The dark line with a single-core, and the open line with a multi-core.

Strong power with a single-core, weak power with a multi-core.

It is worth noting that: the joints of multi-core wire are easy to heat up due to poor contact, so the joints need to be dealt with.

Through the above analysis, the use of a single-strand line has certain advantages, and in terms of installation convenience, a multi-strand line dominates. Therefore, for the owners, it is recommended that you choose the line of single stocks.

From the perspective of the installer, more masters are willing to choose multiple stocks.
