Because of the small cross-sectional area ratio, it is not easy to be oxidized, resistant to short-circuit current impact and has a relatively long service life.

Disadvantages of single-core wire

Advantages of single-core wire

Because of the small cross-sectional area ratio, it is not easy to be oxidized, resistant to short-circuit current impact and has a relatively long service life.

Disadvantages of single-core wire

The wire is hard, so it is inconvenient to pull the wire in some places, and it is not easy to straighten after bending, and it is easy to damage the wire after repeated bending.

Advantages of multi-core cable

Multicore cable refers to a cable with more than one insulated core wire, which reduces the skin effect of the cable, thus reducing the loss of the line.

Disadvantages of multi-core cable

Poor tensile strength, easy to mildew, poor surge current resistance and inconvenient molding.

Which is better, single-core cable or multi-core cable?

Among the conductors with the same cross-sectional area, the cost of single-core conductor is cheaper than that of multi-core, and multi-core conductor is slightly more expensive. When installing the pipe, the single-core wire appears hard, and the multi-core wire is soft, which is easy to wire. After installation, in actual use, single-core multi-core
