The difference between hard and soft lines

Concealed works in home improvement are especially important, especially when the pipeline is buried. Therefore, concealed projects are the most important thing to pay attention to.

The price of "multi-strand soft core wire BVR" is about 10 more expensive than the ordinary "single-core hard wire-BV".

Among them, the commonly used insulating materials for electric wires are polyvinyl chloride and polyethylene, polyvinyl chloride is represented by "V", and polyethylene is represented by "Y".

1, one hard, one soft;

2. Hard is generally a single core wire inside, that is, the conductor is a copper wire, and the soft one is a wire core composed of a plurality of copper wires;

3, the hard wire production process is relatively simpler than the soft line;

4, high-frequency circuit soft wire than hard wire current carrying capacity, skin effect.

5, if it is hard because of the belt, the mechanical strength of the hard wire is better than the soft wire, better protection of the cable;

6. In some places, hard wires are easy to be wired, and some places are easy to wire.

The hard wire is also called plastic copper wire. The hard wire below 10 square is usually a single wire, and the household wire generally does not exceed 6 square.

The flexible wire is also called a sheathed wire, which is generally a multi-strand wire, that is, a plurality of copper wires are entangled inside.

As can be seen from the difficulty of the production process, the same square soft line is relatively expensive compared to the hard line.
