There are distinctions between soft and hard wires in electrician wiring, and there are strict controls. What is the difference between the line and the hard line? The lines used for transmission of different lines are also different. Which applications use soft and hard lines, and where are their advantages and disadvantages?

The difference between soft and hard lines

The difference between the soft wire and the hard wire _ wire soft wire and hard wire which is good _ soft wire and hard wire which load is large

The concepts of “hard wire” and “soft wire” in electrical are: hard wire, single wire of solid metal with a diameter of 1 mm or more; soft wire, which is made of multiple strands of conductive metal wire with a diameter of less than 1 mm. The resulting wire. Their respective advantages and disadvantages can be examined from the following aspects:

1. Cross-sectional area. The same current carrying capacity has a small cross-sectional area and a large cross-sectional area of the flexible wire;

2, tensile strength. Strong hard line and weak soft line;

3, anti-corrosion. Strong hard line and weak soft line;

4, anti-fatigue (anti-lateral fracture). The hard line is weak and the soft line is strong;

5. Insulation strength. Hard wires and cords depend on the material and thickness of the insulation layer;

6, anti-"skin effect" (that is, the higher the current frequency, the more tends to the surface of the wire, the central part of the current, resulting in waste). The hard line is poor and the cord is better;

7. Waste recycling rate (metal recycling). The hard line is higher and the cord is lower.

The advantages and disadvantages of these hard-wired cords also determine their respective application sites. Hard-wires are often used in permanent places such as buried walls, buried areas, and outdoor areas. The flexible cables are mostly used for power supply cables for home appliances and equipment, and internal circuit boards for electrical appliances. , the connection between components.

Advantages of hard and soft lines in home improvement

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.

Chongqing's general home improvement is the use of pigeon brand wire, but the pigeon card also has the distinction of "single core hard wire - BV" and "multiple strand soft core wire BVR". 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, the hard is generally a single core wire inside, that is, the conductor is a copper wire, the soft is a wire core composed of multiple 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 to bring Kai, the mechanical strength of the hard wire is better than the soft wire, better protection cable;

6, some places where the hard wire is easy to route, 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.

Household wire soft wire and hard wire which is good

Each has its own advantages and disadvantages. When hard wire (BV type) is used, sometimes the junction box is small, the wire allowance is too inconvenient, the wire is too hard, and it is difficult to bend and the wiring is difficult. It is difficult to make the upper panel of the socket box more online. Install it. Personally recommend that the wire of 2.5mm2 and above is made of soft wire (BVR type), and the wire of 1.5mm2 or less is hard wire (BV type).

Only the soft wire is slightly higher than the hard wire. If there are conditions, it should be better to use the cord.

Which load is thick for soft and hard wires

The wire has a thickness of multiple strands and a single strand of the same 6 square load is the same, regardless of which load is large load.

Multi-strand folding resistance is not easy to break, single-stranded to adapt to the cable, the general household line with dark and bright lines are suitable for hard lines, the use of soft lines is just the lamp line or moving line, or plug the line.

Wire problem: the use of single stock has a single share, the use of multiple shares has multiple shares, each need is different, and the single stock is also a lot of strands. The problem of wiring is not a problem, and the joints that will be wired will never be loose. If you don't understand the power, you won't be able to pick up the connector.
