The decoration of the clear water room needs to be wired by itself, is it better to use a single thi

It is better to use a single strand because it is easy to operate when wiring; The wiring of multiple strands needs to be tinned, which is generally inconvenient to operate at home; Joints without tinning are easy to heat up and have poor contact;

It seems that your wiring is surface-mounted, you can consider using surface-facing PVC plastic pipes or plastic trunking for wiring, and use junction boxes together; To be horizontal and vertical, it is advisable to lay along the skirting and the corners of the wall under the roof to be more beautiful;

Pay attention to the difference between circuits, lighting, sockets, and air conditioners are separated from each other for easy control and easy maintenance;

Ordinary or square copper plastic wires for lighting can be used, 2, and the switch will be increased accordingly according to the control;

Ordinary sockets can be squared with copper and plastic wires; 3 roots; If there are more sockets, it can be divided into 2 circuits;

The air conditioner can use 4 square copper plastic wires;

Before the arrangement, it is best to have a sketch to guide, **need lights, **need switches, **need sockets, etc., wire pipes or trunkings can be considered for public use, the number of layouts has been reduced, and the distribution box is appropriately installed for line branches or maintenance, etc.;

As long as the single-strand copper core wire is used for home decoration, the millimeter square is used for lighting, and the air conditioning is 4 mm square.

I don't understand this.

Hehe. It's best to ask at the store where you bought the wire.

Just ask a few more.

The main gate is 60C, and the opening is 30C, which I asked the electrician at our site last time.

If it is not easy to trip, all the nodes must be tied firmly and wrapped with tape, and the electricity at home must be safe, and the ground wire must be connected.

There is also to consider the layout of the whole room, where to use the socket, where to place the light switch in the room (preferably connected to the dual control).

Including weak current (** line, network cable, cable TV line, etc.).

The multi-strand wire is good, and the general household electricity will not trip so easily!

There is no difference between single strand and multiple strands in terms of safety, as long as the copper core is selected according to the power consumption, the wire with a large enough copper core can be guaranteed to be safe, generally not more than 1 kilowatt per square millimeter, as for tripping, it is also selected according to your electricity consumption, the rated current is about a times of your electricity current, and it is easy to jump if you choose a small one.

ps: I am also from Guangxi,

If the cement floor of the blank house is used temporarily, the floor leather can be directly laid, and the floor leather needs to be leveled and laid after the light is leveled and collected for long-term use.

Generally, the family should be divided into socket lines and lighting wires, which are controlled separately.

The zero live wire of the socket is 4 square single-strand copper core wire, and the ground wire should be multi-strand copper core wire.

The lighting wire can be a thin copper core wire or a single strand aluminum core wire for cost saving.

Home decoration lighting should be squared, sockets should be divided into several circuits, air conditioning one trip, kitchen trip, bedroom trip, bathroom trip, each trip should be 4 square meters, single-phase electricity zero line must be the same specification as the live wire, because the zero line and the live wire current is the same.

Generally, a single-strand copper wire of 4 square meters in a family can be used, and if the electricity consumption is large, you can choose 6 square meters.

The copper core wire is single-stranded, and the zero line (air conditioner is open) should also be so that the current and voltage are stable. The number of lines to use will be calculated for you.

The zero line of the live wire is a phase wire and must be of equal diameter. The main line looks at the total power, the secondary line looks at the good point of the single strand of electrical appliances, and the circuit diagram calculates the quality of the line to see the copper and wire diameter and protective cover.

The neutral line of the fire wire must be the same - because it is a series relationship, (4 to 6 copper cores are enough for the main circuit), and each branch can be used.

Home improvement copper wire, is it better to use a single strand or multiple strands? What is the difference between a BV line and a BVR line?

Generally speaking, the live wire and the neutral wire must use the same thickness of the cable as well, (you think, since the current has 1 ampere outflow, it is natural to have 1a flow, if the thickness is different, shouldn't it be measured according to the standard of the fine wire?) If there is a ground wire, the ground wire can be finely dotted, but the ground wire should not be fused. When wiring, it is best to consider the amount of household appliances in the future, so it is better to have a slightly thicker line.

In terms of affordability, it is better to choose a multi-strand line. Generally squared foot also. It is best to use 4 square meters for high power such as air conditioners. The zero line is all squared for home decoration. As long as the line is a national standard, it will do.

A single-strand copper core for household electricity is good. General lighting can be used, air conditioning should be used, and it doesn't matter if the zero line can be smaller. Now there are many different brands on the market, and most consumers recognize them as silver fir and yanggong.

** at 200-250 yuan 100 meters (one volume).

Home improvement wires must be made of plastic copper wires, the general socket is a three-strand wire, divided into colors, distinguishing between the live wire zero line and the grounding wire, the lamp is a two-strand wire, the live wire and the neutral wire, and grounding can also be installed. Wire into the wall must use a line pipe, generally use PVC pipe. The wires are generally squared, and the water heater, kitchen treasure, and air conditioner are suitable for 4 square wires.

Remember, never use a sheath wire! It is a wire with three strands of wire together, and many fire accidents are caused by sheath wires!

Multi-strand line is better, which is convenient for later maintenance.

Answer kiss, interior decoration with a single strand is good. Because the single strand is not easy to oxidize, only the surface part of the single strand wire will be oxidized, and the middle part will not be oxidized, which is more durable.

Kiss, interior decoration with a single strand is good. Because the single strand is not easy to oxidize, only the surface part of the single strand wire will be oxidized, and the middle part will not be oxidized, which is more durable.

The multi-strand wire that has been used for a long time, and the thin copper wire of many multi-strand wires have been oxidized and broken, so that the cross-sectional area of the wire is reduced, and the potential safety hazard of electricity is increased.

The most important thing is safety, so I would recommend that you choose a single strand.

The disadvantage of a single strand is that it is not easy to construct. The rest are pluses.

The advantage of multi-strand line is that it is easy to construct. The disadvantage is that the wires are not tightly connected. The wire connector should also be hung with tin [specification].

Each has its pros and cons! The so-called single strand and multi-strand should be BV and BVR according to the standard, BVR wire is plastic copper flexible wire, BVR wire is more complex than BV wire in terms of manufacturing process, and better than BV wire in terms of conductivity. Therefore, it is more expensive than BVR wire, and because BVR wire is a multi-core wire, it must be brushed with tin when installing, and the installation process is more complex than BV line.

It is not that the BVR line cannot be used, but its cost is high and the installation process is complicated. As long as the functional requirements can be met, there is no need to use a BVR cable.

Household use of a single strand on the line, multi-strand soft suitable for external use, home line is fixed, single strand is the best.

What is single-strand or multi-stranded?

Wire??

Single-core and multi-core have their own pros and cons, and you can choose according to your own household power distribution!

The electrical safety regulations stipulate that cables with voltage levels of 35kV and below are grounded at both ends, because most of these cables are three-core cables.

In normal operation, the sum of the currents flowing through the three cores is zero, and there is basically no flux outside the aluminum ladle or metal shield, so that there is basically no induced voltage at both ends of the aluminum ladle or metal shield, so there will be no induced current flowing through the aluminum clad or metal shield after the two ends are grounded.

However, when the voltage exceeds 35kV, most of them use single-core cables, and the relationship between its core and metal shield can be regarded as the relationship between the coil and the iron core in the primary winding of a transformer.

When the core of a single-core cable passes through the current, there will be a magnetic field line cross-chained aluminum package or metal shield, so that the induced voltage appears at both ends of it.

Power cables are generally composed of wires, insulation, and protective layers, including single-core, double-core, and three-core cables.

Single-core means that there is only one conductor in an insulating layer, and if it is to be used in a single-phase lighting line, two conductors need to be laid in parallel.

Twin cores are two conductors in one insulating layer, and only one is used to lay them if they are to be used in single-phase lighting lines. (Wires are divided into multiple strands and single strands, and soft cores and hard cores.) Select according to the conditions of use and the power used).

The main difference between single-core and multi-core is the flexibility of the wire. In essence, there is no good question between the two, but the environment of use is different, for example, if you want to use the pipe wiring in the family room, it is obviously better to use a single core, because the single core has a certain strength, the threading is convenient, and the joint connection is simple. However, there should be multiple turns for the line, and there are many bends in a line, so it is obviously better to use multi-core, because the flexibility of multi-core is good, and it can be bent better without breaking; However, the multi-core wire has the problem that the connector is easy to contact poorly and heat, so the connector should be handled well when using.

They are different: large power consumption, single strands buried in the wall, small power consumption, often change positions, active power sockets, multi-strands (the cost of a single strand is higher than that of multi-strands, and the power consumption is very small, and multi-strands can also be used for hanging and shed decorative lights) Single-strand lines are easy to break, can not be frequently held, and activities are not easy to use multi-strands, good toughness, and often active platter power supply.

Single-strand copper wire should be used.

Single-strand copper A single strand of copper wire carries a larger current than a multi-strand copper wire. Single-strand copper wire is generally used for installation.

Differences: the larger the cross-sectional area, the smaller the resistance value, the larger the rated current, the thicker the wire, the higher the cost, the same cross-sectional area, the performance difference between single and multi-strand wires:

1.Skin Effect Due to the skin effect, the equivalent resistance of multi-strand wires at high frequencies is less than that of single-strand conductors, and high-frequency transmission can only use multi-strand wires, the thinner the better.

2.Manufacturing cost The cost of multi-strand wire is higher than that of single-strand wire, so it is more often used in some occasions where it does not need to be moved, such as power leads inside buildings.

3.Ease of use There is no doubt that multi-strand wires are easier to bend and have good adaptability, and all home appliance power cords use multi-strand wires, due to the influence of metal fatigue, single-strand wires are easy to break after long-term bending.

For copper wire of the same cross-section, the current carrying capacity of multiple strands is greater than that of a single strand, and the electrician is correct.

The single strand has a reliable and long life, and the multi-strand is easy to thread.

After many years, due to surface oxidation, the resistance increases, and the joint is prone to problems.

It is false that the multi-strand current carrying capacity is larger, and the wage price is different from place to place and the process requirements are different, and the difference is very large.

Single strands are good, mainly for the resistance to oxidation and corrosion.

The decoration foreman explained the difference between single strand and multi-strand wires, as well as the advantages and disadvantages.

Answer the high cost performance of a single stock. A single strand wire is somewhat stiffer than a stranded wire and consists of a thick wire, while a double strand is made up of multiple filaments, the former is hard (BV) and the latter is soft (BVR). The single strand is relatively hard, the wiring is inconvenient, and the contact is not easy to break, but it is easy to break and burn in the case of damage, and the heat is relatively large, and it is cheaper.

Under normal circumstances, with the same square wire cross-sectional area, the single-strand wire is more durable, and it will not be easy to oxidize, and the resistance of a single strand is smaller than that of multi-strand wire, and the heat generated is small, and the possibility of accidents such as some flammable accidents will be small, and the safety factor is relatively high.

When purchasing, it is determined that there must be CCC certification mark on the wire, and the wire and cable products are national compulsory safety certification products, and all manufacturers must obtain the certification of the China Electrical Products Certification Committee"ccc"Certified, obtained"ccc"Certification marks, on the certificate of conformity or on the product"ccc"Certification mark. The more famous ones are Hongyan, Erguo Marking Line, etc.

Extended Materials. Because the multi-strand wire is a flexible wire, it will be much more convenient in construction, and it is easy to thread, and the conductivity of the multi-strand wire will be better than that of a single strand under the same cross-sectional area, and because it is composed of multiple copper wires, there will be a certain gap between the wires, so as to facilitate heat dissipation; However, it is higher than a single strand, and it is easy to be oxidized over time.

Pay attention to safety, it must be a single strand, good heat dissipation, low resistance value, and good stability, so household decoration uses a single strand;

The occasion of multi-strand is different, mainly soft wire, industrial equipment installation is more, too hard single strand is not good to install and has to use multi-strand soft wire.

1. The national standard specification stipulates that a single strand of plastic copper wire should be used for home decoration, and of course, the lamp head can use a multi-strand soft wire (also called sheath wire).

2. Under normal circumstances, the cross-sectional area of the wire of the same square. The conductivity of multi-strand flexible wire is weaker than that of single-strand plastic copper wire.

3. Relatively comparatively, the thin line in the multi-strand soft wire is prone to short circuit in the concealed engineering (dark line), and the heat is too large and it is easy to cause accidents such as heating and combustion. The resistance of a single strand of plastic copper wire is smaller than that of a multi-strand flexible wire, and the resistance is small, and the heat generated is less, and the heat is less likely to cause accidents such as combustion, and the relative safety is higher.

4. Compared with single-strand plastic copper wire, multi-strand flexible wire is not easy to handle perfectly at the joint winding and welding, and it is also prone to accidents.

5. If the multi-strand soft wire is used in home decoration, the only advantage is that it is used at the live wire, which is more convenient.

6. Home decoration is cost-effective, and the cost performance of a single strand plastic copper wire is higher than that of a multi-strand flexible wire. If you don't consider the cost, you can choose double-layer insulation and multi-core, plus special treatment process is the best.
