How many square wires should be allocated to 9 kilowatt electrical equipment?

A wire is a wire that transmits electrical energy. It is divided into bare wire, magnet wire and insulated wire. Bare wires have no insulating layer, including copper, aluminum flat wires, overhead stranded wires, and various profiles (such as profile wires, busbars, copper bars, aluminum bars, etc.). It is mainly used for outdoor overhead and indoor busbars and switch boxes.

Magnet wire is an insulated wire that generates a magnetic field when energized or induces an electric current in a magnetic field. It is mainly used for motor and transformer coils and other related electromagnetic equipment. Its conductor is mainly copper wire, which should have a thin insulation layer and good electrical and mechanical properties, as well as heat, moisture, solvent resistance and other properties.

Wire and cable products are mainly divided into five categories:

1. Bare wires and bare conductor products.

The main characteristics of this type of products are: pure conductor metal, no insulation and sheath layer, such as steel core aluminum stranded wire, copper-aluminum busbar, electric locomotive line, etc.; The processing technology is mainly pressure processing, such as smelting, calendering, drawing, stranding, pressing and stranding, etc.; The products are mainly used in suburbs, rural areas, user mainlines, switch cabinets, etc.

2. Power cables.

The main characteristics of this type of product are: extruding (winding) the insulating layer outside the conductor, such as overhead insulated cables, or several cores stranded (corresponding to the phase wire, neutral wire and ground wire of the power system), such as overhead insulated cables with more than two cores, or adding a sheath layer, such as plastic rubber sheathed wires and cables. The main process technologies are drawing, stranding, insulation extrusion (wrapping), cable formation, armoring, sheath extrusion, etc., and the different process combinations of various products are different.

3. Wires and cables for electrical equipment.

The main characteristics of this type of products are: a wide variety of specifications, a wide range of applications, the use of voltage in 1kV and below more, in the face of special occasions continue to derive new products, such as fire-resistant cables, flame retardant cables, low-smoke halogen-free low-smoke and low-halogen cables, termite-proof, anti-rat cables, oil-resistant, cold-resistant, temperature-resistant, wear-resistant cables, medical, agricultural mining cables, thin-walled wires, etc.

4. Communication cables and optical fibers (brief introduction).

With the rapid development of the communication industry in the past 20 years, the products have also developed at an astonishing speed. From the simple telegraph cable in the past, it has developed into thousands of pairs of telephone cables, coaxial cables, optical cables, data cables, and even combined communication cables.

The structural size of this type of product is usually small and uniform, and the manufacturing accuracy is high.

5. Magnet wire (winding wire).

It is mainly used for various motors, instruments, etc.

1. If it is a household use, it is a 220V single-phase electricity, and the current is about 45A when 9kW is fully opened, and it will definitely not reach this value normally, so it is enough to use a 6 square wire.

2. If it is a three-phase 380V, use 4 square copper wires, and if it is a single-phase 220V, use 10 square copper wires.

Commonly used copper core wire: 6A square power.

1 square current 6 amps wire diameter 1320 watts.

Square current 10 amps wire diameter 1980 watts.

Square current 15 amps wire diameter 3300 watts.

4 square current 24 amps wire diameter 5280 watts.

6 square current 36 amps wire diameter 7920 watts.

10 square current 60 amps wire diameter 13200 watts.

The current calculation is actually 6 8A, and now it is all calculated in 6 A.

9 kW with 6 square lines。In general, it is necessary to use the wire of the 6-level base briefing party, but this is not a certain value, and it needs to be determined according to the material and voltage value of the wire. If the 9 kilowatt device is connected to a single line voltage of 220 volts, then the maximum current value is 40 amps, but because the actual use, the circuit will be damaged, so it cannot reach 40 amps, if the aluminum wire is used, 10 square wires are needed, and if copper wires are selected, 6 square copper wires are required.

The meaning of kilowattskW stands for kilowatt and is a unit of measurement for electrical power in physics.

1kw is 1000w, which represents a thousand times the basic unit.

watts, 1kWh represents one kilowatt of electricity, that is, the amount of electrical power of one kilowatt of electrical appliances working for one hour. The definition of electrical power per watt is the amount of electrical power per second per unit time, and the electrical power p power w per unit time s. And the work done by 1 watt of electricity in 1 second is equal to 1 joule.

That is, 1 joule and 1 watt second.

9 kilowatt electrical equipment should be equipped with 6 square wires, wires refer to the wires that transmit electric energy, magnet wires are insulated wires that generate magnetic fields or induce currents in the magnetic field after being energized, it is mainly used for motor and collapse hail voltage coils and other related electromagnetic equipment.

The wire is composed of one or several soft wires, and the outer layer is covered with a light and soft sheath; The cable consists of one or several insulated wrapped wires, which are surrounded by a rigid outer layer of metal or rubber with a burning sail. Cables and wires are generally composed of three parts: core, insulating skin and protective sheath.

Hello dear, glad to answer for your answer: 1If it is a potato and a household, it is a 220V single-phase electricity, and the current is about 45A when 9kw is fully open, and it will definitely not reach this value normally, so it is enough to use a 6 square wire.

2. If it is a three-phase 380V, use 4 square copper wires, if it is a single-phase 220V, you need to use 10 square copper wires, adjust according to the actual situation, I hope mine will be helpful to you.

Kilowatt electrical appliances with a few square wires Hello dear, is to use square millimeters of wire, oh if "two-phase electricity" actually refers to 220 volts single-phase electricity, then 6400 220 = 29 amps, it is recommended to use 6 square millimeters of copper wire. If "two-phase electricity" actually means that the rated voltage of the electrical appliance is 380 volts and two phase wires need to be connected, then 6400 380 = 17 ampere, it is recommended to use 4 square millimeters of copper wire. If "two-phase electricity" actually refers to the rated voltage of 220 volts of electrical appliances, the use of three-phase 4-wire power supply lines of "two wires" and "one zero", each phase is divided into 3200 watts, then:

3200 2200 = amps, can be <> with square millimeters of copper wire

Hope mine is helpful to you, thank you and have a great day!
