Magnet wire is an insulated wire used to make coils or windings in electrical products. Also called winding wire. Magnet wires must meet the requirements of a variety of uses and manufacturing processes. The former includes its shape, size, ability to work at high temperatures for short and long periods of time, as well as withstanding strong vibration and centrifugal force at high speeds in some occasions, resistance to corona and breakdown under high voltage, and resistance to chemicals in special atmospheres Corrosion, etc.; the latter includes the requirements of stretching, bending and abrasion during winding and embedding, as well as swelling and erosion during dipping and drying.

Traverse refers to the material used for wire and cable, and also refers to wire in industry. It is generally made of copper or aluminum, and it is also made of silver wire (good electrical conductivity and thermal conductivity), which is used to reduce electrical current or conduct heat.

1060 Transformer Aluminum Strip Product Description:
060 transformer aluminum belt is a special purpose aluminum belt product produced for transformers. It uses high-purity aluminum substrate and aluminum deep-processed products formed by slitting aluminum coils with an aluminum content of more than 99.60%. The raw material of transformer aluminum strip is high-purity aluminum, which is rolled into thin sheet aluminum coils of different thicknesses and widths by a cold rolling mill, and then longitudinally slitted into aluminum strips of different widths by a slitting machine according to the application. It is an important raw material in industry. The main processing equipment of 1060 transformer aluminum strip is slitting unit, which can be divided into required length and width according to needs. Usually the transformer aluminum strip is slit according to the actual needs of the user, which can reduce waste, reduce processing procedures (without cutting), and save raw material costs.

NOMEX paper is a synthetic aromatic amide polymer insulating paper, which has high mechanical properties, flexibility and good electrical properties, and can maintain its characteristics at higher temperatures, and is widely used in power generation Machines, transformers, electrical equipment, electromechanical and household appliances.

The coil is wound around an insulating tube by a wire, and the wires are insulated from each other. The insulating tube can be hollow, or it can contain an iron core or a magnetic powder core. The inductance of the coil is represented by L, and the units are Henry (H), millihenry (mH), microhenry (¦ÌH), 1H=10^3mH=10^6¦ÌH.

PET film is a more comprehensive packaging film. It has good transparency and luster; it has good air tightness and fragrance retention; it has medium moisture resistance, and its moisture permeability decreases at low temperatures. PET film has excellent mechanical properties, and its toughness is the best among all thermoplastics. Its tensile strength and impact strength are much higher than ordinary films; it has good stiffness and stable dimensions, and is suitable for secondary processing such as printing and paper bags. . PET film also has excellent heat resistance, cold resistance and good chemical resistance and oil resistance. However, it is not resistant to strong alkalis; it is easy to be charged with static electricity, and there is no proper anti-static method. Therefore, attention should be paid when packing powdery articles.

Inductors are components that can convert electrical energy into magnetic energy and store it. The structure of the inductor is similar to that of a transformer, but it has only one winding. The inductor has a certain inductance, it only hinders the change of current. If the inductor is in a state where no current is flowing, it will try to block the current from flowing through it when the circuit is on; if the inductor is in a state where current is flowing, it will try to maintain the current when the circuit is off. Inductors are also called chokes, reactors, and dynamic reactors.

A layer of non-conductive materials, such as resin, plastic, silicone rubber, PVC, etc., is evenly and hermetically wrapped around the wire to form an insulating layer to prevent the conductor from contacting the outside and causing leakage, short circuit, electric shock and other accidents. The wire is called insulation wire.

Cable paper, also known as insulating paper, is paper with insulating properties and dust loss functions. Cable paper is also called cable insulation paper. An insulating paper for high-voltage power cables, control cables and signal cables. Specially used in magnet wire factory, transformer factory, transformer factory, reactor factory

The wire drawing metal processing technology can form fine lines on the surface of the metal material, which makes the metal more textured, and is used as a decoration by users and is well-loved. In the production process, the drawing lubricating fluid is indispensable in the drawing metal processing technology. It is widely used in the lubrication of the middle drawing, small drawing and micro drawing of enameled copper wire. So how to choose this kind of drawing fluid?

Electromagnetic wires used to make motor windings can basically be divided into two categories: enameled wires and wound wires, in addition to inorganic insulated electromagnetic wires. Improve the electrical and mechanical properties of the magnet wire, improve its solvent resistance, heat resistance, and reduce the thickness of the insulation, which can greatly increase the slot full rate of the motor. The slot full rate is the ratio of the total cross-section of the conductor in a slot of the motor to the cross-sectional area of ??the slot, or the filling factor of the slot. This value is of great significance for reducing the volume and weight of the motor.

Enameled wire production water also has many uses, and similarly, the requirements for water quality are also different. According to the water quality requirements of the purpose of use, it can be divided into: annealing furnace sealing water, equipment cooling water, lubricant manufacturing water, etc.

Enameled wire is widely used in our production and life. The paint it uses is a kind of paint that can produce a good insulating layer between the wires in the winding.
Enameled wire is made on the basis of copper wire. Simply put, enameled wire is a layer of insulator on the copper wire, usually plastic. Enameled wire paint is a kind of outer layer of bare copper wire, alloy wire and glass wire covered wire of various wire diameters to improve and stabilize the performance of enameled wire. It has high mechanical strength, resistance to Freon refrigerant, good compatibility with impregnating paint, and can meet the requirements of heat resistance, impact resistance, oil resistance, etc.

Winding wires used in electrical equipment are usually called magnetic wires. In other words, “magnetic wires are used to exchange electrical energy and magnetic energy.” Magnetic wire is roughly divided into enameled wire (insulation coated) and coated wire (fiber/film insulation) and their combinations. The two types of magnetic wires and their performance are very different. ASTM (American Society for Testing and Materials) B193, no more than 0.017241 ohm (square millimeter/meter), the film or coating should meet the latest version of ANSI, ASTM or NEMA applicable standards, and modify the specified resin. The modified resin is Chemically changed resin, or containing one or more additives to retain the basic chemical characteristics of the original resin to enhance certain performance or application characteristics, the coated conductor needs to meet all the required test requirements of the appropriate NEMA standard (UL certification project) .

Enameled wire is a main type of winding wire. It is composed of a conductor and an insulating layer. After the bare wire is softened by annealing, it is painted and baked many times.

General purpose enameled wire (ordinary wire): Mainly used for winding wires in general motors, electrical appliances, instruments, transformers, etc., such as polyester enameled wire and modified polyester enameled wire.

1. Mechanical functions: including elongation, rebound angle, softness and adhesion, paint scraping, tensile strength and other items.
(1) Elongation reflects the plastic degeneration of the material and is used to check the ductility of the enameled wire.
(2) The rebound angle, the softness reflects the elastic deformation of the material, and is used to check the softness of the enameled wire.
¢ÇThe durability of the paint film includes winding and stretching, that is, the promised tensile deformation of the paint film without cracking when the conductor is stretched and deformed.
(4) The adhesion of the paint film includes snap-off and peeling. First, check the adhesion of the paint film to the conductor.
(5) The scratch resistance test of the paint film reflects the strength of the paint film against mechanical scratches.

The conductive properties of pure metal materials are ranked. Among them, the material with the best conductivity is silver (Ag), followed by copper (Cu), after copper, it is gold (Au), and then aluminum (Al). Analyzed from the application level, silver and gold are precious metals and cannot be used in large quantities when the unit price is too high. Copper is the best choice for moderate price and good performance, and it is the main force used in the current industry. It is widely used in electrical related industries, such as enameled coils used in motors, whose internal conductors are made of copper. Although aluminum is the cheapest material among them, the difference in its electrical conductivity is an unacceptable conductor material in applications where high efficiency is the premise.

Insulating paint is composed of three parts of paint base (natural or synthetic resin, asphalt, drying oil, fiber paper and its composites, etc.), solvent or diluent, and auxiliary materials (drier, pigment, emulsifier, antifungal agent, etc.) . According to the purpose, it can be divided into three types: dipping paint, covering paint and adhesive paint.

Use a hydrogen-oxygen flame welding machine to weld the coil lead wires of electronic devices such as motors, motors, and transformers.

working principle:
Water is composed of hydrogen and oxygen. In a specific electrolytic cell, water can be decomposed into hydrogen ions and hydroxide ions. The hydrogen ions move to the cathode to generate hydrogen gas, and the hydroxide ions move to the anode to generate oxygen. Hydrogen is a fuel. Oxygen can be used to support combustion. It can be ignited by a specific hydrogen-oxygen flame gun to form a hydrogen-oxygen flame, which can quickly weld the enameled wire.

The biggest difference between enameled aluminum wire and enameled copper wire for single-phase induction motors is also caused by the poor conductivity of aluminum. Therefore, the wire diameter of enameled copper wire has to be reduced to 0.12. The same motor specifications as enameled aluminum wire can be reached by about mm. On the contrary, if the single-phase induction motor that originally used enameled copper wire is changed to enameled aluminum wire, the wire diameter must be somewhat larger. To increase, it can reach the specifications required by the original motor. Therefore, the motor will need more space to accommodate the increased wire diameter, but this more space is often the most difficult to provide among the motors.

Although the quality of enameled wire depends to a large extent on the quality of raw materials such as paint and wires and the objective conditions of machinery and equipment, if you do not take a series of problems such as baking, annealing, and speed, and understand their interrelationships. , Do not master the operation technology, do not seriously do the touring work, stop and tidy up the work, do not do well in the process and hygiene, even if the objective conditions are good, it will not be able to produce high-quality enameled wire. Therefore, the decisive factor for good enameled wire is people’s sense of responsibility for work.

Inductive sensors have outstanding advantages such as simple structure, fast dynamic response, and easy non-contact measurement. They are especially suitable for acids, alkalis, chlorides, organic solvents, liquid CO2, ammonia, PVC powder, ash, oil and water. Liquid level measurement such as interface is currently widely used in metallurgy, petroleum, chemical, coal, cement, food and other industries.

There are some differences between polyester enameled wire and polyurethane enameled wire in terms of use occasions and performance:
Polyester enameled wire, composed of copper conductor and polyester resin, has a thermal class of 130, and after modification, the thermal class of the enameled wire is 155. It has good mechanical strength, paint film adhesion, excellent electrical, scratch resistance, chemical resistance, thermal stability and solvent resistance. It is widely used in various motors, electrical appliances, meters, telecommunications equipment and home appliances; the weakness of this product is poor thermal shock resistance and low moisture resistance.

Polyurethane enameled wire, thermal grade is 130,155,180. The biggest feature is that it has direct solderability, good high frequency resistance, easy coloring, and good moisture resistance. It is widely used in electronic appliances, precision instruments, telecommunications, and meters. The weakness of this product is that the mechanical strength is slightly poor, and the heat resistance is not high. , And the flexibility and adhesion of the production of large-size wires are poor, so the specifications of the product are mostly small and medium-sized wires.
