Enameled wire industry

The AWG tables are for a single, solid and round conductor. The AWG of a stranded wire is determined by the cross-sectional area of the equivalent solid conductor. Because there are also small gaps between the strands, a stranded wire will always have a slightly larger overall diameter than a solid wire with the same AWG.

Principle: Water molecule (HHO) decomposes water into oxygen and hydrogen through electrolysis. Hydrogen is combustible. Oxygen supports combustion. These two gases are ignited to form a hydrogen-oxygen flame. In layman’s terms, “water turns into fire”

Fiberglass Covered Insulated rectangular aluminum wire is in accordance with customer requirements in aluminum conductor uniform whole winding package 1-2 layers of alkali-free fiberglass, with the necessary temperature resistance index and compatible adhesive paint dipping and baking process, glass fiber and conductor between bonded into a whole.

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.

Flat enameled wire is a type of enameled wire. It is a winding wire made of oxygen-free copper rods or electrical aluminum rods that are drawn, extruded or rolled by a certain specification die, and then coated with insulating paint for many times. The thickness is from 0.025mm To 2mm, the width is generally less than 5mm, and its aspect ratio ranges from 2:1 to 50:1. Flat enameled wire has a wide range of uses, especially in the windings of various electrical equipment such as telecommunication equipment, transformers, motors and generators.

The main advantages of fiberglass covered wire are:
1. The quality factor Q value is large;
2. Because it is twisted by multiple enameled wire bundles, it has good flexibility and can reduce the skin effect;
3. Because it is composed of polyurethane enameled wire, the dielectric loss angle is small, and it has direct solderability.
The disadvantage is: poor moisture resistance.

Enameled wires are widely used in industrial production, household appliances and other industries. The main properties and uses of various enameled wires are as follows: Various machines, communication equipment, meters, relays, small transformers, etc.

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.

Generally speaking, UL certified enameled wire needs to do four tests:
Thermal Aging Test (Full Thermal Aging Test or One Temperature Thermal Aging Test)
Dielectric Strength Test
Elongation and Heat Shock Test
Infrared Analysis – IR

In the long-term thermal aging test, three or more temperature points are usually selected for accelerated aging, commonly known as “three-point aging”.

The samples for the aging test are stranded enameled wire pairs. The production of the stranded pairs should meet the requirements of ASTM D2307 or NEMA 1000 standards, including the weight to be applied when making the stranded pairs, the number of twisted turns, the effective length of the stranded area, and The length of the two ends of the twisted pair, etc. When making a twisted pair, the required force and the number of twist turns will vary depending on the diameter of the wire. The effective length of the stranded area has nothing to do with the wire diameter, the effective length is 121¡À6 mm, and the two ends are at least 50 mm long. At least 10 twisted pairs per temperature point and mounted on twisted pair racks for high temperature aging test.

Compared with general round wires, flat enameled wires have the following advantages:
Higher floor area ratio and better use of space: The high conductor density enables coils and components of the same size to achieve higher efficiency, save materials and reduce costs.

The infrared spectrum analysis test is based on the standard UL746A, which only confirms the chemical composition of the paint film, establishes the infrared spectrum and retains it. After the enameled wire is certified, samples will be sampled for testing every year during the follow-up inspection service. The infrared spectrum made by the paint film on the sampled sample needs to be compared with the infrared spectrum established on the sample at the time of certification. The two infrared spectrums must be comparable. superior.

Water quality affects the production of lacquer wires?

The production water production water in the lacquered wire has a variety of uses, and like, the requirements for water quality are also different. Depending on the purpose of use, the water quality can be divided into: annealing furnace water seal water, equipment cooling water, lubricant manufacturing water, etc.

Glass-fiber covered aluminum magnet wire used to have weak coating strength (abrasion resistance, shock resistance, and flexibility). However, that disadvantage has been significantly improved recently by refining material selection and manufacturing methods. The demand for glass-fiber covered aluminum magnet wire is increasing as the wires have excellent uniformity and electrical properties under high temperatures and humidity.

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.

What is the first thing to make the enamel wire? And the manufacutring process of enameled wire is important, the extruding and baking. And the raw materials: copper conductor or aluminum conductor is enough for client’s requiremnets

Silver plated copper wire is manufacture with the combination of silver and copper and Silver Plated Copper Electrical Wire is manufactured using grade copper and silver; the industrial standards are always kept into the consideration.

The current enamel wire industry is relatively low due to the admission threshold, and therefore the production enterprises have more and more, and the market competition is constantly intensified, but in the high-end product field, there are not many companies that can enter, in the present, and future, The enamel wire business wants to achieve better development, and build brands and scale becomes more and more important.

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.

The selection criterion of the electromagnetic wire is not considered for resistance, as the problem of resistance and fever can be done by selecting the same cross-sectional wire, it is the main consideration of the thick wire or the thin wire is mainly considered Operability.

Electrical wiring to be run in conduit comes in individual strands, encased in insulation to protect the wire and insulate it from other wires and the conduit. Wires come in ither solid or stranded, depending on the wire size. Bare conductors are available for ground wires only. The insulation is made to take on some rather extreme conditions. Heat-, oil-, gasoline- and water-resistant coatings are all available to help your Insulated electric wire survive.

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.

The enamel wire is a wire having an insulating layer, which is a transformation of electromagnetic energy in a winding form, also known as a winding wire.

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 coated with insulating paint on the outside of the bare Aluminium wire, constitute the inside due to the effect of insulating varnish, between the two adjacent wire can bear 200 v ac voltage Q general insulation flow line surface light, soft, can work under the condition of 130 ¡æ continuous.In addition, enameled wire bending also requires 10 times, paint should not fall off, in order to meet the winding when won’t appear the quality problem.

7 type of enameled wire in accordance with insulation materials, list the thermal class, advatanges and application per type of enameled wire. Enameled wire types also can be divided into copper magnet wire and aluminum wire in accordance with conductor.
