Some notes to electromagnetic coil

Electromagnetic coil is a fine of components.Improper use can easily cause damage its electromagnetic coil. There has a great impact on the overall operation of the device. When we use,there are many places that need to pay attention. Here we are in the course of all of its points to note reminder for everyone:

1. When we use, it must sure that the voltage should never exceed the voltage index which coils can withstand, otherwise the solenoid would be burned, causing serious impact on the overall mechanical operation.

2. The thickness of the length of the solenoid coil are different and there is no absolute right perfect layout. People often choose according to their own needs.

3. If the unit is required to work long hours in factories, the temperature of working pressure of our electromagnetic coil temperature will rise. At this time, people should carry out protective measures according to their specific circumstances.

4. In our time, we can make that the solenoid coil is processed according to the conditions. Do not make the electromagnetic coil performance in disorder.

Only when we ensure the safety of the use and reasonable diligence to protect and ensure, the use of magnet wire will be under normal conditions of use. Our electromagnetic coil can create greater efficiency for long-term services .

Modified Polyester-imide enameled wire

Modified Polyester-imide is produced by insulating the conductor with a single coat of a solder-strippable modified polyester resin. Physical properties are adequate for most coil applications. More severe winding requirements such as in-slot stator windings are not recommended without thorough evaluation. This film may be readily stripped from the conductor by immersing in an 850° - 950°F solder pot; care must be exercised in preventing the film from over-cutting due to poor immersion techniques.

Awg magnet wire

Magnet wire insulating films use (in order of increasing temperature range) polyurethane, polyamide, polyester, polyeseter-polyimide, polyamide-polyimide (or amide-imide), and polyimide. Polyimide insulated magnet wire is capable of operation at up to 250°C. The insulation of thicer square or rectangular magnet wire is often augmented by wrapping it with a high-temperature polyimide or fiberglass tape, and completed windings are often vacuum impregnated with an insulating varnish to improve insulation strength and long-term reliability of the winding.

An Important Standard of Enameled Wire

Zhengzhou LP Industry Co., Ltd has been engaged in the production of enameled wire for many years. So it has accumulated a wealth of industry experience. Here let us take a look at some criterias of enameled wire.

An Important criteria is the appearance of enameled round wire or flat wire as follows:

Enameled round wire:

When conductor nominal diameter d≤0.200mm, at a distance of three orientations of each of 1m, each measuring a diameter, according to three measured values, the mean value as the outside diameter.

When conductor nominal diameter d> 0.200mm, 1m apart on two orientations, each orientation along the magnet wire week average 3 times the outer diameter measurement, recorded six measured values, the mean value as the outside diameter.

Enameled flat wire:

Apart on each 100mm3 orientations wide and narrow sides of each measure scale 1, the average value of three measurement values ​​as wide and narrow sides of the shape scales.

Enameled Wire should be bright, uniform color, no particle without oxidation, scared shortcomings yin and yang side, no black mottled peeling paint, etc.. And the function of discharge line should be structured, tightly wound flat online disc, no pressure line which affect the appearance.

Correct production process of enameled wire

The quality of enameled wire depends although to a large extent depends on the objective circumstances paint, wire and other raw materials and machinery and equipment quality. It should do many thing that can produce high-quality enameled wire. It should take care of baking, annealing, speed and other issues in the operation and be aware of their mutual relations . At the same time, if people have not mastered technique, not do a good job of work and stop tour finishing work, the process does not improve health. Even if the objective conditions better, it do not produce high-quality enameled wire. So we must take care of enameled wire production process seriously in order to produce high-quality enameled wire products. Now let our Zhengzhou LP Industry Co., Ltd , a professional manufacturers to introduce the correct method of operation of enameled wire.

1, Paint charter before driving should be open fan to make the furnace air circulation to slow. Ignition temperature of the furnace and the catalytic domain with an electric preheating, the temperature of the catalytic zone reaches a predetermined catalyst.

2, The film should be measured once an hour. Before measuring, micrometer card correction keep zero.

3, Check all moving parts properly. Pay attention to put a spool of elastic to prevent rolling head, and drawing a fine break and diameter.

4, During enameled wire production operations, it should also pay attention to the explosion and fire problems, mainly inside the furnace fire phenomenon.

the model of enameled wire products

There are a lot of people who do not understand the model of enameled wire products in their daily work. They do not understand numbers and letters written on enameled wire . As a professional supplier of enameled wire, this news will introduce how to check the models of enameled wire.

In fact, the model comprise of the Chinese phonetic alphabet and Arabic numerals . It included the product's family code, insulation material code, etc.. After these series code, code of insulating material, film thickness, heat levels and other parts sequentially grouping together according to sequence, it will finished the rows of small print written above enameled wire products. Enameled wire products represent with models, specifications and standard number. In order to know more beneficial for your understanding , let us use a example to illustrate:

QZ-2 / 130L 1.00 GB / T 6109.7-2008 / IEC 60317-34: 1997

Chinese name: 130L grade polyester enamelled round copper wire

When it refers to equivalent standard number, GB can equal to IEC

Domestic sales can only write GB number. However export products may only write IEC number.

GB / T 6109.1 ~ 23-2008 a standard number corresponds to only one product.

Application of magnet wire coating products

Magnet wires and enameled wire with an insulating electrostatic powder coating is mainly applied in concentrated sulfuric acid treatment instead of the metal aluminum magnet wire on the insulating oxide film can also be applied on the insulating paint coating enameled. Usually the powder coating film thickness for a wire diameter of the round wires or width × thickness of more than 1.6mm, 1.6mm × 1.6mm above the flat line, the coating thickness above 40μm insulating coating, so for require a thin coating of the coating was also unable to apply. If you are using ultra-thin powder coating can also do a thickness of 20 to 40μm, but due to the difficulty of the cost of processing and coating of paint, can not promote a large number of applications. When the film thickness is too thick, the pliability of the performance of the coating film is decreased, does not apply to products on the metal wire bending angle is too large. Due to the limit of the film thickness is too thin metal wire is not suitable for using a powder coating process.

Powder coating magnet wire is mainly used in welding machine, electromagnet, dry-type transformers and other electrical products.
