Magnet wire tyes

Like other wire, magnet wire is classified by diameter (AWG number, SWG or millimeters) or area (square millimeters), temperature class, and insulation class.

Breakdown voltage depends on the thickness of the covering, which can be of 3 types: Grade 1, Grade 2 and Grade 3. Higher grades have thicker insulation and thus higher breakdown voltages.

The temperature class indicates the temperature of the wire at which it has a 20,000 hour service life. At lower temperatures the service life of the wire is longer (about a factor of 2 for every 10 °C lower temperature). Common temperature classes are 105 °C, 130 °C, 155 °C, 180 °C and 220 °C.

THE RISE OF A NEW LABEL--“MADE IN CHINA”(二)

The problem of most of the Chinese companies is not limited technologies, or unskilled workers, the biggest problem which explain sometimes the fact that the quality is not good enough is really strict bill of specifications. Western companies want large quantities in very short delays at really low prices. The thing is that today, to respect the short delays of the Western companies, some Chinese companies rather deliver products with a lower quality by respecting the delays and low prices.

China have been during thousands of years for Western countries the manufacturer of products really appreciated as silk, spices, jewelry, cashmere, carried on the silk road in direction to Europe, which were synonyms of a high quality and a know-how inimitable.

Today Chinese companies want to go back to this time when hallmarks of Chinese products were synonym of high quality. The Chinese government is investing in some companies as Xiaomij and Lenovo which are breaking the rules by creative innovating products making forget for the buyers the “Made in China” label.

With a massive workforce and a government engaging his companies to innovation, Chinese companies should see their reputation raised in the next few years. As an encouraging observation, today we found 6 companies based in China on Forbes’ Most Innovative Companies List.

Today, Zhengzhou LP Industry Co., Ltd also wants to set things right for their “Made in China” label, providing excellent services, products of a great quality at attractive prices and secured packaging to their customers to insure the security of their orders. Zhengzhou LP Industry Co., Ltd has many certifications proving the quality of their products and is ready to receive potential customers to their factories to show them the respect of the certification restrictions.

THE RISE OF A NEW LABEL--“MADE IN CHINA”(一)

“Made in China” is probably what you find the most since decades on all the products you are buying during your shopping sessions. Your outfit is probably manufactured by some Chinese people thought.

But let’s come back on the reputation of the “Made in China” seen by the Western countries. When you hear the mention “Made in China”, you probably suppose products of bad quality, bad conditions of the workers and reminds you some scandals which happened at some times.

We can’t say that these facts don’t exist, but we can moderate what you’re thinking.

Chinese workers are not today working for $1 per day, in wretched conditions. In fact, in 2013, the average cost of labor in China is only the average of half the cost in the US and increase each year on an average of 20%, and could reach 60% in 2015 according to the Boston Consulting Group.

China is today too expensive for most of the western companies of the textile industry which desire to reduce their cost of production. Western countries rather relocate their production in India, Philippines and Bangladesh which are looking like Chine 15 years before.

Trend of Magnet Wires’ Development(二)

Light Weight

Electrical products according to design requirements, lightweight methods in some less demanding usage are light weight material selection rather than small diameter lightweight, such as some less demanding micro-motors, voice coil speakers, artificial pacemaker , microwave oven transformers and other products. These products use enamelled aluminum wire and enamelled copper clad aluminum wire to process. Enamelled aluminum wire and enamelled copper clad aluminum wire has the features of light weight and low cost compared to enameled copper wire. At the same time, there are processing difficulties, poor welding , tensile strength and small shortcomings. Only a microwave oven transformer, it is considerable according to China's annual production of 10 million sets of calculations.

Self-bonding

Special performance of self-bonding enameled wire can express without skeleton coil winding or avoid dipping. Self-bonding enameled wires are mainly used for TV deflection coil speaker, buzzer, micro-motors, transformers and other electronic applications. Depending on the portfolio at the end finish, the selection of material and different heat levels, self-bonding enameled wire can satisfy different occasions. The variety in terms of acoustic and color TV deflection amount is considerable.

In order to meet the challenges brought by the large international market, Zhengzhou LP Industry CO., Ltd insists on high quality and technical innovation strategy. Main products: enameled copper wire, enameled aluminum wire, enameled copper clad aluminum wire, paper covered wire , kapton copper wire , oxidative aluminum and so on.

Trend of Magnet Wires’ Development(一)

Magnet wires are widely used facilities in the industrial manufacturing. And in order to meet the increasingly high demand, the development of magnet wire becomes increasingly fine. As more and more different needs, different types of magnet wires have also come out.


Fine Diameter

Due to the use of enameled miniaturization, such as camcorders, electronic watches and clocks, miniature relays, automotive, electronic instruments, washing machines, televisions and other electrical products. Their components are moving in the direction of a smaller diameter. For example, TV ignition coil that is integrated with a line output fly back transformer primary wire around the law when using sub-tank insulation, use the specifications to φ0.06 ~ 0.08 mm and thick insulation. But they are now replaced by flat design around the law after the inter layer insulation wound structure, diameter to φ0.03 ~ 0.04 mm, and thin paint.

How to Test Electric Motor Windings Instructions

1.Remove all power from the motor and isolate the circuit. Tag the circuit breaker to prevent accidental restoration of power. Open motor housing to access windings.


2.Clean the windings and motor interior with shop air and inspect for any damage. Check winding insulation for cracks or brittleness.


3.Connect the probes to the ohmmeter and set the meter to a midrange setting. Touch the two leads together and make sure that the meter indicates continuity, or zero ohms.


4.Consult the motor schematic or a diagram of the motor's windings and use the meter to measure the resistance of the windings. Each winding leg should have some small resistance reading. The meter should not show an "open" or a "short" when a winding leg is measured.


5.Use the schematic and take readings of all of the windings. Write down each measurement and make comparisons when measurements are complete.

what is magnet wire

Magnet wire is used in the manufacture of electrical products in coils or windings of insulated wire. Also known as winding wire. Magnet Wire must meet the requirements of multiple use and workmanship. The former includes the shape, size, can short and long-term work at high temperatures, and in some cases subjected to centrifugal forces of strong vibration and high speed, tolerability corona and breakdown under high voltage, chemical resistance under the special atmosphere corrosion; the latter included wound and embedded line subjected to tensile, bending and wear requirements, as well as dipping and drying process of swelling, erosion and so on.

Magnet wire can its basic components, conductive wire core and an electrically insulating layer classification. Usually divided into wire, wrapping wire, paint surrounding the envelope and the inorganic insulating wire insulation materials and manufacturing methods based on an electrically insulating layer being used.
