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.

aluminium enameled wire

1. Compared with the copper enameled wire, enameled aluminum wire is easier to winding, also there is asolid oxide film on the surface of enameled aluminum wire, which make it has a good insulating effect, a long life ;


2. Due to the good insulating effect of aluminum film layer, it's heat-resistant temperature can be 20 degrees higher than the copper wire;

3. The greatest benefit of using aluminum is that it is 1 / 3 lighter than copper which significantly lower the production costs, second it can attach to the solids easily, and third it can also reduce the freight and transportation during the operation.

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.

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.

fiberglass wrapped enameled wire 180

Product Name : Fiberglass Wrapped Enamelled Wire

Introduction：Fiberglass wrapped enamelled wire is the premium copper or aluminum conductor to be enamelled, then to be wrapped with fiberglass. Then it is impregnated in compatible insualting coatings of thermal class, baked to make a whole between fiberglass, insulating coating and conductor. There are four thermal classes of 130、155、180、200. The product is widely applied in generators、electrical machines、electromotors and other similar electrical instruments.

Standard：GB/T7672—2008

Aluminum Winding Wire

Aluminum winding wire is one of the main varieties of the winding wire. Zhengzhou LP Industry Co., Ltd can provide enameled aluminum winding wire which is composed of a conductor and an insulating layer.

Bare wire soften after annealing, and then several pain, finally bake. But it is difficult to produce that meet the standard requirements, but also to meet customer requirements. It is subject to raw material quality, process parameters, production equipment, environment and other factors. Therefore, the quality characteristics of enameled aluminum wire and enameled copper wire does not the same. But they are equipped with mechanical properties, chemical properties, electrical properties, thermal properties of the four properties.

How to Measure Enamel Wire Gauge

   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.
