Three Points When Use Copper Clad Aluminum Wire(2)

2, The copper clad aluminum wire and enameled copper clad aluminum wire can be not used in many categories practically. But the fact that many companies which make transformers are used. It is very worried. There are two concerns about the copper clad aluminum wires’ use.One concerns is temperature rise, because its cross-section copper resistivity ratio is higher than copper wire.The other concern is that aluminum wire is so easily to be oxidizable that conductor resistance will further increase.

3, The most worrying is the contact between copper and aluminum in copper clad aluminum wire.The reliability of copper and aluminum contact which metallurgy industry sector often said can not be proven true.And whether copper and aluminum contact can be tested in the process of reliability in the process of thermal expansion and contraction.

Three Points When Use Copper Clad Aluminum Wire(1)

Three Points When Use Copper Clad Aluminum Wire

The Application of Copper Clad Aluminum Wire:

Notes of the use of copper clad aluminum wire:

1, Copper clad aluminum wire as the signal transmission is possible, but now as a power transmission, it is easy to go wrong, and the life expectancy of their goods will be greatly reduced. In fact,if people note the wire section of oxidation maintenance, to ensure a useful link copper and aluminum,when the use of copper clad aluminum wire, the copper clad aluminum wire can be of long-term use.

Magnet Wire Specification Ranges

Although our magnet wires are aesthetically pleasing—with red, green, clear, and blue colors available—our magnet wires are also made to withstand a range of temperatures, from 105° C to 240° C.

To accommodate multiple applications, we feature solderable, bondable, and high-temperature insulation types, as well as single, heavy, triple, and quad enamel builds. 

We also offer several winding wire types, including Rubadue single, double, and triple.

round rectangular enameled copper wire

Enameled Copper Wires are available in various dimensions covering as per customers requirements. Our quality, reliability and efforts to give satisfaction have placed us in a unique position within the winding industry.

ROUND COPPER WIRE

For application in telecommunication and electro industry, enameled wire 0,02 up to 5,00 mm diameter, temperature class105 up to 200° C is manufactured. Enamelled wire insulation is on the basis of polyurethane, polyvinyl formal, polyester, polyesteramide and polyesterimide.

Special products are manufactured of enamelled wire of small diameters as follows: cables, flexible conductors and braids.

RECTANGULAR COPPER ENAMELLED WIRE

For manufacturing of transformators, electromotors and electrical counters windings, shaped enamelled wire is manufactured with the biggest section 40 mm2, temperature class 120° C, enamel insulated on the basis of polyvinyl formal and polyvinyl acetate.

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.

Advantage of NOMEX Paper Wrapped Wire

NOMEX paper covered wire’s electrical, chemical and mechanical properties are extremely high, and it’s elasticity, flexibility, anti-tearing, moisture resistance and resistance to wear are very good. Moreover it has the acid and alkali corrosion. And it is not easily destroyed by insects, fungus as well as streptomyces. It has the compatibility with all kinds of varnish, adhesive, transformer liquid, lubricant, and coolant. Meanwhile, NOMEX paper has strong thermal resistance. Even if the temperature reaches 220℃, the insulation property is the same. Transformer with NOMEX paper wrapper wire can bring client a lot of economic, environmental and safe benefits.

Lower Cost, smaller Size, Lighter Weight

The temperature of transformer with NOMEX insulation can rise up to 180℃. Because the transformer needs fewer wires and ferrite cores and then it has smaller size and lighter weight, thus capital construction can be reduced. It is easy to install the transformer. Smaller ferrite core means reducing no-load loss.

Reliability Improvement

With NOMEX paper wrapped wire, the electrical specification and the mechanical property are outstanding in the transformer’s entire service life. NOMEX paper and there is no crack. NOMEX insulation paper is not sensitive to temperature, dust and thus improve the reliability of transformer.

Increase of Reserve Capacity

NOMEX paper covered wire’s thermal resistance is high, so even though the temperature reaches 220℃, the insulation property maintains the same. Rank C of 220℃ takes the place of Rank of 180℃during the design of transformer, so it may deal with the urgent load situation and the dilatancy unexpectedly and can make backup plan.

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.
