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:

1, high-frequency transformers, general transformer;

2, the inductor, the electromagnetic coil;

3, motor, household electrical comprising various micro-motors and compressors;

4, the sound coils, special magnet wire;

5, monitor deflection coils;

6, degaussing coils;

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.
