In the production of dry type transformers in Europe, America, Japan, South Korea, etc., aluminium strips have been widely used to replace copper foil or copper wire to wind low-voltage and high-voltage coil winding. The advantages of aluminium strips for transformer have been recognized and experienced by the majority of users. The product manufactured by <strong>transformer aluminum strips suppliers</strong> are used as the conductor of high and low voltage coils, which meets the requirements of miniaturization, light weight, crack resistance and aging of dry type transformers, greatly improves the technical performance parameters of the product, and improves the service life to more than 40 years.</p>
<br><p>
If the copper wire is used to wind the high-voltage coil, which is bound to increase the dry volume and increase the loss. Moreover, the insulation reliability is lowered due to an increase in the voltage between the conductor layers. At the same time, due to the reduction of the electrostatic capacitance between the conductors, the ability of the high voltage coil to resist overvoltage is reduced, which affects the service life and operational safety of the dry type transformer. Because the price of aluminum is much cheaper than copper, and the density of aluminum is much smaller than that of copper, so the aluminum of the same section is much lighter than copper, but its conductivity is not much lower than copper, as long as the use of aluminum with a larger cross section, it can achieve the same or even lower power consumption than copper. The grade of <strong>aluminium strips for transformer</strong> are 1060, 1050, 1070, 1350, the temper is O(soft), the thickness is 0.2--3.0mm, the width is 20-1650mm. The surface is smooth and free of scratches, there are no burrs on the sides and can also have round edge.</p>

With the development of the economy, the amount of transformers has increased, and the demand for dry-type transformers has increased even more. Dry-type transformers have the following advantages over oil-type transformers, low cost, long life, good flame retardancy, high safety, low noise, low loss, small size, light weight, convenient installation and maintenance, and low frequency of inspection and maintenance, low local power efficiency, strong short-circuit resistance, strong lightning-impact resistance, strong overload capability and high reliability. The aluminum dry type transformer has good crack resistance, so <strong>transformer winding aluminum tape</strong> are widely used in dry type transformers.</p>
<br><p>
Shearing is the most critical part of <strong>transformer winding aluminum strip</strong> production, mainly because the transformer aluminum tape has higher requirements for edge burrs. Since the transformer aluminum strap is used to wind the transformer, it is necessary to prevent the burr from piercing the insulating layer and avoid the burr tip discharge. The actual shape of the edge of the aluminum strip after slitting is not an ideal rectangle. Therefore, the production of aluminum strip for transformers must be edge treated to remove shear burrs and chamfered or rounded edges. The commonly raw materials for processing transformer winding is 1060 aluminum temper O(soft) with round edge and without burr. The thickness is 0.10-3.0 mm, the surface of the <strong>transformer winding aluminum tape</strong> is without pot and oil.</p>

Aluminium strip is used as a conductor in dry-type transformers to wound on the core instead of copper winding. <strong>Aluminium strip for transformer</strong> winding is required with high conductivity, soft, smooth surface, no burr and high quality. According to the analysis, the chemical composition, hot rolling, cold rolling, shearing, heat treatment processes, internal organization, electrical conductivity, hardness and mechanical properties of materials will affect the application on transformer winding. In common, the aluminum strips alloys used in dry type transformers are 1050, 1060, 1070 and 1350, the temper is O which means soft, the thichness is 0.08-3.0mm and the width is 16-1500mm.</p>
<br><p>
When the aluminium strip is wound on the transformer core, the aluminum strip is tensioned to maintain a certain tension, and the transformer winding coil is wound smoothly and flatly. So the temper soft is usually used in the <strong>aluminum strips for transformer</strong> winding. To improve the quality of produced aluminium strips, the high-precision aluminum coil slitting unit is adopt, independent research and development of edge chamfering technology for high-precision round edge fillet processing.Thus, the <strong>aluminium strip for transformer</strong> produced by Haomei Aluminum is with round edge and without burr, which meet the requirements and welcomed by our customers, they are willing to have long term cooperation with our factory, and the monthly output of aluminum strips is up to 1000 tons in Haomei.</p>

Haomei provide high quality <strong>aluminium capping strip</strong>, the surface is degreased and clean, and has good deep-drawing performance, low ear-making rate, and excellent sealing, plasticity and corrosion resistance. The aluminum strip for caps material is widely used in the packaging of bottle caps and other fields such as alcohol, beverages, medical cap materials and cosmetics.<br><br></p>
<br><p>
Aluminum strip for bottle caps has alloy and temper of 3105, 8011, H14, H16, H18, the thickness is 0.2mm ~ 0.3mm, the width is 50mm ~ 1500mm, the roll inner diameter are 75mm, 152mm, 200mm, 205mm, 300mm, 350mm, 405mm, 500mm, 510mm. As the <strong>aluminum strip for caps</strong> materials has to go through the cap-making process when it is processed into formal bottle caps, this has new requirements for the base material of aluminum cap strip materials. Haomei have invested in technical research and development, after baking through the cap-making process, the stability of the aluminum strip becomes better and the strength is higher, and the existing processing technology is greatly improved, so that the performance indicators of aluminum strip for bottle cap materials reach a higher level. The 8011 <strong>aluminium capping strip</strong> material process must be completed through cold rolling-foil rolling annealing thickness-annealing-foil rolling finished product-stretch bending straightening-slitting and other processes. After the finished coil is produced, it must be cut and painted by a flattening machine, drying, multiple stamping, anti-counterfeiting marking and other processes to produce qualified bottle cap materials.</p>

Haomei <strong>aluminium flat strip</strong> has no trachoma, stomata and pinholes on the surface and has better flatness. As an aluminum strips manufacturer in China, Haomei has rich experience, we improve the processing efficiency and reduce the material cost. After the aluminum coil is stretched and bent, it can improve the flatness and play a role in leveling, this processing method is used to correct the aluminum strip with high surface flatness, improve uniformity and density, greatly improve the corrosion resistance of aluminum strips and the surface flatness.</p>
<br><br><br><p>
The quality requirement of aluminium strips product including the inherent metallurgical quality, surface quality, shape and flatness requirements are the highest, it requires optimized flatness and surface quality. Therefore, the drawing and leveling process plays a vital role in production. In order to improve the surface quality, flatness and straightening efficiency of <strong>aluminium strip</strong>, a new straightening process suitable for continuous production has been developed in recent years.</p>
<br><p>
The aluminium flat strip production line must have an advanced drawing and leveling (straightening) process, which can effectively eliminate the intermediate waves, edge waves, and chatter marks, herringbone mark and Camber brought during the rolling process. There are two commonly used levelers: pure stretch levelling and stretch bending. The latter is used more, but the former must be used when producing high-grade thin aluminum strips that require high straightness. The flattening machine often forms a continuous <strong>aluminium flat strip</strong> production line with the coating machine and the washing machine.</p>

<strong>Aluminium strip 5mm</strong> for transformer 6061 and 6063 has excellent interface characteristics, easy coating, high strength, good workability, and strong corrosion resistance. Usually, the aluminum strips with thickness over 3mm are called aluminum bus bar or aluminum flat bar. The common thickness range of aluminum busbar is 3mm-12mm. The common width range is 10mm-125mm. Classification: Right angle & rounded corner (commonly known as straight rounded edge).</p>
<br><br><br><p>
The connection of high-voltage power distribution devices in substations, as well as the connection of electrical equipment such as transformers and corresponding power distribution devices, mostly use rectangular or circular cross-section bare wires or stranded wires, which are collectively referred to as bus bars. The role of the bus is to collect, distribute and transmit electrical energy. Because the busbar is running, there is a huge amount of electric energy passing through it, and it bears a lot of heat and electromotive force effect when it is short-circuited. Therefore, the busbar material, cross-sectional shape and cross-sectional area must be reasonably selected to meet the requirements of safe and economic operation.</p>
<br><p>
Aluminum bus bar has good electrical conductivity, thermal conductivity, corrosion resistance, high mechanical strength, no low temperature brittleness, easy welding, and easy pressure processing. <strong>Aluminium strip 5mm</strong> is currently widely used in switch cabinet bus bars and lead wires of generators and transformers. Rectangular conductors have a large surface area for heat dissipation. When used to transport large currents, multiple rectangular busbars are used in parallel.</p>
