Transformer 1050 O Aluminium Foils Strips For Transformers Winding Edges Options
Many people have the trouble of transformer 1050 aluminum foils strips edge.
In the actual operation process, due to the influence of steel strip hardness and unloading speed, it is difficult to effectively control the edge of the transformer aluminum foil strip.
However, after our technical personnel have studied for a long time, we have found a solution to this problem.
The solution is: in order to make the edge of aluminum foil uniform, it is necessary to reduce the rolling pressure as much as possible and improve the surface quality of steel strip (for surface defect repair and removal).
This requires that in addition to adjusting the equipment parameters in strict accordance with the requirements of process technical conditions, but also according to different casting billets (casting thickness), different rolling mills and rolling mills (working roll sets) and different batches of materials.
The corresponding design and adjustment should be carried out for relevant process parameters.
Transformer 1050 O Aluminium Foils Strips For Transformers Winding: The Ultimate Guide
In order to avoid the problems that might be caused by inferior or faulty 1050 O aluminium foils strips for transformers winding, consumers are encouraged to only buy from reputable merchants.
There are several different brands of 1050 O aluminium foil that are offered for sale on the market.
This makes it easier for buyers to find exactly what they want in comparison to other similar items.
If you are the beginner of this field, here is the right place you go.
What are 1050 O aluminium foils strips for transformers winding?
1050 O aluminium foils strips for transformers winding is widely used in the production of transformers.
With the continuous development of power industry, the requirements for transformer are also getting higher and higher.
The development of large volume and low loss transformer will promote the continuous improvement of product performance and quality, thereby promoting the continuous improvement of supporting materials.
In recent years, in order to meet the needs of global’s large-scale distribution transformers, large-capacity power transformers, ultra-high voltage power transmission and transformation projects, World’s transformer manufacturers have successively developed high-quality 1050 O aluminium foils strips for transformers winding with a thickness of 0.08 mm or less and a width of 10 mm or less through several technological reforms.
At present, most China domestic strip manufacturers produce 0.25mm thick aluminum foil strip coil with a width of 1250mm and a thickness tolerance below +/-5μm.
Common transformer winding problems
Transformers are often one of the most common elements we find in electrical equipment. They are used to transfer electrical power, typically to increase or decrease the voltage.
However, they can also be susceptible to several problems, which can lead to their degradation or even failure. These winding problems require maintenance and repair work, which usually involves a costly process and downtime.
Common transformer winding problems:
One of the most common types of winding problem is the formation of shorts between turns. This kind of short is found at different locations in a transformer winding, caused by imperfection during the manufacturing process, improper storage and handling, or excessive mechanical stress.
Shorts between turns may happen over the entire length of a coil end or along its length. They can be classified according to their location as either hot-spot shorts (between adjacent layers) or cold-spot shorts (between adjacent turns).
Another type of winding problem is insulation faults caused by partial discharges that occur in a transformer’s winding insulation system. They occur when part of the insulation breaks down under electric stress. In turn, it produces ionization channels that trigger localized current pulses that dissipate energy and produce gases inside the transformer’s winding system.
Why does transformer use 1050 O aluminum foil strip?
The 1050 O aluminum foil strip is a common material in the transformer winding, but why is it used?
- The chemical composition of 1050 O aluminum foil strip is Al99.5%, which has high conductivity and low price, and has become an indispensable material for power transformers.
- The transformer 1050 aluminum foil can be used not only for low voltage dry type transformers, but also for oil immersed transformers and high voltage transformers.
