The thickness tolerance is ±0.02 mm, the width tolerance is ±0.1mm, the diagonal difference is less than 1mm and the surface quality is good.

The 1350 O Aluminium Foils Strips For Transformers Winding Edges Options

Many people have the trouble of transformer 1350 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.

1350 O Aluminium Foil For Transformer Winding: The Complete Guide

In order to avoid the problems that might be caused by inferior or faulty 1350 O aluminium foil for transformer winding, consumers are encouraged to only buy from reputable merchants.

There are several different brands of 1350 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 1350 O Aluminium Foil For Transformer Winding?

1350 O aluminium foil is the aluminum foil with an aluminum content of not less than 99.35%, and the same as the 1350 aluminum alloy, it is the most commonly used material in the aluminum foil industry.

The main alloying elements of 1350 aluminum foil are Fe and Si, so it also belongs to 1 series Al-Fe-Si aluminum alloy.

1350 O aluminium foil is widely used in high frequency transformers and inductors because of its good conductivity, shielding performance and soft texture. It can also be used in power capacitors, power transformers and other electrical equipment.

The common states of 1350 O aluminium foil are: O state (annealed state), H12, H14, H16, H18 and so on. The thickness ranges from 0.016mm to 0.2mm.

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 1350 O aluminum foil strip?

The 1350 O aluminum foil strip is a common material in the transformer winding, but why is it used?

The 1350 aluminum foil strip produced by our company is a kind of aluminum product with high current conduction, which can fully meet the requirements of large current and high frequency characteristics in the field of transformer.

1350 aluminum foil strip for transformer winding has high elongation, tensile strength, fully able to meet the special processing requirements of high tension winding.

1350 aluminum foil strip for transformer winding is a deformed aluminum product after continuous stamping. Its strength is 10% higher than that of 1 series pure aluminum, and it has good electrical conductivity. It is the best material for transformer winding.

What are the advantages of using 1350 O aluminium foil for transformers winding?

The aluminum foil is a good conductor of electricity. In comparison with copper and nickel, the conductivity of aluminum foil is second only to silver. Among the current 500KV UHV transformers, more than 90% are wound with aluminum foils.

The specific gravity of aluminum foil is only one-third of copper and nickel. In the case of ensuring the same mechanical strength, the weight of 1350 O aluminum foil can be reduced by two-thirds compared with copper and nickel materials. This helps reduce the load on high-voltage towers and reduce transportation costs.

1350 O aluminium foil has many advantages. Therefore, it is widely used for transformers winding in power transmission and distribution systems. Compared with other types of transformer foil, 1350 O aluminium foil transformer has great advantages, such as:

1. Higher tensile strength and elongation of transformer aluminum foil, which can meet the needs of bending and stretching during windings in high-frequency transformers.

2. Higher resistivity of transformer aluminum foil, which is a good conductor for electric current, but does not have much effect on magnetic flux.

3. Higher density and specific gravity of transformer aluminum foil, which can effectively prevent the magnetic field from leaking outwards and reduce the loss of electromagnetic induction intensity.

4. The electrical conductivity of 1350 O transformer aluminum foil is higher than that of electrolytic aluminum, which can improve the efficiency of power generation and transmission.

How to deal with 1350 O aluminium foil for transformers winding packaging?

The packaging for transformer 1350 aluminum foils strips is mainly about wooden pallet and wooden box.

1350 aluminum foil length of each roll should be same, packaging mark should have clear and complete information.
