Transformer 1070 O Aluminium Foils Strips For Transformers Winding Edges Options

Many people have the trouble of transformer 1070 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.

1070 O Aluminium Foils Strips For Transformers Winding: The Ultimate Guide

1070 O aluminium strip is a kind of transformer aluminum foil, which is widely used in various types of transformers.

The advantages of 1070 O aluminium foil are: low density, high conductivity and soft texture. 1070 O aluminium foil has a conductivity of up to 61%, the density is small, 2.7 g/cm3, which can reduce the weight of the transformer and reduce the size of the transformer manufacturing.

We can produce any thickness and width of 1070 aluminum strips according to your requirements.

What are 1070 O aluminium foils strips for transformers winding?

Aluminium strips 1070 O for transformers winding have many features like low density, high conductivity and thermal conductivity, good corrosion resistance, good plasticity, easy to coatings and other advantages.

Aluminium strips for electrical transformers is mainly used in the production of various types of transformers, the most popular is the production of dry type transformers winding.

Dry type transformer is a kind of transformer without oil immersion cooling method. It has a lot of advantages such as safety, reliability and environmental protection. So in recent years it has been widely used.

In addition to 1070 O aluminium foils for transformers winding, HZW can also produces 1060 aluminum strip for transformer winding and 1050 aluminum foil for transformer winding.

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.
