Our company ELVIN manufactures various types of custom transformers – we produce single-phase, two-phase and other types of transformers.
Transformers are not only responsible for the conversion of electricity but are also used for safety. What if you need a transformer for your device, which must meet different parameters than the usual ones? Have a transformer made to meet exactly your own individual requirements.
What are transformers?
Transformers work on the principle of electromagnetic induction and are used to convert the electrical energy of one voltage into the electrical energy of another. If the goal is to galvanically separate two circuits, in that case also to convert the same voltage.
A transformer is a non-rotating electrical machine that changes the voltage ratios and current voltages in a circuit while the frequency does not change. It only works with AC or DC voltage, a voltage that can change over time.
The main task of the transformer is to reduce, increase or maintain the voltage, which is very important due to the following advantages:
- reducing investment costs
- savings over long-distance transmission
- safety in electricity consumption
There are two basic groups of transformers – toroidal and electronic. Electrical transformers are lighter and their task is to direct one-way current. The toroidal ones have a much higher weight and alternating current passes through them.
Based on what material they are made of, we divide transformers from:
- transformer plate
- ferrite core
- iron powder

Transformer production: What are they used for?
Transformers are used especially when we need a lower voltage than in the electrical circuitry for the correct operation of the electrical appliance. This can be seen, for example, in bathroom fans, which need a voltage lower than 230 V.
Transformers are also used in common adapters. The 230 V, a suitable voltage, which is proper for powering kitchen appliances, heating elements, power tools or lamps, is not suitable for radios, computers, printers, or televisions. They need much lower voltage to function.
Therefore, it is necessary to adapt the supply voltage to the needs of a specific appliance. The voltage is first reduced by the transformer and then the current is rectified. The voltage from the socket is also transformed to a lower voltage by chargers for individual devices, such as mobile phones, laptops, etc.
Transformers also find their use in the transmission of electrical signals, if the signal is to be transmitted from one circuit to another. This is used with traffic lights for sound effects.
They are also used for the distribution of electricity over long distances, such as powering villages and housing estates. Block transformers are used in power stations.
Transformers boast a relatively simple form and the absence of mechanically moving parts. They are characterized by extremely long life and low maintenance costs. Of course, only if the transformer is used in accordance with its purpose and technical specification.
Production of custom transformers
In some cases, you need a special electrical transformer that meets all the individual requirements of a special device. Then it is appropriate to have a custom-made transformer made.
Generally, functional transformers may not meet your requirements. You may need a specific voltage or size to fit in the case. For such occasions, our company manufactures various types of custom transformers.
Advantages of custom transformers
- great variability of dimensions and shapes
- low and high voltage transformers
- without having to adjust anything
- piece and serial orders
- possibility to choose: power, voltage, wiring diagram, noise, number of taps, number of windings, transformer dimensions, color
- selection of equipment with protective devices
The quality of custom-made transformers
The quality of produces transformers is influenced by several factors. The basis is a thorough control of product quality and sufficient technical equipment of control workplaces. Thanks to this, the required level of quality of individual transformers is ensured, regardless of whether they are made to measure or belong to classic transformers with given parameters.
It is essential that the control mechanisms follow strict guidelines when selecting individual components. Likewise, the control devices themselves must meet a high level of quality.
What types of transformers are manufactured?
Transformers, like most components designed to regulate current properties, are used in both single-phase and three-phase versions. While the three-phase configuration allows the voltage to be directed individually to several branches, in the case of a single-phase it is much easier.
The transformer is connected via connectors or outputs directly above the branch or circuit. When installing the transformer, it is necessary to orientate on the basis of the required secondary voltage.
In the industrial field, large transformers are applied as a tool that enables the unification of the input network. In practice, this means that it is possible to adapt the production equipment to the specific operating conditions of the equipment, even if they come from different regions and have different standard voltages.
Smaller transformers, with the size and appearance of a separate component, could be connected to an electrical circuit and allow the formation of branches with different voltage values.
