An electrical transformer is a metal casing containing two coils of copper wire (primary and secondary), wound around a magnetic core. It only operates on alternating current (AC). It is used to modify the voltage (and current) of alternating current without changing its frequency. A transformer makes it possible to adapt the voltage at each stage of the electrical network to transport, distribute and use electricity efficiently and safely.
The manufacturing of a low-voltage electrical transformer is a complex process involving several critical steps that may vary depending on the complexity and requirements of the transformer. Each step must be carried out with care to ensure the quality and reliability of the final electrical transformer. Here is a general list of the steps to follow to manufacture a low-voltage electrical transformer :
Design: The first step consists of designing the electrical transformer based on customer requirements, industry standards and manufacturing considerations. This step may include material selection, core design, electrical specification calculations, etc.
Component Manufacturing: After the design phase, it is time to manufacture the transformer components. This may include core manufacturing, winding the coils, cutting the laminations, manufacturing the supports, etc.
Assembly: Once the components are manufactured, it is time to assemble them. This step may include securing the windings to the cores, connecting the wires, installing the supports, etc.
Insulation: After assembly, the components must be insulated to ensure protection against electrical arcs and discharges. This step may include the application of insulating varnish, the installation of insulating tape, etc.
Quality Testing: After insulation, it is time to test the quality of the electrical transformer. This step may include resistance tests, leakage current tests, voltage tests, short-circuit current tests, etc.
Final Assembly: If the electrical transformer is intended to be used in a casing or panel, it is time to mount it in its final location.
Packaging and Shipping: The final step consists of packaging the electrical transformer and shipping it to the customer.
VARAT offers you a wide range of single-phase transformers:
We specialize in the design and manufacturing of three-phase power electrical transformers which are classified as separation transformers according to the standard (IEC 96.1) IEC 6/558-1 IEC61558-2-4 up to 5KVA, and the IEC 61558-2-4 standard.
Our transformers are designed to provide safe and efficient power supply for a variety of industrial, commercial and residential applications.
Our three-phase transformers are manufactured using high-quality materials such as pure copper and laminated iron cores to ensure optimal performance. They are also subjected to rigorous testing to ensure they meet the highest safety and quality standards.
