Single Phase Transformer

Single Phase Transformer


Tunisie Transformateurs is the only Tunisian company who obtained Canadian production technology of single-phase transformers canadian circular type. It has been produced since 2002. It’s an immersed mineral oil cylindrical shape type which allows pole installation until a power of 3x210KVA= 630KVA.

Product Specification

Production specification covers requirements for both :
– Standard or classic on pole without integrated protection
– CSP (completely self-protected) and conventional type transformers
CSP transformers include attached primary arrester , primary fuse and appropriate secondary over-load and short circuit protection . For conventional transformers, shall be included.

Conception Features

Our transformers are designed in accordance with the latest revisions of AINSI & IEC standards.
The core of magnetic circuits are of the oval and are winding sheet.
This design reduces the load losses & increases its resistance to electromechanical shocks.

Test laboratory & Quality Conrol

Our laboratory equipments are calibrated by the Metrology of DEFNAT with its national and international accreditation which meet STEG requirements , IEC 76 standards, individual and types test.


Single-phase electrical transformers, or “transformers” as they are known for short, are electrical devices designed to transfer electrical energy from one circuit to another by magnetic coupling.

Single-phase electrical transformers are used to convert one voltage level to another or to adapt one load to another. They are commonly used in uninterruptible power supplies (UPS).


A single-phase electrical transformer is a type of electrical transformer by which one voltage is converted into another voltage, but with the same relative power.

Unlike the standard three-phase transformer, a single-phase transformer has only one winding which performs the primary and secondary functions (as opposed to two or three windings in three-phase transformers).

This means that from maximum load to zero load of the transformer, there are fewer turns in the primary winding than in the secondary winding.
