A low tension transformer, known as an LT transformer, is an electrical device designed to reduce voltage from a higher level to a lower one, enabling it to be utilized for various applications. They are vital components of any electrical system because they ensure that energy is supplied at the appropriate voltage to energize homes, businesses, and industries.
Types of Low Tension Transformer
As low tension transformer suppliers in Sharjah, we have mentioned some types of it to specify requirements of the customers.
- Single-Phase Low Tension Transformer: This is the most common LT transformer, commonly used in residential and light commercial applications. It has two different windings: primary (high voltage) and secondary (low voltage), coiled around a common core. These transformers are simple, reliable, and economical, making them ideal for dropping the voltage for single-phase loads like lighting, appliances, and electronic equipment. They are commonly used to distribute power across buildings and also to supply power to particular devices.
- Three-Phase Low Tension Transformers: These transformers are applied in three-phase power systems. Here, both the primary and secondary windings are configured as a delta. This configuration provides high stability for voltage delivery and is usually applied in the industrial field in which stable delivery of voltage to motors and several machines is of prime importance. These transformers have no neutral point, so they are not used in applications where a neutral point is required. They are widely used for the distribution of power in industries and also for feeding three-phase loads with significant magnitude. The star-delta transformers further establish a phase difference between the voltages at the primary and the secondary side. This might be important in certain applications. These transformers are employed in distribution substations where they reduce the supply voltage to household and business consumers.
- Auto Low Tension Transformer: The difference between the two-winding conventional transformers which have two separate windings is that the autotransformers consist of a single winding with a tapped connection. This winding acts as the main and auxiliary winding. Autotransformers provide better size efficiency and weight performance than alternative two-winding transformers at equal power capacity levels. These transformers do not supply electrical insulation between primary and secondary circuits, so these devices present increased occupational risks in specific application environments. These devices serve voltage regulation operations and produce various voltage outputs and find utility when constraints exist regarding physical dimension and product weight.
- Isolation Low Tension Transformer: These devices contain technical characteristics that establish electrical separation between the primary sections and the secondary devices. The protective nature of this isolation shields equipment and personnel against both voltage spikes and surges together with ground faults. Isolation transformers have a 1:1 turns ratio; the output voltage equals the input voltage. These transformers operate in safety-critical systems alongside medical devices and numerous applications requiring electrical isolation for secure operation and operational excellence. Isolation transformers maintain special importance for shielded electronic devices to defend them from power line disruptions and electromagnetic interference.

Features of Low Tension Transformer:
We design and supply multiple kinds of LT transformers which are known for their quality and features. Some features of it are given as below:
- Voltage Conversion: Its primary function is to reduce the voltage from a higher level, such as distribution voltage, to a lower level suitable for end-use appliances, for example, 120V or 240V.
- Isolation: They provide electrical isolation between the primary (high voltage) and secondary (low voltage) circuits, thus enhancing safety.
- Diverse Configurations: Available in both single-phase and three-phase configurations to suit various power supply needs.
- Various Cooling Techniques: Smaller LT transformers generally utilize air cooling, whereas larger units might employ oil cooling for enhanced heat dissipation.
- Core Material and Winding: Laminated silicon steel is frequently utilized for the core to reduce energy losses. Their conductors, made of copper or aluminum, are used for the windings.
