Induction Heater for Dismounting of Transformers

A transformer is an electrical device that is used to transfer electrical energy from one circuit to another through the principle of electromagnetic induction. It is typically composed of two coils of wire wound around a common iron core. Transformers are widely used in power distribution networks to increase or decrease the voltage of electrical power, allowing it to be transmitted more efficiently over long distances. Transformers are also used in a variety of other applications, including electronic equipment, industrial machinery, and transportation systems. They play a critical role in ensuring the safe and efficient operation of many different types of electrical systems.

When it comes to the dismounting of transformers, an induction heater is often used. An induction heater is a device that uses electromagnetic induction to generate heat in a metal object. It works by inducing electrical currents in the metal, which causes it to heat up due to the resistance of the material. The role of the induction heater in dismounting transformers is to heat the metal components of the transformer, such as the core and the winding, to a temperature that will allow them to be easily separated. This is necessary because transformers are typically assembled with tight tolerances, and the components can become stuck together due to corrosion or other factors over time. By using an induction heater to heat the metal components, the transformer can be disassembled without damaging the parts or requiring excessive force. 

GM Industries offers Transformer induction heaters in various kilovolt-amperes, ranging from 40 KVA to 150 KVA that helps to ensure that the transformer can be repaired or recycled efficiently and effectively, which is critical for the proper management of electrical equipment and resources.

Features of Induction Heater for Dismounting of Transformers

The features of an induction heater used for dismounting transformers may vary depending on the specific model. However, some common features that are typically found in these types of devices include:

Power output

  • The power output of an induction heater is a crucial factor in its effectiveness for dismounting transformers. The power output can range from a few kilowatts to several hundred kilowatts, depending on the size and complexity of the transformer being dismounted.

Customizable Coils

  •  The induction heater comes with interchangeable or customizable coils that can be adjusted to fit the specific size and shape of the transformer being dismounted. This allows for a more precise and efficient heating process, reducing the risk of damage to the transformer or the induction heater.

Control System

  •  An induction heater used for dismounting transformers have a user-friendly control system that allows for precise temperature control and monitoring. This may include digital displays for temperature, power output, and frequency, as well as programmable settings for specific heating profiles.

Cooling System

  •  An induction heater generates a significant amount of heat, and a robust cooling system is necessary to ensure safe and reliable operation. The cooling system may include air or water-cooled components, as well as built-in safety features to prevent overheating or damage to the equipment.

Safety Features

Induction heaters for dismounting transformers have built-in safety features such as overcurrent protection, short-circuit protection, and temperature monitoring to prevent damage to the transformer or the induction heater itself.


Overall, the features of an induction heater for dismounting transformers should be designed to provide efficient and safe heating, precise temperature control, and easy operation.

Advantages of Using Induction Heater for Dismounting of Transformers

There are several advantages to using an induction heater for dismounting transformers, including:

Precision Heating

Induction heaters allow for precise and localized heating of specific areas of the transformer, which reduces the risk of damage to the transformer or other components.

Efficient Heating

Induction heaters are highly efficient, converting most of the input energy into heat. This reduces energy consumption and operating costs, as well as minimizing the carbon footprint.

Time Savings

Induction heaters can heat metal components quickly and evenly, reducing the time required for disassembly and repair of transformers. This increases productivity and reduces downtime, which is especially important in industrial and commercial settings.


Induction heaters are designed with safety in mind, with built-in safety features to prevent overheating, short-circuiting, or other hazards. They also eliminate the need for open flames or other heat sources that can be dangerous or damaging to the environment.

Easy Operation

Induction heaters are easy to operate, with user-friendly controls and programmable settings that allow for precise temperature control and monitoring.


Induction heaters can be used to dismount a wide range of transformers, including those with complex shapes or configurations.
