Introduction to 1kW 3 Phase Dry Type Transformer
The 1kW 3 Phase Dry Type Transformer is a low-power electrical device with a compact design specifically focused on safe voltage transfer in three-phase power systems. This product is commonly applied in industrial control systems, with considerations for fire safety, low maintenance, and protection of the environment being a top priority.
Unlike oil-immersed power transformers, the three phase dry type transformer has an air and/or solid insulation material which does not pose any risk of oil leaks and is hence suitable for indoor and restricted areas.
What Is a 1kW Three Phase Dry Type Transformer_?
A 1kW three-phase dry-type transformer is employed to step up and/or step down the voltage of a balanced three-phase power electrical network.
⚠️ In practice, the power is typically expressed as 1kVA, since transformer capacity is dictated by the apparent power value. Depending on the power factor of the load, the actual power developed will vary.

Suports three-phase motors and equipment
FAQ
What is a “dry type transformer”?
For instance, a dry-type transformer utilizes air or solid insulation, which is much safer in case of a fire.
Can a 1kW dry type transformer be installed indoors?
Yes. There are dry type transformers suited for indoor and restricted space installation.
How long is the life of a dry type transformer?
Commonly 20 to 30 years with proper installation and maintenance.
Is Overload Protection Required?
Yes. External protection devices like circuit breakers or fuses should always be used.
Is a power rating of 1 kW sufficient for an industrial?
It is used in control circuits, auxiliaries, or low-load applications rather than heavy power drives.
Conclusion
The 1kW 3 Phase Dry Type Transformer is an energy-efficient, safe, and eco-friendly alternative for the latest power management needs of three-phase systems. The dry-type, oil-free model has a compact design and adheres to global standards that make it the perfect choice for the latest industrial control panels and green.
