Environmental Safety: Cast resin transformers are environmentally safe as they do not contain any oil. This makes them suitable for use in areas where the risk of environmental pollution is high.
Low Flammability: Cast resin transformers have a low flammability rate, making them safe to use in areas where fire risk is high.
Longevity: Cast resin transformers have a longer life span than traditional oil-filled transformers. This is because they are less prone to rust and corrosion over time.
Low Maintenance: Cast resin transformers require very little maintenance compared to traditional oil-filled transformers. This saves money in the long run.
Temperature Resistance: Cast resin transformers can withstand high temperatures without risk of oil leaking or catching fire. They are therefore ideal for use in areas with extreme weather conditions.

Types of Cast Resin Type Transformer
Cast Resin
These transformers also referred to as CRTs, are enclosed in epoxy coating and are suitable for use in areas with a lot of moisture. This is done to stop moisture from getting within the windings, that would impair the functioning of the transformer.
Transformer Impregnated by Vacuum Pressure
High voltage is used when a vacuum pressure impregnated transformer functions, and its minimally flammable insulation is formed of foils and strips. The winding is formed of disks connected in series or parallel to accommodate larger voltages.


The dry-type transformer insulates its windings and core without the need for fluids. Instead, a sealed cast epoxy resin that contains the windings and core is used.
In places with significant levels of moisture, cast resin dry-type transformers are used. It’s a result of the epoxy glue that surrounds its principal and secondary windings (non-hygroscopic). The winding can’t get wet because of the encapsulation.
Power ranges from 25 KVA up to 12,500 KVA, and the insulation class is F. (90oC Temp. Rise).
Low loss and low partial discharge. As a result, efficiency is excellent. It poses no risk of a fire hazard since non-flammable winding insulation is used. It can therefore be installed indoors.
Applications of Cast Resin Type Transformer
Renewable Energy Systems: Renewable energy systems like solar and wind power facilities heavily depend on cast resin transformers to both increase and lower voltage levels.
Industrial Manufacturing: The industrial manufacturing sector that includes automotive and steel and cement as well as chemical infrastructure uses cast resin transformers to distribute their power requirements.
Marine and Offshore Applications: The compact structure of cast resin transformers makes them suitable for marine and offshore platforms and ships as well as submarines since they resist saltwater corrosion and withstand vibration exposure.
Data Centres: Uninterrupted power supply together with efficient energy management remains essential for data centres operations. These facilities choose cast resin transformers because they deliver efficient operation combined with low losses and safe performance in fire conditions.
Mining Operations: Mining operations depend on cast resin transformers for powering the equipment and machinery at both underground and above ground mining sites. The transformers have sturdy design features that protect them from moisture effects and both dust damage as well as explosive gas exposure which makes them work well in mining sites with tough operating conditions.
Hospitals and Healthcare Facilities: In hospitals, where uninterrupted power is critical for life-saving equipment, cast resin transformers are the preferred choice. These transformers maintain safety and reliability because they are both maintenance-free and fire-resistant and operate with low noise levels which produce an environment that supports patient care needs.
