Cast Resin Dry Type Transformer (CRT) Types
For voltage conversion, our cast resin MV transformers are safer and more efficient. They lower the medium voltage to the low voltage to provide power for the final equipment.
The resin cast dry type transformer has a optimized cooling ducts and an air self-cooling design. They dissipate heat quickly and work with a long term operation.
If you have requirement for a specific voltage levels, tell us. We can customize flexiably to meet your needs.
The 3-phase cast resin dry type transformer is designed specially for commercial and industrial sites. Following are some of their key features.
1. Work stable with high efficiency
2. Each phase is vacuum-cast in epoxy resin. This makes it have strong insulation and excellent moisture resistance.
3. It has optimized cooling design and smart tempreture control system
4. It is clean, fire-resistant and requires low maintenance.
Advantages of epoxy cast resin dry type transformer
Becoming a dry type cast resin transformer manufacturer trusted by worldwide clients has many reasons. The main reason is that OMEK’s products have incomparable advantages.
The windings are epoxy resin, with a whole encapsulation. Fire and exposion risks are reduced.
The strong structure is formed in the process of the resin curing the windings. Super sealing performance.
It uses high grade silicon steel and amorphous alloy materials to achieve low losses and energy saving.
Its enclosure protection ranges from IP20 to IP54. Dust, water and moisture can’t come in.
It’s oil free. No risk of pollution from oil leaking. Lower noise compared with the oil type transformer.
Vacuum pouring reduces partial discharge. OMEK makes it with a design life of more than 30 years.
It is nearly maintenance free, compared with the oil type. That saves your time and costs.

Applications
Our successful case in South Africa
In 2021, we delivered the SC9 model 1000 kVA cast resin transformer to our South African customer. The customer gave us clear specification requirements. Before production, our team made more than ten modifications to the drawings. After the customer’s use, through our tracking and monitoring, the no-load loss of the SC9 type product has decreased by 25% compared with the national standard, the load loss has decreased by 11%, and the noise level has decreased by 11 decibels. These data are even lower than that of similar products from Siemens and ABB.

A cast resin transformer is also a dry type transformer. Its windings are encapsulated in solid epoxy resin. This design provides excellent insulation, fire resistance, and moisture protection. It is ideal for indoor and sensitive environments. Such as data centers, hospitals, and commercial buildings. No oil is used, it is clean and low-maintenance.
A cast resin transformer is a type of dry type transformer. All dry type transformers don’t use oil. Cast resin types use solid epoxy resin to encapsulate the windings. It provides higher mechanical strength and fire safety. There’re other dry type transformers, such as VPI transformers. This transformer uses a different insulation method, but it has a similar function as the cast resin transformer.
Cast Resin (Dry Type): Uses solid insulation. No oil, fire-safe, low maintenance, suitable for indoor and sensitive applications.
Oil Transformer: Uses oil for insulation and cooling. It needs regular maintenance. It has higher risk of fire or leaks. If often used in outdoor or high-power applications.
Cast resin transformers are safer and cleaner. They are especially for spaces where need more safety.
Cast Resin Transformer: Windings are fully cast in epoxy, self-extinguishing, moisture-resistant, very safe for indoor use.
VPI Transformer (Vacuum Pressure Impregnation): Windings are impregnated with resin under vacuum, offering good insulation but slightly less mechanical rigidity compared to cast resin.
Both are dry type, but cast resin is often preferred for high-safety or sensitive installations.
