A cast resin dry-type transformer (CRT) is a type of electrical transformer that uses solid epoxy resin insulation instead of oil or liquid coolant. It is designed for indoor and outdoor applications which offers high safety, low maintenance, and excellent resistance to moisture, dust, and pollutants.
A cast resin dry-type transformer is used in different commercial, industrial, and utility applications, as they come with various benefits. The advancements in this transformer have technologically made electrical devices efficient and compliant over the years.
Initially, these transformers were set up to be created in the city of Vadodara of Gujarat over 55 years ago. The company flourished as it expanded with experiments directed at the invention of new and better transformers.
F and H class insulation are primarily used for the primary and secondary windings.
Windings are made of copper or aluminium, depending on the current rating requirements.
Silicon steel is commonly used to ensure high permeability and minimal hysteresis loss.
Achieved with a leakage resistance of less than 2% to maintain design efficiency.
Depends on winding insulation integrity, which is affected by temperature rise due to overloading.
To minimize eddy current and core losses, leakage and winding resistance must be controlled.
Leads to overheating, which limits loading capacity. A fan-cooling system is added to dry-type transformers to mitigate this issue.
Selected based on the primary impulse level, contributing to the transformer's longevity.
Designed to withstand non-sinusoidal heat generation in the windings.
These transformers are primarily found in:
Used in remote forest locations.
Installed in city substations.
Essential for gas, oil, and chemical industries.
Operate in environmentally challenged areas.
Found in underground substations.
Support renewable energy generation sites.
Easy installation, low clearance
Strong overload support
Safe and eco-friendly
Reliable in moisture conditions
Cost-effective for fire protection
Short-circuit resistant
