World Class
Distribution Transformers

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.

Design Structure

Insulation Type

F and H class insulation are primarily used for the primary and secondary windings.

Lifespan

Depends on winding insulation integrity, which is affected by temperature rise due to overloading.

Core Material

Silicon steel is commonly used to ensure high permeability and minimal hysteresis loss.

Regulation

Achieved with a leakage resistance of less than 2% to maintain design efficiency.

Winding Material

Windings are made of copper or aluminium, depending on the current rating requirements.

Losses

To minimize eddy current and core losses, leakage and winding resistance must be controlled.

Overload

Leads to overheating, which limits loading capacity. A fan-cooling system is added to dry-type transformers to mitigate this issue.

Insulation Level

Selected based on the primary impulse level, contributing to the transformer's longevity.

K-Factor

Designed to withstand non-sinusoidal heat generation in the windings.
