Name: China Cast Resin Type Transformer Manufacturers Suppliers Factory - Wholesale Service - GNEE Electric
Brand: GNEE Electric
SKU: 275632096

A cast resin transformer is a type of dry-type transformer where the windings are encased in a cast resin, typically epoxy resin. This encapsulation provides protection against environmental factors like moisture, dust, and corrosion, making them suitable for various applications, including those with high humidity or fire risks. They are known for their reliability, high overload capacity, and low maintenance requirements.

Cast resin type transformer is a type of dry-type transformer made by casting epoxy resin. Its core structure consists of coils and resin castings, which do not require oil immersion and are suitable for indoor installation.

Product Introduction

Resin cast transformer is a widely used type of transformer in electrical engineering and has many alternative names, including mold cast transformer and resin glue cast transformer.This transformer adopts the epoxy resin casting process to form an insulating structure. The high-voltage winding is vacuum-cast from aluminum foil and insulating foil, while the low-voltage winding is wound with a single layer of aluminum foil or copper foil. The entire series is made of flame-retardant and self-extinguishing materials and has passed multiple national fire protection certifications, featuring E2 environmental grade, C2 climate grade and F1 fire resistance grade. The equipment supports the installation of cooling fans to achieve 50% continuous overload operation.

The structural form and cooling of

The dry type cast resin

Installation environment: When installing, at least 1-2 meters of ventilation space should be reserved to avoid damp or high-temperature environments (temperature range -20℃ to 40℃, humidity 40% to 60%). Keep away from corrosive gases and heat sources (such as heating components of injection molding machines). ‌

Voltage and Load: The input voltage must match the rated value (allowing ±10% fluctuation), and the output connection should select the appropriate cross-sectional area of the wire according to the load power to ensure the correct phase sequence. During operation, it is necessary to monitor whether the voltage/current fluctuates abnormally to avoid overload .
