Product Description

A 20kVA to 5400kVA Three-phase Dry-type Rectifier Transformer is a high-performance, air-cooled power conversion solution designed for environments where safety, reliability, and power quality are paramount. By using advanced epoxy resin casting or VPI (Vacuum Pressure Impregnation) insulation systems, it eliminates the fire risk and potential leakage associated with liquid-filled units. This transformer is specifically designed to provide a stable, isolated AC source for rectifier systems, converting incoming AC power into the precise DC output required for a wide range of industrial processes.

Key Technical Features

• Enhanced Safety and Environmental Friendliness:As a dry-type transformer, it contains no flammable insulating oil, significantly reducing the fire hazard. This makes it ideal for installation indoors, in confined spaces, or near sensitive equipment.

• Robust Insulation System:Features Class C or H insulation systems using epoxy resin or VPI treatment, providing excellent resistance to moisture, chemicals, and contaminants, ensuring long-term dielectric strength and operational stability.

• High Efficiency and Low Losses:Designed with high-quality core materials (such as cold-rolled silicon steel) and precision-wound copper or aluminum windings to minimize no-load and load losses, leading to reduced operating costs and improved energy efficiency.

• Excellent Harmonic Handling Capability:Engineered to withstand the thermal and mechanical stresses caused by harmonic currents generated by rectifiers and other non-linear loads, ensuring reliable performance and longevity.

• Low Maintenance and Easy Installation:The self-extinguishing insulation system requires no oil monitoring or filtration, drastically reducing maintenance needs. Its lightweight and compact design compared to oil-immersed equivalents simplifies installation.
