Introduction

The SCB Series Three-Phase Cast Resin Dry-Type Transformer is designed for reliable power distribution in applications where electrical safety, energy efficiency, low noise, and long-term operational stability are essential. It features epoxy resin cast windings that provide excellent insulation, mechanical strength, moisture resistance, and resistance to environmental contaminants.

The transformer adopts a three-dimensional toroidal core structure to optimize the three-phase magnetic circuit. The balanced magnetic circuit helps reduce magnetic reluctance, excitation current, and no-load losses, while also contributing to lower operating noise and more uniform temperature distribution across the three-phase windings.

The upper and lower clamping structures securely support the core and windings during manufacturing, transportation, installation, and operation. They also provide effective mechanical support for the coils, improving the transformer's ability to withstand short-circuit forces.

The windings are fully encapsulated in solid epoxy resin, forming an integrated insulation structure with excellent mechanical strength. This construction helps prevent moisture penetration and protects the windings against dust, harmful gases, and chemical contaminants, making the transformer suitable for demanding operating environments.

Typical Applications

The SCB Series Three-Phase Cast Resin Dry-Type Transformer is suitable for power distribution systems that require high safety, energy efficiency, low noise, and reliable operation.

Applications include:

Residential and commercial buildings: Power distribution rooms in residential communities, office buildings, shopping centers, and other commercial facilities.
Hospitals: Power distribution systems near operating rooms, ICUs, and other areas where electrical safety and low noise are important.
Data centers: Power distribution systems serving server rooms and other critical infrastructure.
Transportation infrastructure: Subways, high-speed railway stations, airports, and other transportation facilities.
Space-constrained installations: Basements, floor-level electrical rooms, shopping mall mezzanines, and other locations where compact equipment can help reduce installation space.

Advantages

Adopting a tridimensional toroidal core structure, it offers multiple advantages including energy efficiency, noise reduction, balanced three-phase magnetic circuits, excellent manufacturability, more uniform temperature rise of three-phase coils, and maintenance-free cores that extend service life.

The complete encapsulation of coil conductors in solid epoxy resin insulation not only prevents moisture ingress but also completely blocks corrosion from harmful gases and chemical substances. This delivers outstanding moisture and pollution resistance, ensuring reliable performance in harsh environmental conditions.
