SCB Series Resin Insulated Dry-type Transformer

Product Introduction

The SCB Series Resin Insulated Dry-type Transformer is designed for reliable power distribution in commercial, industrial, and infrastructure applications where electrical safety, operational stability, and reduced maintenance are important. It uses epoxy resin vacuum casting technology to provide strong mechanical and electrical insulation performance.

The resin-insulated construction offers good moisture resistance and helps the transformer maintain stable operation in demanding environments. With a capacity range from 30kVA to 2500kVA and voltage specifications of 10kV/0.4kV, the SCB series can be configured for a wide range of medium-voltage to low-voltage distribution requirements.

Key Product Features

Low Loss and Low Noise Operation

The optimized magnetic core structure helps reduce no-load loss and operational noise. This makes the transformer suitable for buildings and facilities where energy efficiency and acoustic performance are important.

Epoxy Resin Vacuum Casting

The winding insulation is formed through epoxy resin vacuum casting technology. This construction provides strong electrical insulation and mechanical strength while helping protect internal components against moisture and environmental influences.

Fireproof and Flame-Retardant Construction

The epoxy resin insulation is non-flammable and self-extinguishing. The dry-type design eliminates the need for transformer oil, making it suitable for locations where fire safety is a key consideration.

Strong Short-Circuit Resistance

The high mechanical strength of the resin-insulated winding structure allows the transformer to withstand significant electromagnetic forces generated during short-circuit conditions, supporting reliable operation in demanding power distribution systems.

Moisture-Resistant and Maintenance-Friendly

The solid insulation structure provides good resistance to moisture and environmental conditions. Compared with oil-filled transformer systems, the dry-type configuration can reduce routine maintenance requirements and simplify installation in many indoor applications.

Long Service Life

The SCB series is designed for long-term operation with stable insulation performance and reliable thermal characteristics. Depending on operating conditions and maintenance practices, it can support long-term power distribution requirements.

Flexible Capacity Range

Available rated capacities range from 30kVA to 2500kVA, allowing the series to cover different load requirements from smaller commercial installations to larger industrial and infrastructure power systems.

Technical Specifications

Insulation and Safety Design

The SCB series uses a resin-insulated dry-type structure instead of liquid insulation. Epoxy resin vacuum casting helps form a compact and mechanically stable insulation system around the windings.

This design is particularly suitable for facilities where fire protection, electrical safety, and environmental reliability need to be considered together. The absence of transformer oil also removes the need for oil containment and oil-related maintenance.

The resin insulation system provides electrical insulation while contributing to mechanical strength. This helps the transformer withstand electrical and mechanical stresses during normal operation and short-circuit events.

Thermal Performance

Temperature management is an important factor in dry-type transformer operation. The SCB series uses a natural cooling configuration and is available with temperature-rise limits of 100K or 125K according to the specified configuration.

The thermal design supports stable operation under appropriate rated loads while helping maintain the service life of the insulation system. Proper ventilation and installation clearance should be considered during system design to ensure effective heat dissipation.

Connection and Voltage Configuration

The standard voltage specification is 10kV / 0.4kV, making the series suitable for medium-voltage distribution systems supplying conventional low-voltage electrical loads.

The available connection symbols include Dyn11 and Yyn0. The appropriate connection configuration can be selected according to the requirements of the power distribution system, load characteristics, and electrical design.

Application Areas

The SCB series resin insulated dry-type transformer can be used in a wide range of power distribution environments, including:

High-Rise Buildings

Suitable for electrical distribution systems in high-rise commercial and residential buildings where fire safety, space utilization, and reliable power supply are important.

Commercial Centers

The low-noise and dry-type design makes the transformer suitable for shopping centers, commercial complexes, and other facilities with continuous electrical loads.

Airports and Railway Stations

The equipment can be integrated into infrastructure power distribution systems requiring reliable medium-voltage to low-voltage transformation and stable operation.

Subways and Tunnels

The dry-type structure is suitable for underground transportation infrastructure where fire safety and dependable electrical equipment are essential.

Chemical Plants

The resin-insulated construction can be applied to industrial power distribution systems where equipment reliability and environmental resistance are important design considerations.

Underground Power Stations

The compact dry-type configuration can be used in underground electrical facilities where liquid-filled transformer equipment may not be preferred.
