ABB dry type transformer

ABB dry type transformers are essential components designed for various electrical applications, providing reliable and efficient power distribution in both industrial and commercial environments. Unlike oil-filled transformers, dry type transformers use air or resin for insulation and cooling, which makes them safer and more environmentally friendly.

Key Specifications and Features:

Simplified inspection and maintenance routines can be performed without specialized equipment.

Model Types:

Available in various models such as SCB10, SCM10, and others, catering to different capacities and voltage levels.

Rated Capacity:

Capacities can range widely, with options commonly up to several MVA (Mega Volt-Amperes), such as the SCB10-3150/20(10) model with a capacity of 3150 kVA.

Design and Construct:

Dry Type Construction: Utilizes ambient air for cooling, eliminating the risk of oil leakage or fire hazards.

Compact Design: Saves space and minimizes installation footprint while maintaining high performance.

Voltage Ratings:

High voltage ratings such as 10 kV and 20 kV are common, with low voltage typically at 400 V.

Cooling Method:

Air Natural (AN) or forced air cooling options are available to meet specific operational needs.

Insulation Level:

High voltage insulation levels capable of withstanding high environmental stress, typically rated around 12/≤1.1 kV.

Environmental Resilience:

Designed to operate efficiently in harsh environments, with protection against dust and moisture.

Environmental ratings (like E2 for pollution degree and C2 for climate) indicate suitability for outdoor use in various climatic conditions.

Safety Features:

Equipped with over-temperature protection and fault detection capabilities to ensure safe and reliable operation.

Meets rigorous international standards for safety and emissions.

Applications:

Ideal for use in commercial buildings, industrial facilities, data centers, and renewable energy applications such as wind and solar farms.

Often deployed in places where space is limited, and environmental safety is a priority.

Service and Maintenance:

Requires less maintenance compared to oil-filled transformers due to the absence of insulating oil.
