In-Stock ABB Transformers: Optimal Solutions for Diverse Power Needs
Versatile Applications: Our range of ABB transformers is ideal for a variety of applications—from residential overhead distribution to light commercial and industrial uses. Whether you require a single phase load supply or a robust three-phase system, our transformers can be easily mounted on wooden, concrete, or clustered poles, ensuring flexibility and efficiency for all power distribution needs.
Compliance and Standards: Built to meet stringent industry standards, our in-stock transformers comply with CAN CSA C2.1-06 and CAN CSA C2.2-06, with adaptations available to meet specific customer specifications. Additionally, they conform to international standards such as IEEE C57.12.20 and IEC, depending on your requirements.
Features for Performance:
- Core and Coil: Designed to minimize Total Ownership Costs through increased efficiency and reduced noise levels.
- Innovative Winding Configurations: Low-high-low windings that enhance short circuit strength, operational efficiency, and thermal resilience.
- Dual Voltage: Engineered to handle multiple voltage requirements, ensuring versatility and reducing inventory needs for utilities.
- Safety and Durability: Includes an automatic self-resealing pressure relief valve and a durable paint system that surpasses IEEE C57.12.28 standards for salt spray.
Dual Voltage Transformers and Taps: Our dual voltage transformers offer the flexibility needed to adapt to changing voltage requirements without the need for frequent replacements, making them a cost-effective choice. Recommended configurations limit the high voltage (HV) spread to ensure reliability and performance longevity.
General Specifications:
- Temperature Rise: Standard 65°C
- Cooling Type: ONAN for optimal heat dissipation
- Frequencies Supported: 60 Hz
- Insulation Class: Up to 25kV (150kV BIL)
- Taps: 4 x 2.5% HV
