The SBK Three-Phase Dry-Type Transformer offers a reliable, efficient, and advanced power distribution solution tailored for various industrial and commercial uses. With superior craftsmanship, durable construction, and adaptable performance, the SBK series ensures optimal functionality, maintaining stable and secure power distribution across various environments.
Overview of the SBK Three-Phase Dry-Type Transformer
The SBK Three-Phase Dry-Type Transformer comes in two main configurations: open-type and protective-type. These options cater to diverse environmental and operational needs. With low energy losses, minimal noise during operation, outstanding fire resistance, and eco-friendly operation, the SBK series operates without pollution or harmful substances.
Core and Coil Configuration
At its core, the SBK transformer utilizes high-grade iron constructed from cold-rolled silicon steel sheets. This design optimizes energy conservation and heat dissipation, contributing to improved reliability and longer service life. The transformer coils are expertly wound using advanced techniques to significantly minimize electromagnetic interference, ensuring the output waveform remains true to the input waveform.
Protective Enclosure for Enhanced Safety
The protective-type version of the SBK transformer is encased in a robust steel shell that shields the transformer from dust, moisture, and physical impacts. This housing includes built-in cable entry points for easy and secure electrical connections. The transformer can be customized with additional features such as voltmeters, ammeters, temperature controllers, and wheels for increased mobility and real-time operational monitoring.
Wide Range of Applications
The SBK series is highly versatile and is categorized into two types: control transformers and lighting transformers. Control transformers are typically stationary and are ideal for industrial machinery and automation systems, while lighting transformers are portable and widely used on construction sites, in workshops, manufacturing plants, and commercial buildings, excluding machine tools.
Normal Operating Conditions
To maintain the SBK transformer’s performance and reliability, it should be used under standard conditions as outlined below:
- Altitude: Installation should not exceed 2000 meters.
- Temperature: The ambient air temperature should be between -5℃ and +40℃, with a maximum average daily temperature of +35℃.
- Humidity: Relative humidity should remain below 50% at +40℃, although higher humidity (up to 90%) is acceptable at lower temperatures (+20℃).
- Environmental Stability: Sites should be free from intense vibrations, shocks, explosive hazards, corrosive gases, or conductive dust.
Customizable Voltage Configurations
The SBK transformer offers customizable input and output voltage settings to meet specific user requirements. This flexibility allows for seamless integration into various electrical systems, accommodating custom voltage needs without issue.
