The SBK Three-Phase Dry Type Transformer is an advanced, reliable, and efficient power distribution solution designed to meet diverse industrial and commercial applications. Featuring superior engineering, robust construction, and versatile functionality, the SBK series delivers exceptional performance, ensuring stable and safe power distribution in various environments.
Structural Overview
The SBK Three-Phase Transformador seco is available in two primary structural configurations: open-type and protective-type, catering to different operational and environmental requirements. These transformers offer low loss, minimal operational noise, excellent fire resistance, and environmentally friendly operation, free from pollution and hazardous substances.
Core and Coil Design
At the heart of the SBK transformer is a premium-quality iron core constructed from cold-rolled silicon steel sheets. The design and assembly ensure minimized energy loss and efficient heat dissipation, enhancing operational reliability and longevity. The transformer coils, meticulously wound using advanced winding techniques, significantly reduce electromagnetic interference and distortion, thereby maintaining output waveform integrity identical to the input waveform.
Protective Enclosure
The protective-type SBK transformer is enclosed within a robust steel housing, providing superior protection against dust, moisture, and mechanical impacts. This enclosure is thoughtfully designed with inlet and outlet cable entry points, enabling straightforward and safe electrical connections. Depending on user requirements, additional components like voltmeters, ammeters, temperature controllers, and casters can be incorporated, offering enhanced mobility and real-time operational monitoring.
Versatile Applications
SBK series transformers are versatile and categorized into control transformers and lighting transformers. Control transformers are typically stationary, optimized for industrial machinery and automation systems. Lighting transformers, however, are primarily portable, suitable for a wide range of applications including construction sites, workshops, manufacturing plants, and commercial buildings, except for those specifically used in machine tools.
Normal Usage Conditions
To achieve optimal performance and maintain reliability, SBK transformers should operate under standard conditions:
- Altitude: Installation altitude should not exceed 2000 meters.
- Temperature: Ambient air temperature should remain within -5℃ to +40℃, with a maximum average daily temperature not exceeding +35℃.
- Humidity: Relative humidity should be below 50% at +40℃, though higher humidity levels (up to 90%) are permissible at lower temperatures (+20℃).
- Environmental Stability: Installation sites must be free from severe vibrations, shock, or explosive hazards, and should not contain corrosive gases or conductive dust.
Customized Voltage Configuration
A key benefit of the SBK transformer is its customizable input and output voltage capabilities, tailored to user-specific needs. This flexibility allows integration into diverse electrical systems, accommodating unique voltage requirements seamlessly.
