Description
Intelligent Distribution Transformer Description
The Intelligent Distribution Transformer is a high-performance Dry Type Distribution Transformer that adopts thin-layer epoxy resin casting to encapsulate high and low-voltage windings. This Dry Type Distribution Transformer boasts core advantages like flame retardancy, self-extinguishing performance, moisture resistance and excellent heat dissipation, eliminating oil leakage and fire hazards inherent in traditional oil-immersed models.
As a cutting-edge Intelligent Distribution Transformer, it integrates advanced smart monitoring functions, fitting seamlessly into key scenarios such as high-rise buildings, airports, docks, power plants, residential communities and complete substations. With voltage compatibility for 6.3kV, 6.6kV and 10.5kV grids, this Dry Type Distribution Transformer delivers low loss, low noise and reliable operation—ideal for both urban infrastructure and industrial distribution systems, fully meeting strict safety and efficiency standards.
Intelligent Distribution Transformer Features
As a next-generation Dry Type Distribution Transformer, this Intelligent Distribution Transformer is specifically engineered to meet the evolving demands of modern power distribution systems—delivering high efficiency, enhanced safety, smart monitoring, and long-term reliability in commercial, industrial, and utility applications.
  • High-Efficiency Core for Distribution Applications:The Intelligent Distribution Transformer utilizes imported high-permeability, cold-rolled grain-oriented silicon steel sheets (thickness ≤ 0.3 mm), precisely stacked in a 45° full oblique step-lap pattern. This design minimizes core losses and acoustic noise—critical for the Dry Type Distribution Transformer installed in urban or indoor environments. A protective resin coating on the core surface ensures robust resistance to moisture and oxidation, extending the service life of the Intelligent Distribution Transformer under tropical or polluted conditions.
  • Intelligent Overload & Thermal Management:Equipped with an integrated smart control system, this Intelligent Distribution Transformer supports dynamic load response. A low-noise forced-air cooling system—automatically activated by embedded temperature sensors—allows the Dry Type Distribution Transformer to operate at up to 140% of rated capacity during peak demand, making it ideal for fluctuating urban or renewable-integrated loads. The smart monitoring module also provides real-time data on temperature, load and operation status, enabling remote management of the Intelligent Distribution Transformer.
