Description
Description
Built for AC 50Hz power systems , these 6.3kV/24kV/33kV S11-M units are ideal distribution transformers for petroleum, metallurgy, chemical, textile, and light industrial facilities—including dust-heavy environments.
Their fully sealed design prevents oil leaks, blocks dust/moisture, and enables maintenance-free long-term operation. With low loss, low noise, and strong overload capability, they deliver stable power even in harsh conditions, meeting industrial-grade reliability demands.
Feature
  • Full Hermetic Sealing Design：Eliminates oil leakage risks and effectively isolates dust, moisture and corrosive gases from the external environment, ensuring stable operation in harsh conditions like dusty industrial workshops.
  • Low Loss & High Energy Efficiency：Adopts advanced core and coil structure, significantly reducing no-load and load losses, cutting down long-term energy consumption, and complying with global high-efficiency power equipment standards.
  • Wide Application Compatibility：Optimized for AC 50Hz power systems, ideal for petroleum, metallurgy, chemical, textile and light industry sectors, perfectly matching the power distribution needs of special industrial scenarios.
  • Low Noise & Maintenance-free Operation：Integrates noise reduction structural design for quiet running; the sealed structure avoids regular oil replacement and maintenance work, lowering the overall operation and maintenance costs.
  • Strong Overload & Short-circuit Resistance：Reinforced clamp and frame structure enhances mechanical strength, with excellent overload capacity and short-circuit withstand performance to cope with sudden load fluctuations in industrial grids.

FAQ
Q: What core advantages does the Fully Sealed Oil-Immersed Power Distribution Transformer have over ordinary power distribution transformer, and how does its sealed design boost performance?
A:
The Fully Sealed Oil-Immersed Power Distribution Transformer is a high-reliability power distribution transformer variant, with its key edge being the fully sealed structure. Unlike conventional power distribution transformer with open or semi-sealed tanks, it isolates transformer oil from air, moisture, and dust, preserving oil insulation performance, avoiding oxidation, and extending the power distribution transformer’s service life.
It eliminates regular oil replacement and breather maintenance, cutting long-term costs. The oil-immersed design ensures efficient heat dissipation for full-load stable operation, and the sealed structure enhances resistance to harsh environments—making this power distribution transformer ideal for outdoor, industrial, and high-humidity scenarios where ordinary models may fail.
