Products Description of Oil Immersed Electrical Distribution Transformer
Manufacturing Technology
Oil-Filled Process (oil filled): High-purity transformer oil is used to enhance insulation and heat dissipation, minimizing partial discharge risks.
Oil-Cooled System Innovation (oil cooled distribution transformer): Optimized oil circulation design improves cooling efficiency by 20%, enabling continuous heavy-load operation.
Fully Sealed Structure: Vacuum oil filling and pressure testing prevent leaks, meeting IP23 protection standards.
Material &Craftsmanship:
High-Permeability Silicon Steel Sheets: Reduces iron losses, achieving energy efficiency above 98%.
Corrosion-Resistant Coating: Epoxy resin coating withstands coastal or industrial pollution.
Certifications: Complies with ISO 9001 and IEC 60076 standards, ensuring reliability and safety of oil-immersed transformers.
Application Environment of oil cooled distribution transformer
Climate Resilience:
The oil cooled distribution transformer operates stably between -30°C and +50°C, ideal for regions like Georgia with extreme temperature fluctuations.
Resists humidity, salt fog corrosion, and suits coastal or high-humidity areas.
Industrial Suitability:
Oil filled distribution transformers handle voltage fluctuations, meeting heavy industrial demands (e.g., metallurgy and chemical industries).
Supports parallel operation to expand power distribution capacity (oil distribution transformer).
Specialized Scenarios:
Ideal for mountainous or remote areas, reducing maintenance needs and lowering operational costs.
