Indoor Use 100kVA 11kV to 433V Dry Type Distribution Transformer 3 Phase for Urban Power Grid Project
The 100kVA 11kV to 433V Dry Type Distribution Transformer is a high-performance, three-phase power solution specifically engineered for urban power grid modernization and industrial infrastructure. Leveraging advanced vacuum cast coil technology, this unit provides a safe, fire-resistant, and highly reliable alternative to traditional oil-filled transformers. Designed to meet IEC 60076 standards, it is the preferred choice for commercial complexes, residential zones, and mission-critical public utilities.
- Maximum Safety & Fire Retardancy: Self-extinguishing epoxy resin insulation eliminates fire hazards and toxic gas emissions, ensuring safety in high-density urban areas.
- Exceptional Energy Efficiency: Built with high-permeability silicon steel cores to minimize no-load losses, significantly reducing long-term operational costs for grid operators.
- Maintenance-Free Reliability: The solid insulation design eliminates the need for oil level checks, gas testing, or gasket replacements, saving labor and material expenses.
- Extreme Thermal Management: Equipped with high-precision temperature sensors and a forced-air cooling system to maintain peak performance even under heavy loads or high ambient temperatures.
- Insulation Class: Class F or Class H (capable of withstanding internal temperatures up to 155°C/180°C)
- Cooling Method: Natural Air (AN) or Forced Air (AF) for 125% overload capacity
- Partial Discharge: Controlled under ≤10pC, ensuring an ultra-long service life of over 20 years
- Enclosure Rating: Standard IP20 for indoor use, customizable up to IP23 or IP31 for enhanced protection
- Tapping Range: Primary side ±2x2.5% off-circuit tap changer for flexible voltage regulation
- Core Structure: Three-limb core made of cold-rolled grain-oriented (CRGO) silicon steel with step-lap joints to reduce noise levels
The Issue: Sand & Fine Dust Accumulation - In many African regions, airborne sand can infiltrate traditional units, causing mechanical wear or cooling blockages.
Our Solution: We utilize a Fully Encapsulated Vacuum Casting process. The smooth, hard surface of the resin prevents dust from adhering to the windings, and the enlarged cooling ducts are designed to be "self-cleaning" via natural airflow.
The Issue: Environmental Contamination & Oil Leakage - Oil-immersed transformers pose a risk of soil contamination and require complex oil pits.
Our Solution: Our Solid-Cast Dry-Type Design completely removes the liquid medium. There is zero risk of oil leakage or spill-related environmental hazards, making it ideal for fragile urban ecosystems and reducing civil engineering costs for oil containment.
