Product Description
Indoor Use 100kVA 11kV to 433V Dry Type Distribution Transformer 3 Phase for Urban Power Grid Project
Product Overview

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.

Key Selling Points
  • 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.
Detailed Technical Specifications
  • 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
Solutions for Challenging Environments

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.

FAQ for Distributors & EPC Companies
Q: Does this transformer comply with local utility standards in Africa?
A: Yes, our design strictly follows IEC 60076 international standards, which are the benchmark for most African national grids (such as Kenya, Nigeria, and Ethiopia).
Q: Can we customize the vector group for specific project requirements?
A: Absolutely. While Dyn11 is standard for urban distribution, we can customize to Yyn0 or other vector groups to match your EPC project specifications.
Q: How do you support EPC contractors during the bidding stage?
A: We provide a full technical documentation package, including type test reports, 3D CAD drawings, and detailed compliance statements to strengthen your tender.
Q: What is the lead time for a bulk order of 10-20 units?
A: Our standard production cycle is 20-25 days. For urgent urban grid projects, we can expedite the schedule through our dedicated export assembly line.
Q: Is the unit compatible with smart grid monitoring?
A: Yes, we can integrate RS485 communication interfaces into the temperature control unit for remote data monitoring and fault alarms.
