Durable Construction 2.5MVA 2MVA 1.6MVA Ground Mounted Transformer 11kV to 0.433kV Dedicated to Renewable Energy Plants
Product Overview
The S13 Series High-Performance Ground Mounted Transformer (1.6MVA, 2.0MVA, 2.5MVA) is a specialized power distribution solution engineered for Renewable Energy Plants, including solar farms and wind power stations. Designed for 11kV to 0.433kV step-down applications, this oil-immersed transformer delivers exceptional reliability in harsh outdoor environments. Its robust construction ensures continuous power supply for large-scale industrial factories and utility-scale green energy projects across Africa and the Middle East.
Key Selling Points
Renewable Energy Optimized: Specifically designed to handle the harmonic loads and fluctuating input typical of solar and wind energy conversion.
Superior Thermal Management: Features ultra-wide corrugated cooling fins and high-grade transformer oil for optimal heat dissipation in tropical climates.
Ultra-Low Loss Core: Utilizes premium grain-oriented silicon steel to minimize idle power consumption and maximize project ROI.
Enhanced Weatherproofing: The enclosure is treated with C4/C5 level anti-corrosion coating, providing 20+ years of service life in high-UV and humid conditions.
Detailed Technical Specifications
Advanced Core Technology: The core is constructed with multi-layered, laser-cut silicon steel sheets in a "Step-Lap" stacking method, which significantly reduces noise and magnetic flux leakage.
Precision Winding: 100% Electrolytic Copper windings with high-density pressboard insulation, providing superior mechanical strength to withstand grid short-circuit surges.
Cooling System (ONAN): Natural oil circulation paired with high-surface-area radiators ensures the transformer remains within safe temperature limits even at 100% load in 50°C ambient heat.
Sealing Integrity: Features a fully-welded tank cover and high-performance nitrile or fluoro-rubber gaskets, ensuring a permanent hermetic seal.
Engineering Solutions for Harsh Environments (Dust & Sand Resistance)
In many African regions, fine sand-dust penetration and high thermal stress are the primary challenges that lead to equipment failure.
The Challenge
Fine particulate matter accumulates on traditional seals, causing abrasion and eventual oil leakage, which risks internal contamination and fire hazards.
Our Solution
Triple-Seal Protection: We implement a unique recessed gasket groove design that prevents sand from directly contacting the sealing interface, extending seal life by 300%.
Maintenance-Free Bellows: Instead of traditional air-breathing conservators, we use flexible corrugated fins that expand and contract. This eliminates the intake of dust-laden air entirely.
Reinforced Leak-Proof Valves: All drainage and sampling valves are fitted with protective dust caps and double-layered O-rings to ensure zero seepage in desert conditions.
FAQ (For EPC Companies & Distributors)
Q: Can this transformer be integrated into a prefabricated substation (Kiosk)?
A: Yes, our 1.6MVA to 2.5MVA units are compact-designed to fit perfectly into containerized substations or outdoor enclosures.
Q: Does it meet the specific requirements for Solar PV inverter connection?
A: Absolutely. We provide specialized dual-winding or multi-winding configurations compatible with various central inverter outputs.
Q: What certifications do you provide for government tenders?
A: We provide complete IEC 60076 Test Reports, ISO 9001/14001 certificates, and can facilitate SGS or Intertek pre-shipment inspections.
Q: How do you protect the equipment against the intense African sun?
A: We apply specialized UV-resistant polyurethane paint that reflects heat and prevents the outer coating from cracking or chalking.
Q: Are spare parts included for remote project sites?
A: We offer customized "Commissioning Kits" which include extra gaskets, bushings, and oil level gauges for immediate on-site support.
Q: What is the standard warranty period for renewable energy projects?
A: We offer a standard 12-month warranty, with options to extend based on project specificities.
