Premium Efficiency 11kV to 0.433kV Power Transformer S13 2500kVA/2000kVA for Industrial Factory Electricity Supply
Product Overview

The S13 Series Oil-Immersed Distribution Transformer (2000kVA/2500kVA) is a high-performance, low-loss power solution engineered for demanding industrial environments. Specifically designed for 11kV to 0.433kV step-down applications, this transformer complies with IEC60076 standards. It offers a robust energy-saving design that significantly reduces operational costs for industrial factories, mining sites, and urban infrastructure across the African continent.

S13 Series Oil-Immersed Distribution Transformer industrial installation
Key Features & Benefits
  • Superior Energy Efficiency: 30% reduction in no-load loss compared to S11 models, ensuring long-term electricity savings
  • 100% Pure Copper Windings: High-conductivity copper ensures excellent thermal stability and strong short-circuit resistance
  • Hermetically Sealed Design: Vacuum oil-filling process and corrugated tank structure eliminate the need for an oil conservator, reducing maintenance requirements
  • High-Temperature Resilience: Specifically optimized cooling radiators designed to maintain peak performance in tropical and arid climates
  • Enhanced Insulation: Utilizes premium-grade insulation materials to prevent electrical failure under fluctuating grid conditions
Technical Specifications
Core Material High-permeability, grain-oriented cold-rolled silicon steel sheets with 45-degree fully oblique joint structure to minimize magnetic loss
Winding Technology Spiral or continuous winding structure with specialized bracing to ensure mechanical strength during heavy-duty industrial starts
Cooling System ONAN (Oil Natural Air Natural) cooling with high-surface-area corrugated fins for rapid heat dissipation
Voltage Regulation Equipped with Off-Circuit Tap Changer (OCTC) with ±2×2.5% or ±5% range to adapt to unstable input voltages
Protection Accessories Includes high-reliability pressure relief valves, oil level indicators, and signal thermometers for real-time monitoring
Specialized Solutions for Challenging Environments
The Challenge:

In many African regions, high sand-dust density and extreme heat often lead to seal degradation and oil leakage, compromising transformer lifespan due to dust accumulation on seals and traditional conservators.

Our Engineering Solutions:
  • Integrated Corrugated Tank: Fully sealed, bolt-free welding process for the tank cover to minimize leakage points
  • Premium Fluoro-rubber Gaskets: All interfaces equipped with high-grade fluoro-rubber seals that resist UV radiation and sand abrasion, maintaining elasticity in 50°C+ environments
  • Automated Leak Testing: Every unit undergoes 24-hour positive pressure test and ultrasonic flaw detection to ensure zero-leakage before shipment
Frequently Asked Questions
Does the transformer comply with local African grid standards?
Yes, our S13 series is manufactured strictly according to IEC 60076 standards and can be customized to meet specific national grid requirements in Nigeria, Kenya, Ethiopia, etc.
How do you ensure the safety of long-distance sea freight?
We use reinforced steel-base pallets and moisture-proof vacuum packaging, secured within the container to prevent any movement during transit.
Can you provide Type Test Reports for EPC project bidding?
Absolutely. We provide full sets of Routine Test Reports and can facilitate Third-Party Type Tests (KEMA/SGS) upon request.
What is the lead time for a 2500kVA unit?
Standard production takes 20-30 days. For urgent EPC projects, we can fast-track the assembly to meet your project timeline.
How do you handle after-sales support in remote areas?
We provide 24/7 remote technical guidance and ship essential spare parts kits with every order. Local service partners are available in key regions.
