Core Selling Points
  • Industrial-Grade Reliability for 24/7 Connectivity: Designed to provide uninterrupted power, preventing network outages and ensuring signal stability for critical communication infrastructure.
  • Superior Electromagnetic Compatibility (EMC): Low-noise and low-vibration design minimize electromagnetic interference, protecting sensitive radio frequency (RF) equipment and high-speed servers.
  • Total Fire Safety for Remote Sites: Self-extinguishing epoxy resin insulation eliminates fire hazards, making it ideal for unattended base stations in residential or forested areas.
  • Optimized Energy Efficiency: Advanced SCB13 core technology reduces no-load losses, significantly lowering operational electricity costs for telecom operators.
Detailed Technical Specifications
  • Capacity Range: 250kVA / 315kVA (Optimized for mid-sized telecom hubs)
  • Voltage Ratio: 11kV Primary / 0.433kV Secondary (Standard 433V for African utility grids)
  • Insulation Class: Class H (180°C) or Class F (155°C) high-temperature endurance
  • Partial Discharge: ≤5pC - 10pC, ensuring a long service life and high insulation reliability
  • Cooling System: Natural Air (AN) with Intelligent Temperature Control; Forced Air (AF) optional for 125% overload handling
  • Core Material: 7-step lap joint CRGO silicon steel to minimize magnetic flux leakage and noise
  • Protection Rating: Standard IP20 for indoor or outdoor cabinets; IP23/IP33 enclosures available for weather protection
Specialized Solutions for African Climate Challenges
Challenge: Excessive Sand & Fine Dust

In arid African regions, dust accumulation often leads to insulation tracking and cooling failure.

Our Solution

Our transformers feature Fully Sealed Vacuum Cast Coils. The smooth, non-porous resin surface prevents fine sand from embedding into the windings. Large, unobstructed cooling channels are designed to be "self-cleaning," allowing wind to blow through particles without buildup.

Challenge: Environmental Hazards & Seepage Risks

Traditional oil transformers suffer from seal degradation in extreme heat, leading to oil leakage and soil contamination.

Our Solution

Our Solid-State Dry Type Design completely removes the liquid medium. By eliminating oil, we offer a zero-leakage guarantee. This removes the need for costly oil containment pits and prevents environmental liability, making it the perfect "Install and Forget" solution for remote telecom sites.

FAQ for Distributors & EPC Contractors
Q: Is this transformer compatible with unstable grid voltages common in Africa?
A: Yes. We include ±2x2.5% tapping ranges on the primary side, allowing easy adjustment to maintain a stable 433V output despite grid fluctuations.
Q: Can you provide the IEC 60076 Test Reports for project tenders?
A: Certainly. Every 250kVA/315kVA unit comes with a full factory test report and IEC compliance certification to support your EPC bidding process.
Q: Does it interfere with high-frequency telecommunication signals?
A: No. Our precision-clamped core design minimizes magnetic flux leakage, ensuring the unit exceeds EMC standards and won't disrupt your radio signals.
Q: What is the maintenance cycle for remote, unattended base stations?
A: Because it is maintenance-free, only a simple visual inspection and light dust cleaning are recommended every 12-24 months.
Q: How do you protect the unit from high ambient temperature (50°C+)?
A: We utilize Class H insulation and a smart thermal controller that triggers auxiliary cooling fans if internal temperatures rise, ensuring safe operation in desert heat.
