Product Description
Low Loss 20kV 0.4kV Three Phase Power Distribution Transformer 1250/1000 kVA Stable Voltage Supply for Infrastructure Development
The Low Loss 20kV to 0.4kV Three Phase Power Distribution Transformer (1000kVA / 1250kVA) is a high-capacity power solution precision-engineered for Infrastructure Development, industrial parks, and grid substations. Optimized for superior voltage stability, this oil-immersed unit utilizes advanced core technology to minimize energy dissipation. Designed specifically to meet the rigorous demands of the African power market, it ensures a consistent and stable electrical supply for large-scale engineering projects and heavy industrial loads.
Key Selling Points
- Maximum Energy Efficiency: Utilizing high-permeability silicon steel, the S11 design drastically cuts no-load losses, translating into significant long-term operational savings for grid operators.
- Superior Load Stability: Specifically tuned for 1000kVA and 1250kVA capacities, it provides consistent output voltage even during sudden demand spikes in infrastructure operations.
- Hermetically Sealed Maintenance-Free Design: The vacuum-sealed corrugated tank prevents oil oxidation, extending the insulation life to over 30 years without the need for periodic oil filtration.
- High-Grade Copper Windings: Built with 99.9% oxygen-free copper, ensuring high thermal conductivity and the mechanical strength required to resist short-circuit stresses.
Detailed Technical Specifications
- Rated Capacities: 1000 kVA / 1250 kVA (Dual capacity options available)
- Voltage Ratio: High Voltage (HV) 20kV / Low Voltage (LV) 0.4kV (400V)
- Core Engineering: Multi-step lap joints reduce noise levels and magnetic flux leakage, surpassing international IEC standards
- Vector Group: Dyn11 or Yyn0, providing flexible grounding and harmonic suppression options for various grid types
- Corrugated Tank Technology: Elastic radiator fins automatically adjust to oil thermal expansion, maintaining constant internal pressure
- Surface Protection: C4-grade industrial anti-corrosion coating prevents rust in high-humidity or coastal substation environments
Specialized Solutions for Sandy & Dusty Environments
Operational Challenge: In regions with heavy sandstorms and high dust concentration, particles often accumulate in traditional oil conservators, causing seal degradation and hazardous oil leakage.
Our Engineering Solution:
- Elimination of External Breathers: Our fully sealed corrugated tank eliminates the traditional conservator. By removing the air-breathing path, we completely block fine sand and dust from contaminating the internal mineral oil.
- Reinforced Double-Weld Seams: To prevent leakage under extreme temperature fluctuations, all tank joints are reinforced with double-pass robotic welding and subjected to 0.05MPa pressure testing.
- Anti-Dust Bushing Shields: High-voltage bushings are equipped with protective skirts to prevent dust accumulation, reducing the risk of flashovers and electrical tracking in arid climates.
FAQ for Distributors & EPC Companies
Q1: How does this transformer handle the high-load demands of infrastructure projects?
A1: Our 1250kVA units are designed with optimized oil channels to ensure rapid heat dissipation, allowing for reliable operation during the continuous heavy loads typical of construction and manufacturing.
Q2: Are these units compatible with the local 20kV grids found in various African countries?
A2: Yes, we provide off-circuit tap changers (±5% or ±2*2.5%) that allow for precise voltage adjustment to match specific local grid conditions.
Q3: What is the typical service life in a high-dust desert environment?
A3: With our hermetically sealed design and dust-proof coatings, the expected service life exceeds 30 years with minimal on-site intervention.
Q4: Do you provide technical documentation for EPC tender submissions?
A4: Absolutely. We provide comprehensive CAD drawings, technical data sheets, and compliance certificates to assist our partners in winning tenders.
Q5: Can you manage the logistics for heavy 1250kVA units to inland project sites?
A5: Yes, we offer door-to-port or door-to-site shipping solutions with reinforced packaging designed to withstand rough terrain transportation.
