Product Description
High Voltage Distribution Transformer 125kva 100kva 20kv 0.4kv Low Loss Three Phase Power Supply for Construction Sites
Product Overview

The S11 series high-voltage distribution transformer is a high-performance, energy-efficient solution specifically engineered for demanding construction sites and industrial power distribution. With a rated voltage of 20kV to 0.4kV and capacities of 100kVA and 125kVA, this three-phase oil-immersed unit complies with IEC 60076 standards. It provides a stable and continuous power supply for heavy machinery, temporary site housing, and engineering grids, ensuring your project remains powered under the most rigorous conditions.

S11 series high-voltage distribution transformer for construction sites
Key Features
Maximum Energy Efficiency
Optimized S11 design reduces no-load losses by 30%, significantly lowering operational costs for long-term construction projects.
Unrivaled Site Adaptability
Features a robust, weather-resistant exterior and heavy-duty lifting lugs, making it easy to relocate and install on uneven construction terrain.
Maintenance-Free Operation
The hermetically sealed tank prevents oil aging and oxidation, drastically reducing the frequency of onsite technical interventions.
High Short-Circuit Resistance
Precision-wound copper coils offer superior mechanical strength, protecting the unit from the power surges common in heavy industrial start-ups.
Technical Specifications
  • Core Material: High-permeability, cold-rolled grain-oriented silicon steel (CRGO) for minimal magnetic hysteresis and low heat generation
  • Winding Technology: High-purity oxygen-free copper windings provide excellent conductivity and thermal stability under 100% load
  • Cooling System: Natural Oil Air (ONAN) cooling with high-efficiency corrugated radiators for rapid heat dissipation
  • Insulation Class: Class A insulation with high-flash-point mineral oil for safety in high-ambient-temperature environments
  • Tapping Range: Off-circuit tap changer (±5% or ±2x2.5%) for precise output voltage adjustment
Specialized Solutions for Arid & Dusty Environments

In many African regions, excessive dust and sandstorms pose a major challenge to electrical equipment, often leading to seal degradation and oil leakage. We have implemented specific engineering upgrades to address these challenges:

Challenge: Airborne sand particles act as abrasives
Solution: Double-Sealed Fluororubber Gaskets offer superior resistance to abrasion and UV radiation compared to standard nitrile rubber.
Challenge: Dust accumulation on cooling fins causing overheating
Solution: Streamlined Corrugated Tank Design prevents dust trapping and features Anti-Static Polyester Powder Coating to minimize dust adhesion.
Challenge: Oil contamination
Solution: Fully Hermetical Vacuum Filling Technology ensures zero air pockets and zero contact with outside atmosphere, keeping oil pure despite heavy exterior sand.

Frequently Asked Questions
Does this transformer comply with local utility grid requirements in Africa?
Yes, our units are built to IEC 60076 standards and are widely accepted by utility boards across Africa (e.g., Kenya, Nigeria, South Africa) for both private and public grids.
How do you ensure the transformer survives long-distance shipping to inland projects?
We use reinforced steel-framed packaging and anti-vibration padding, ensuring the internal core and coils remain stabilized during sea and rugged land transport.
Can we customize the primary voltage if our site uses a non-standard 20kV grid?
Absolutely. As a manufacturer, we can customize primary voltages (e.g., 11kV, 15kV, 22kV, 33kV) to match your specific EPC project requirements.
What is the typical lead time for an urgent construction project?
For standard 100kVA/125kVA units, we maintain a rolling stock or can prioritize production to ship within 15-20 days.
What technical support do you offer for onsite installation?
We provide comprehensive installation manuals, 24/7 remote video technical guidance, and detailed test reports for all electrical commissioning.
