The Energy Saving 20kV to 0.4kV Three Phase Oil Immersed Transformer is specifically engineered for high-demand environments such as construction sites and infrastructure projects. Available in 630kVA and 800kVA capacities, this hermetically sealed unit ensures high-efficiency power distribution with minimized energy loss. It is the ideal power solution for rugged terrains and temporary power grids, providing stable voltage for heavy machinery and site facilities.
- Eco-Friendly Energy Efficiency: Optimized S11 core design reduces no-load losses, significantly lowering electricity costs for long-term projects.
- Fully Hermetically Sealed Structure: The vacuum-filled mineral oil is isolated from air, preventing oxidation and moisture, making it virtually maintenance-free.
- Robust Weatherproof Housing: Treated with anti-corrosive industrial coatings, the tank withstands extreme UV exposure and harsh outdoor conditions.
- High Overload Capacity: Built with premium copper windings to handle the sudden current surges common in construction machinery.
- Standard Compliance: Fully compliant with IEC60076 and international distribution standards.
- Core Material: High-permeability, grain-oriented cold-rolled silicon steel for superior magnetic flux.
- Cooling Method: ONAN (Oil Natural Air Natural) with enhanced corrugated radiator fins for maximum heat dissipation surface.
- Insulation Class: Class A insulation with high-grade transformer oil (PCB-free) for safe operational thermal limits.
- Tapping Range: ±5% or ±2x2.5% off-circuit tap changer to adjust to local grid fluctuations.
The Challenge: In dusty African regions, fine sand can clog traditional breathers and degrade seals, leading to hazardous oil leakage and internal contamination.
- Breather-Free Design: Our hermetically sealed corrugated tank absorbs oil volume changes through the elasticity of the fins, eliminating the need for a traditional conservator and breather, thus blocking all dust entry.
- Precision Multi-Point Welding: We utilize automatic robot welding for the corrugated tank and base, followed by a 24-hour high-pressure leak test to ensure zero seepage.
- Advanced Sealing Gaskets: We use high-performance acrylate rubber gaskets that remain flexible and crack-resistant under the scorching African sun, ensuring a permanent seal.
