Description

30KVA Oil Immersed Transformer

Behold our flagship S11-M-30 Three Phase Transformer, a paradigm of robust engineering in power distribution. Unlike generic models, this 30KVA oil immersed transformer features a meticulously crafted corrugated tank wall, which not only provides a larger heat dissipation surface but also enhances mechanical strength without the need for external welding ribs.

The compact, streamlined design is finished with a high-durability, corrosion-resistant coating, specifically formulated to withstand harsh industrial environments. Every component is designed for longevity and minimal maintenance, ensuring this unit isn’t just another 30 kva transformer, but a long-term, reliable asset for your operational infrastructure, offering superior value beyond the initial transformer oil price.

Service Conditions

• Ambient Temperature: The equipment is designed to operate within an ambient temperature range of -25℃ to +40℃.

• Altitude: The installation site altitude should be less than 1000 meters above sea level.

• Humidity: The maximum monthly average relative humidity is 90% at 20℃.

• Installation Location: The equipment must be installed in a location free from fire, explosion hazards, severe pollution, chemical corrosion, and excessive vibration. It is suitable for both indoor and outdoor installation, provided the specified environmental conditions are met.

Product Features

• High-Efficiency Core
  The transformer core is constructed from imported, high-grade cold-rolled silicon steel laminations. This material, combined with an advanced core-binding process, ensures exceptional magnetic permeability and compactness. The result is a significant reduction in both no-load loss and no-load current, enhancing overall energy efficiency. Furthermore, this robust construction effectively minimizes core vibration and audible noise during operation.

• Premium Windings
  Both the high and low voltage windings are meticulously wound using high-purity oxygen-free copper conductors to ensure low resistance and high conductivity. For optimal performance, the low-voltage windings employ a double-layer cylindrical structure for capacities of 500kVA and below. For higher capacities (630kVA and above), a double or even quadruple spiral structure is adopted to effectively handle larger currents. The high-voltage winding utilizes a multi-layer cylindrical structure, providing excellent voltage endurance and impulse strength.

• Advanced Connection
  The standard Dyn11 connection group is employed. This configuration is highly effective in suppressing third-harmonic currents and provides a neutral point for load earthing. This significantly reuces the impact of harmonics on the power grid, leading to a cleaner and more stable power supply with improved quality.

• Robust & Maintenance-Free Design
  The transformer features a fully sealed, maintenance-free construction. By eliminating the need for a conservator (oil tank) and isolating the internal insulating oil from atmospheric moisture and oxygen, this design effectively prevents oil degradation. This robust sealing technology considerably prolongs the service life of the insulation and the transformer itself, requiring minimal operational intervention.

• Low Noise Operation
  Through optimized core design, secure clamping, and thoughtful manufacturing, the transformer operates exceptionally quietly. Measured noise levels are consistently lower than the limits stipulated by relevant standards, making it an ideal choice for noise-sensitive environments such as residential areas and urban installations.

Technical Drawing

Precision engineering demands precise planning. This detailed dimensional schematic provides the exact footprint and critical clearances required for the seamless integration of our transformer 30kva into your facility layout. The drawings highlight key installation points, including the positioning of lifting lugs (hanging plates) and cable entry locations.

By providing these accurate blueprints, we empower your engineering team to pre-plan cable routing and foundation work, significantly reducing on-site installation time and costs. This commitment to detailed pre-delivery support is a core part of our service, distinguishing us from suppliers who offer only basic specifications.

Product Model Meaning

Decoding our model name reveals a commitment to transparency and advanced engineering. The ‘S’ stands for our Three Phase Transformer design, optimized for balanced load distribution. The ’11’ is not just a code; it signifies our adoption of the advanced, low-loss S11 performance standard, which drastically reduces no-load currents compared to older S9 models.

The ‘M’ represents our Fully Sealed, Maintenance-Free philosophy. Once filled with high-performance transformer insulating oil, the unit is permanently sealed under a vacuum, eliminating moisture ingress and the need for frequent oil sampling or replenishment, a common hassle with conventional oil type transformers. Finally, the ’30’ confirms its precise 30KVA rating, ensuring you get the exact capacity you pay for.

Transparency in performance is non-negotiable. This comprehensive data sheet validates the exceptional efficiency of our S11-M-30 Three Phase Transformer. Pay close attention to the critically low no-load and load loss (W) figures, which translate directly into significant energy savings over the transformer’s lifetime, far outweighing the initial transformer oil price.

The detailed voltage combination and tapping range (%) provide the flexibility needed for various grid applications. Furthermore, the optimized short-circuit impedance (%) ensures stable performance under fault conditions. This table is not just a list; it’s a testament to an engineering philosophy focused on total cost of ownership, not just the initial purchase price.

Product Workshop

Superiority lies in the details. This close-up reveals the uncompromising quality embedded in our 30KVA oil immersed transformer:

1. Transformer Body: We construct the tank from cold-rolled steel, forming it into corrugated panels to achieve superior strength and a 20% larger radiation surface than flat tanks, which ensures exceptional overload capacity and impact resistance.

2. Terminal: We use high-conductivity, pure copper terminals with laser-etched wiring instructions. We design them with anti-loosening features and superior plating. These prevent corrosion and ensure long-term reliability. Each connection stays secure and easy to install.

3. Pure Copper Windings: At the heart of this oil transformer are 100% electrolytic grade copper windings. Copper offers higher conductivity and superior mechanical strength compared to aluminum, providing enhanced short-circuit withstand capability (dynamic stability) and better thermal performance (thermal stability).

4. Heat Sink: We computationally arrange the corrugated radiator fins based on thermal dynamics to create optimal airflow. This design dissipates heat from core losses faster and maintains a stable temperature for the transformer oil.

5. Oil Level Gauge: Our magnetically driven oil level gauge with a tri-color indicator (Red-Low, Blue-Normal) provides a clear, reliable visual check from any angle, ensuring the integrity of the sealed system and the correct level of transformer insulating oil at all times.
