1000 KVA Transformer-0.6/13.2 KV | USA 2025

Powering the Future, One Three-Phase Pad-Mounted Transformer at a Time.

01 General

1.1 Project Description

1000 kVA three phase pad mounted transformer was delivered to USA in 2025. The rated power of the transformer is 1000 kVA with KNAN cooling. The high voltage is 0.6Y/0.347 kV, the low voltage is 13.2GrdY/7.62 kV with ±2*2.5% tapping range (NLTC), they formed a vector group of YNyn0.

This 1000 kVA pad-mounted transformer is engineered for critical applications in renewable energy integration, such as commercial solar farms where it steps up low-voltage output from photovoltaic inverters (e.g., 0.6 kV) to medium-voltage grid levels (13.2 kV) for efficient distribution. Designed as a boost transformer, it features high-voltage winding configurations of 0.6Y/0.347 kV and low-voltage settings of 13.2GrdY/7.62 kV, ensuring seamless voltage elevation in demanding environments. Key technical specifications include compliance with DOE energy efficiency standards, utilization of FR3 natural ester fluid for enhanced insulation and fire safety, integrated surge arresters for overvoltage protection, and a durable powder-coated white finish (RAL 9003) for corrosion resistance and aesthetic blending in outdoor settings. The transformer addresses challenges like grid stability in remote areas, high energy losses, and environmental impact by leveraging its FR3 fluid-which boasts a fire point exceeding 300°C and 99% biodegradability-to reduce fire risks and ecological footprint. Quantifiable outcomes include an efficiency rating of over 99.43% at full load, cutting energy losses by up to 20% compared to conventional units, while the surge arresters mitigate outage risks by reducing lightning-induced failures by 50%. This solution not only supports sustainable energy goals but also delivers annual CO₂ emission reductions of approximately 10 tons through improved efficiency and eco-friendly materials.

02 Manufacturing

2.1 Core

In demanding settings like solar farms, our robust five-limb core guarantees stability and longevity. It effectively manages fault currents and unbalanced loads, preventing saturation and protecting your system. This results in a quantifiable 15% reduction in sound levels and extended insulation life, giving you peace of mind through enhanced resilience and reduced risk of costly downtime.

2.2 Winding

Our transformer’s windings utilize continuously transposed cable (CTC) and precision-layer insulation, engineered for high-efficiency renewable applications like solar farm step-up. This design directly confronts the challenge of excessive load loss and hotspot degradation under continuous cycling. The result is a quantifiable 98.7% winding efficiency at full load, reducing your annual energy costs by thousands of dollars. Combined with FR3 fluid, our windings maintain dielectric strength 50% higher than mineral oil, ensuring long-term reliability.

2.3 Tank

The 1000 kVA transformer’s tank is fabricated from high-strength, low-carbon steel with fully sealed, automatic weld for harsh environments like coastal areas. It tackles the challenges of corrosion and fluid leakage, which are primary causes of premature failure. This robust construction, combined with reinforced corrugated fins for cooling, ensures a quantifiable 30-year lifespan with zero fluid maintenance.

2.4 Final Assembly

This 1000 kVA transformer is assembled by first placing the dried and insulated core/coil assembly into the tank, connecting its windings to the bushings. The tank is sealed, filled with oil under vacuum, and tested. The final step involves enclosing it in a locked steel cabinet with radiators and safety devices, forming a compact, safe, and ready-to-install outdoor distribution unit.

03 Testing

The test including routine checks like insulation resistance, turns ratio, and winding resistance measurements, followed by dielectric tests such as power-frequency and induced voltage withstand tests to verify insulation integrity. Additional tests include no-load and load loss measurements, tank pressure and leakage inspections, and functional verification of protective devices like the pressure relief valve, ensuring compliance with all design specifications and operational safety standards.

04 Packing and Shipping

4.1 Packing

This 1000 kVA transformer is packaged in an export – grade detachable steel – edged plywood case. Constructed with multi – layer plywood and reinforced by metal steel strips at edges and joints, it features fork pockets at the bottom for forklift handling. The case is marked with specification and protection labels. It integrates buffering and robustness, effectively protecting the equipment during transportation and enabling convenient on – site unpacking and installation.

4.2 Shipping

Our 1000kVA UL-listed three-phase pad mounted transformer is delivered DDP (China to US). Despite trans-Pacific shipping delays and strict US electrical regulations, we achieve 99% on-time delivery and 0.03% damage rate, cutting your project timeline by 20% – our seamless, compliant delivery outperforms competitors, letting you focus on core operations.
