167 kVA Pole Distribution Transformer-14.4/0.6 kV | Canada 2024

Compact and efficient, leading a new era of smart power – Single-phase pole-mounted transformer.

01 General

1.1 Project Description

This 167kVA single phase pole distribution transformer was delivered to Canada in 2024. The rated power of the transformer is 167kV, the primary voltage is 14.4kV and the secondary voltage is 0.6kV. The capacity is larger than the normal one. Designed according to standard CSA C2.2-06. The impedance is 2% with ONAN cooling method.

Pole-mounted transformers are commonly used in urban, rural and commercial loads. It is also suitable for other light industrial and commercial lighting applications.

Our 167 kVA pole distribution transformer was designed with advanced technology and adopts high quality material and components, which result in reliable quality and long operation time.

02 Manufacturing

2.1 Core

Reduced Material Loss: Continuous silicon steel strips reduce material waste and increase manufacturing efficiency. Reduced Eddy Current Losses: Thin layers of silicon steel limit the generation of eddy currents, effectively increasing efficiency. Improved Magnetic Flux Distribution: The uniformity of the core helps achieve a more even magnetic flux distribution, reducing energy loss. Reduced Noise: The continuity of the structure reduces vibrations, making operation quieter. Increased Mechanical Stability and Durability: The stable structure is suited for high loads and harsh environments. Increased Production Efficiency: The production process can be highly automated, reducing costs.

2.2 Winding

Symmetrical Winding Distribution: The structure of the windings is typically simple, with high-voltage and low-voltage windings closely coupled to minimize leakage flux. Compact Design: The windings and core are arranged to achieve a compact size and lightweight design, making them suitable for pole-mounted applications, such as rural distribution networks. Stable Performance: Reliable winding and insulation designs ensure stable voltage transformation and long-term operational safety.

2.3 Tank

The oil tank is typically rectangular or cylindrical in shape and is made of high-quality steel plates welded together. It features excellent strength and sealing properties to withstand internal oil pressure and external environmental stress. he surface of the tank is usually coated with an anti-corrosion layer to resist harsh environmental conditions such as high temperatures, humidity, and pollution, thus extending the transformer’s lifespan.

2.4 Final Assembly

Core and Winding Assembly Install the high-voltage and low-voltage windings onto the core, ensuring insulation and concentricity. Body Installation Place the core and winding assembly into the oil tank. Install leads and insulating bushings, ensuring proper sealing. Filling Transformer Oil Inject filtered transformer oil, ensuring it is clean and free of impurities. Install External Accessories Attach safety valves, oil level gauges, and terminal connections.

03 Testing

1. Ratio Test-Using a transformer turns ratio tester (TTR), perform a ratio test to verify the primary- to-secondary winding ratio. The measured value should be within 0.5% of the voltage ratio indicated on the transformer nameplate. If the transformer is provided with high-voltage taps (or low-voltage taps on step-up/step-down trans- formers having low-voltage ratings above 600 Volts), measure the ratio at each tap position to ensure that each of the ratios is correct. When internal low-voltage windings have been reconfigured by the user as described above in “Reconfiguring the Low-Voltage Internal Con- nections”, the ratio test will confirm that the transformer has the correct output voltage and polarity.

2. Insulation Resistance Test-Perform a 1,000 Volt insulation test (Megger test) to measure the resistance of the insulation between windings and from each winding to ground. Follow the instructions and safety precautions provided by the test equipment manufacturer. Prior to the test, bushings must be thoroughly cleaned with denatured alcohol to remove any moisture or contaminants that could influence the test results. Measured resistance should be at least 1.0 GΩ.
