Oil Immersed 250kVA Single Phase Pole Mounted Distribution Transformer


Product Description

Oil Filled Hermetically Sealed Three Phase Distribution Transformer General:

• Single-phase transformers are commonly used transformers for circuit power distribution. In the distribution network with decentralized power supply, the single-phase transformer has great advantages as a distribution transformer. It adopts a high-efficiency and energy-saving coil core structure design, a fully sealed structure, strong overload capacity, high reliability in continuous operation, and simple maintenance.

Single phase Pole Mounted Transformer Advantage:

• Sourceway utilizes a focus factory concept which leads to a great experience in specific products giving a very high level of consistency in design, manufacture, and test

• Sourceway’s distribution transformers factories utilize the common design platform giving us best-in-class experience, consistency, and repeatability

• Sourceway utilizes best-in-class manufacturing and quality processes to ensure that our transformers will meet the most stringent requirement

Single phase Pole Mounted Transformer Applications:

• Sourceway’s pole-mounted single phase distribution transformers are mounted above ground on poles. These transformers typically service urban and rural residential and commercial loads. Others are light industrial and commercial lighting applications.

• ANSI pole-mounted transformers are available in a continuously self-protected (CSP) version from continuous overload and network protection from transformer faults.

• These transformers are designed for application conditions typically encountered in electric utility distribution systems.

Single phase Pole Mounted Transformer Transport Packaging:

• Single-phase transformers are packaged in three ways: wooden pallets, wooden frames, and wooden boxes.

• We generally use wooden box packaging, which can effectively protect the transformer during transportation

•  Avoid collisions and keep the shape of the transformer intact

• Avoid corrosion, rust, etc. caused by environmental factors

Single phase Pole Mounted Transformer In a 40-foot cabinet:

• A single-phase transformer with a capacity below 50kva can be equipped with 60 units;

• 75kVA single-phase transformer can be equipped with 48 units;

• 100 kVA single-phase transformer can be equipped with 36 units;

• 167 kVA single-phase transformer can be equipped with 21 units.
