Single Phase Pad 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 Pad Mounted Transformer Applications:

· Sourceway’s single phase pad mounted transformer include Loop feed type and Radial feed type. They are mounted ground and under ground. These transformers typically service urban and rural residential and commercial loads.

· Sourceway’s single phase pad mounted transformer are used in underground industrial and residential power distribution systems, for Industrial, Commercial, Institutional and Residential areas, where safety is prime concern.

Single Phase Pad 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
