Single Phase Pad Mounted Transformer General:
• General: KERUN manufactures a complete line of single phase residential pad mounted distribution transformers in its KERUN Power™ series product line. They are available in standard ratings and configurations or can be customized to meet specific needs.
• Single-phase transformers are available as ANSI I & II transformers (shown above in order). All of these distribution transformers are oil-insulated, selfcooled, available in loop or radial feed, and are dead-front.
• All of these transformers meet or exceed ANSI®, IEEE® and NEMA® standards.
• The ANSI® and IEEE® Type-1frontplate arrangement allows vertical feed to the primary and secondary bushings. It is ideal for single-phase industrial and residential applications where a wide range of kVAs or heavy cabling is required.
• KERUN offers KERUN Power™ series poly-pads that are usable with most transformers conforming to ANSI® C57.12.25-1990 standard (Type-1 or Type-2).
Single Phase Pad Mounted Transformer Advantage:
• KERUN 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.
• KERUN distribution transformers factories utilize the common design platform giving us best-in-class experience, consistency, and repeatability.
• KERUN utilizes best-in-class manufacturing and quality processes to ensure that our transformers will meet the most stringent requirement.
Single Phase Pad Mounted Transformer Features:
• KERUN oil immersed single phase pad mounted distribution 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.
• KERUN oil filled single phase pad mount 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 Manufacturers:
KERUN engineers have 40 years of experience in the transformer industry and have accumulated a wealth of experience in participating in different projects in various countries. Based on project cooperation cases, KERUN can help you analyze the types of transformers you need in project construction and provide complete power distribution and other solutions.
