Three 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.
• Three-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).
3 Phase Pad Mounted Transformer Advantage:
• Strong overload capacity, does not affect the service life .
• Energy saving and environmental protection,Stable operation.
• Three-phase five-column structure, the voltage quality is high, the neutral point does not drift, the.cabinet does not generate heat, the noise is low, and the lightning protection performance is good.
Residential Pad Mounted Transformer Applications::
• Padmounted transformer usually installd at streets, parks, hotels, countryside, residential or commercial areas.
Three Phase Pad Mounted Transformers Design:
• Compartmental available in live-front or dead-front design.
• Critical load designed with special attention to surge protection.
• Hardened data center designed with special attention to surge protection, providing superior.
• performance under the most stressful electrical environments.
• Solar specifically designed for Solar Photovoltaic generator step-up (GSU) applications.
• Vacuum fault interrupter combines both voltage transformation and either transformer or loop.
• overcurrent protection in one space-saving, money-saving package.
• Can be located near or inside buildings for greater flexibility and savings.
Ground Pad Mounted Transformer Transport Packaging:
Outdoor pad mounted distribution transformers are packed with plastic cloth, and the corners are protected with pearl cotton and wrapped with winding film.
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.
