3750kVA Three Phase Pad Mounted Distribution Transformer 12870V To 480Y/277V ANSI IEEE Standards
Product Overview
This 3750kVA three-phase pad-mounted transformer is designed for North American medium-voltage distribution applications, including utility distribution, commercial complexes, industrial facilities, campus power systems, and outdoor projects requiring 12.87kV to 480Y/277 V voltage conversion. Built in accordance with ANSI C57.12.34, it features 7-step high-voltage tap adjustment, 95 kV / 30 kV BIL insulation level, and integrated fuse, arrester, and loadbreak switch configuration. These specifications support project specification review, site voltage matching, insulation coordination, and outdoor equipment protection, while the integrated protection and switching layout helps simplify installation, field operation, and routine maintenance.
