제품 설명
150kVA 25kV Class 23kV to 480Y/277V Three Phase Pad Mounted Transformer UL Listed

Best for:

23kV medium-voltage distribution, 480Y/277V outdoor power supply, commercial buildings, utility distribution points, and light industrial systems.



Buyer should provide:

kVA, primary voltage, secondary voltage, frequency, vector group, feed type, standard, quantity, destination port, and accessories.



Product Overview

This 150kVA 25kV Class three-phase pad-mounted transformer is designed for 23kV medium-voltage feeder step-down applications where 480Y/277V service is required. It is suitable for commercial buildings, utility distribution points, light industrial facilities, municipal sites and outdoor power systems. The transformer uses a radial-feed pad-mounted layout, 25kV Class live-front primary bushings, 480Y/277V secondary spade terminals, ONAN oil cooling and a NEMA 3R outdoor enclosure. With ANSI C57.12.34 design and 125kV HV BIL insulation level, it supports medium-voltage distribution projects that require clear voltage matching, outdoor installation and defined North American transformer configuration.
