50kva Pad Mounted Transformer 12470V/240V Single Phase Distribution
Transformer
WINLEY‘s ’single-phase pad-mounted distribution transformers are
designed per applicable ANSI, IEEE, NEMA and Department of Energy
standards and are built to allow safe and reliable operation in
underground electrical distribution networks. Our transformers are
designed to be installed in radial or loop feed distribution
systems and can be configured to meet specified switching and
protective requirements.
