Mild steel tank with welded lifting lugs and hanger brackets for direct to pole mounting. Spin top bushings for either cover or side wall mount. Provide you with reliable and cost effective transformer products matched to your system requirements.

The distribution transformers available for use for various applications as shown include pole type figs. A dual voltage switch permits use of the same transformer on. These harmonics can cause interference in nearby communication circuits as well as other assorted power quality problems. Figure 4 wye wye transformer connections diagram click to expand diagram one problem inherent to wye wye transformers is the propagation of third harmonic currents and voltages.

I have a question regarding distribution transformer mounted on a pole neighborhood how are more than one house wired to a distribution transformer on the pole. The externally operated tap changer is a single phase five position design for de energized operation. Some details on this would be great. 15 5 and submersible fig.

A single phase as is the case in one pole mounted distribution transformer as well uses the neutral from a three phase system. Standard features meets or exceeds current rus nema and ansi standards c57 12 00 ansi c57 12 20 as applicable. Bushing for cover mounting.
