Open, Alley and Bridge Type Transformer
Platforms
Hughes Brothers Standard Transformer Platforms are complete units partially factory assembled for quick and easy installation.
These prefabricated units are economical because no field work is required other than boring the pole holes; there’s no cutting, fitting, waste or costly delays. Complete units can be relocated if necessary, to meet service demands. Wood members are made from select Douglas-fir components, pressure treated with pentachlorophenol.
The following pages show Open, Alley and Bridge type transformer platforms for various pole spacings.
Hughes Brothers Spread Channel Transformer Platforms have side channels which are attached to channels rather than directly to the poles. This allows for greater vertical space under the platform.
The spread-channel type platform has the planks made into removable panels allowing the transformer to be raised vertically through the platform. The panels are easily re-placed in their proper positions.
The same advantages are present in the removal of a transformer. Usually a transformer can be removed without disturbing the adjacent transformers.
Hughes Brothers Transformer Platforms are furnished complete, shipped with all bolts, ready to install. These prefabricated units are economical because no field work is required other than boring the pole holes; there’s no cutting, fitting, waste or costly delays.
Wood parts are made from Douglas-fir, pressure treated with pentachlorophenol. Steel parts are hot dip galvanized.
