FEDERAL PACIFICâ„¢ T48LH2Y-15 Enclosed Transformer, Encapsulated Transformer, 480 V Primary, 208Y/120 V Secondary, 15000 V Power, 60 Hz Frequency, Three ph, Lugs/Bolt Down Terminals Connection, Floor Mounting, 220 Insulation, 150 deg C deg C, Aluminum Housing Material, 29 H x 17.125 W x 19.375 D in Dimensions

• Federal Pacific ventilated dry-type transformers incorporates wire and or strip wound coils in a barrel wound configuration. Horizontal and vertical spacers are strategically positioned in the windings to brace the winging layers and allow maximum ventilation. The electrical grade core steel is arranged in a construction designed to accommodate the coils
• The core and coil assembly is anchored to the enclosure through a vibration dampening system to reduce noise levels. Units through 600 kBA are provided with neoprene isolating pads while larger units are furnished with three layer rubber and cork pads. A flexible grounding conductor is installed between the core and coil assembly and the transformer enclosure
• Enclosures are rigidly braced and covers are fastened with slotted hex head screws for ease of removal. A rugged steel base supported by mounting feet opened outward provides safe handling with a fork lift and easy attachment to mounting pad
• Front accessible wiring compartments are approved for 90°C cable. Terminals are sized to carry the full current capacity of the transformers
• To attain UL listing, it was necessary to complete an accelerated aging test as specified by Underwriters Laboratories, Inc. This insulation system was subjected to a series of exposures to heat, vibration, moisture, and dielectric tests. As a proven system, this insulation system has received from Underwriters Laboratories, Inc. a recognized 200°C continuous rating. This total temperature of 220°C is derived from the average conductor temperature rise of 150°, hotspot temperature gradient of 30°C and an ambient temperature of 30°C
• The major components that allow for this 220°C rating are Nomex® paper, resin-glass laminates, silicon rubber, and polyester varnish. This combination of materials and the care taken in construction and workmanship, not only give these transformers a long operating life, but helps insure their quiet operation
• The design features of Federal Pacific transformers assures versatile, economical, and reliable distribution of power. All transformers are fully tested to insure trouble-free installation and operation. The unique combination of ratings makes the FH family suitable for a wide variety of applications
