Pad Mounted Transformer

Three-phase pad-mounted transformers are compact power centers for commercial or industrial applications. With proper design selection, they can be located near or inside buildings for greater flexibility and savings.

TYPE: Three-Phase, 50 or 60 Hz, 65 (55/65 Optional)

LIQUID TYPE: Mineral Oil or Envirotemp FR3 Fluid

KVA: 45-7500

PRIMARY VOLTAGE: 2400-43, 800 V (250kV BIL) With or Without Taps, Delta or Wye Connected, Dual Voltages Available

SECONDARY VOLTAGE: 208Y/120 V to 24, 940 V

Three-phase pad-mounted compartmental type distribution transformers are designed for indoor or outdoor locations. Unobtrusive construction allows them to be installed in locations exposed to public view like schools, shopping centers and industrial sites. A wide array of configurations and accessories are available to meet a broad range of application demands.
