Single Phase – Standard Isolation Transformers

Application

transientIsolation transformers should be used on all systems that require grounding on the load. Rex single-phase distribution transformers are ideal for supplying auxiliary lighting circuits from 600 V and lower supplies, and electric heating equipment.

Features

  • General purpose ventilated steel enclosure suitable for indoor, dry locations. After fabrication, all metal is finished in ASA 61 grey power coating suitable for most industrial and commercial installations.
  • Transformers up to 75 kVA capacity may be readily hung on H-columns, walls, shelves or floor mounted to suit each installation. Most units have lifting lugs, conduit Knock-Outs (Kos) and a removable front  cover for convenient access to terminals.
  • Transformers rated above 75 kVA  are suitable for floor or platform mounting and complete with integral lifting lugs and removable front panels for convenient access to terminals.
  • Transformers terminations rated below 330 Amps are supplied with suitable hardware and lugs for cable connection. Terminations above 330 Amps are supplied with terminal pads only.
  • Primary windings have full capacity taps for supply voltage compensations and split secondaries for flexibility.
  • Class 220 insulation used throughout.
