Drawings

Trayer switchgear designs are described by the application, i.e. Submersible, Vaultmount, or Padmount – Single side access, or Padmount – Double side access. Within these categories the drawings are defined by their shape; Round, Square or Rectangular, and then by the required number of three-phase ways. Note also the categories for Automation and SCADA.  Trayer drawing numbers are related to the date the drawing was created and not to the Trayer catalog number of the unit.  Trayer has a vast library of designs created over the past 50+ years. We can modify and alter designs to your requirements and application, please contact us.
