SecoGear Switchgear Concepts and Basic Configurations

• SecoGear utilizes modular construction resulting in one
basic vertical section size, simplifying system planning
and increasing installation savings
• SecoGear features four-high auxiliary arrangements,
providing additional flexibility and use of floor space
• SecoGear allows for intermixing auxiliary and a breaker
compartment in the same vertical section
Certain elements in the switchgear application procedure
are affected by these fundamental design features. Cubicle
stacking, cabling direction, and VT & CPT compartment
considerations are key when translating the one-line
diagram into a valid arrangement of switchgear cubicles,
auxiliary rollouts, and bus connections in a lineup. These
application considerations are necessary as a result of the
equipment design. A brief illustration of SecoGear
switchgear design concepts is provided to assist in
understanding.
