<p>Electrical cabinet enclosures rely upon complex corner pieces for construction, which is mostly pre-assembled and transported installation sites. Cost of fabrication of complex profiles and corner pieces and of transportation and handling the pre-assembled structures are the drawbacks of the prior works reported. The present invention, employing two- dimensional components, not only removes the drawbacks of the prior works, but makes the fabrication, handling, transportation of two-dimensional components much simpler and require much less manpower. It relies upon a channel, entirely fabricated of a single sheet, as the vertical member of the framework which facilitates three-depth wise and three-width wise channel connections for internal mounting of components.</p> |
