MVS/MSV2 product description
The MVS standard structures for 5 kV and 15 kV switchgear is
33 .00 to 48 .00 inches wide, 90 .38 inches high (indoor), 98 .88 inches high (outdoor), with varying depths . The standard structures for
27 kV and 38 kV switchgear is 48 .00 to 54 .00 inches wide, 101 .50 or 127 .00 inches high (indoor), 110 .00 or 135 .50 inches high (outdoor), with varying depths . Vertical sections are freestanding, close coupled to transformers and bolted together forming lineups .
WLI product description
The WLI (Load Interrupter) switch structure was offered in both 33 .00-inch and 36 .00-inch wide enclosures in the 5 kV and 15 kV ratings . Both designs used vertical sections that were freestanding, close coupled to transformers, and bolted together in lineups . WLI was offered in 5 kV , 15 kV , 25 kV , and 38 kV voltage ratings using 600 A and 1200 A switches .
