Special Application for Vista®

“Mobile” Heavy-Duty Vista® Designed to MIL Spec E-810

Manhole Style Vista®

Designed in conjunction with branches of the US Military, Mobile Vista UDS is rugged enough to withstand air transport to provisional military bases . . . and can be used for temporary or permanent electrical installations. Vista is small and lightweight, so it’s ideally suited for airlifting.

Mobile Vista passed the MIL Spec E-810 20-hour shaker-table vibration test, verifying that stacked units could withstand 10,000 miles of travel aboard aircraft, and it passed tests verifying that switchgear performance is not affected after the gear has been subjected to low pressure at an altitude of 40,000 feet. Mobile Vista can be stacked two-high to save space aboard airplanes and in storage.

To comply with the stringent E-810 specifications, the Vista UDS enclosure was completely redesigned and outfitted with an integral steel skid. The skid and enclosure frame utilize heavy-duty steel I-beams and channels. Four alignment pins at the top corners of the enclosure facilitate stacking of the units. Stacked units are lifted by eyebolts on the skid frame. Channels at the bottom allow for forklift handling and reinforced tabs at the lower corners of the skid allow the gear to be dragged along the ground. Turnbuckles, attached to eyebolts on front and rear sides of the skid, hold stacked units together during transport. Plates, attached to the floor of the enclosure, protect the switchgear during transport and storage and can be removed for cable entry while the gear is in use.

Even after the numerous design changes listed above, all the unique features of Vista UDS were retained. Mobile Vista has a 600-ampere continuous current rating and 16-kA short-circuit and fault-interrupting capability. Each unit includes two load-interrupter switch ways and four fault-interrupter ways. Optional voltage indicators are also included.
