AGENDA TITLE: Specifications and Advertisement for Bids for Padmount Liquid Insulated Vacuum Switchgear
MEETING DATE: January 5, 2000
PREPARED BY: Electric Utility Director
RECOMMENDED ACTION: That the City Council approve the specifications and authorize advertisement
for bids for eleven units of Padmount Liquid Insulated Vacuum Switchgear.
BACKGROUND INFORMATION: Padmount Liquid Insulated Vacuum Switchgear (Pad Switch) is installed
throughout the City's high voltage underground electric distribution system.
The Pad Switches are located along the main underground feeders to
provide sectionalizing points for trouble shooting as well as fuse protection for the branch feeders originating at the
Pad Switches. The City has installed this type of equipment over the years from various manufacturers having
various design concepts including air and oil insulated, expulsion and current limiting fusing, in oil, air or vacuum
switching and mild and stainless steel cabinets. Experience has shown that vacuum switching in a liquid insulating
medium with sectionalizing switches, current limiting fusing and stainless steel cabinets, as specified here, provides
the most efficient, reliable and safest operating environment in addition to essentially being maintenance free
equipment.
These switches will be utilized in developing areas on the west and south side of the City (3), for the Downtown
distribution system reconstruction project (4), for replacement of existing equipment (3) and for inventorylbackup (1).
The replacement switches (3) are for the last part of a project initiated in the previous fiscal period to replace switches
from one manufacturer that are failing and are unreliable. This manufacturer discontinued production of the switch six
years ago and is no longer providing support and/or parts.
