2.9.2.4
Low-Voltage Cable Compartments
Neutrals shall be provided with fully-insulated bushings. Clamp type cable
terminations, suitable for [copper] [aluminum] conductors entering from
below, shall be provided as necessary.
2.9.2.5
Accessories
**************************************************************************
NOTE: Specify thermometer, liquid level gauge, and
a sampling device only where requested by the Using
Agency.
**************************************************************************
High-voltage warning signs shall be permanently attached to each side of
transformer stations. Voltage warning signs shall comply with IEEE C2.
Copper-faced steel or stainless steel ground connection pads shall be
provided in both the high- and low-voltage compartments. Dial-type
thermometer, liquid-level gauge, and drain valve with built-in sampling
device shall be provided for each transformer station.
Insulated-bushing-type parking stands shall be provided adjacent to each
separable load-break elbow to provide for cable isolation during
sectionalizing operations.
2.9.3
Busways
Busways shall comply with NEMA BU 1 and UL 857 and shall be of the voltage,
phase, and continuous current ratings indicated. Neutrals shall be [full
size] [half size]. Busways shall have short-circuit ratings not less than
the maximum short-circuit currents of associated transformers, assuming
primary sources of infinite capacity. Busways shall be
feeder-low-impedance type and of outdoor or indoor service construction as
suitable to the location. Busways shall be complete with elbows, fittings,
flanges, end-closures, tees, crosses, cable-tap boxes, accessories, and
other devices required for the indicated installation, and shall be
coordinated for connection to the indicated equipment. For wet/damp
locations, bus duct shall be heated, nonventilated enclosure, nonsegregated
phase type in accordance with IEEE C37.23. Detail drawings for busway
supports and bracing shall be submitted in accordance with the detail
drawings portion of paragraph SUBMITTALS and shall indicate that busways
are adequately supported for the seismic forces specified in paragraph
GENERAL REQUIREMENTS (sub-paragraph Service Conditions).
2.9.4
Pad-Mounted, Metal-Enclosed, Switchgear
The switchgear shall be configured with [[2] [_____] incoming compartments
for loop-feed arrangement] [one incoming compartment for radial-feed],
equipped with [air-insulated, load-interrupter switches] [oil-insulated,
load-interrupter switches] [SF6-insulated, load-interrupter switches], as
indicated. The outgoing compartments shall be provided with [fused
disconnects] [non-reclosing vacuum-type interrupters or circuit breakers],
as indicated.
