kimbreda@nv.doe.gov, kimbreda@nv.doe.gov. Sources Sought/Request for
Information: Bechtel Nevada is seeking sources that can provide a
Prototype Hi-voltage continually gas blocked cable as follows:
Requirement is for 1,000 feet of a prototype hi-voltage cable in
accordance with the below specification DOE-NV-RF-82/Prototype. The
cable shall be supplied in lengths of 500 feet +/-10%. The cable shall
be continuous and free from factory splices. Delivery requirements:
Delivery to the Nevada Test Site within 14 weeks from date of award.
Manufacturer's quality program shall conform to U.S. Department of
Energy Specification DOE-NV-STD-1, Revision 5, approved 7/10/90.
(Furnished upon request). Packaging of this cable shall be in
accordance with NEMA WC-26 on non-returnable reels with class 3
protection. The cable reels shall be identified with the following:
Reel tags supplied by Bechtel Nevada, DOE-NV-RF-82/Prototype and
purchase order number stenciled using a white seal coat background and
black lettering paint which is weather resistant formarkings on the
reel. Product evaluation per paragraph 2 of the below specification is
required for this item. The testing will be performed by the Bechtel
Nevada Cable RD&T Group at the Nevada Test Site and passing these test
is the basis for payments. SPECIFICATION FOR A HI-VOLTAGE COAXIAL
CABLE PROTYPE DOE-NV-RF-82/PROTOTYPE JUNE 25, 1998 A gas blocked
hi-voltage coaxial cable suitable for use with the Scandi Flash x-ray
system. 1. GENERAL DESCRIPTION: This specification contains
requirements for a Hi-Voltage cable consisting of a solid bare copper
center conductor, a semiconductive layer, a solid polyethylene
dielectric, a semiconductive layer, a single tinned copper braid, and
a black PVC jacket. (DRAWING TO BE FURNISHED UPON REQUEST) 2. SPECIFIC
REQUIREMENTS: 2.1 Eccentricity: The solid bare center conductor shall
not have an eccentricity exceeding 2.5% in relation with the solid
polyethylene dielectric. The following formula is to be used for this
measurement: % Eccentricity = Tmax—Tmin X 100 Measured diamenter
of core 2.1.1 Method: The method for measuring requires removing the
outer components of the cable down to the polyethylene dielectric core.
The end of the specimen shall be cut squarely and carefully deburred.
The eccentricity in terms of displacement shall be measured with a
comparator, or any other instrument capable of yielding a resolution of
at least 0.0005 inch. Measure the maximum and the minimum distance from
the center conductor to the outer edge of the dielectric. The thickest
(Tmax) and the thinnest (Tmin) shall then be used to compute the
displacement. 2.2 Gas Block: The center conductor shall be gas blocked.
A ten foot length of the four components making up the core: (Center
conductor, semiconductive layer, solid polyethylene dielectric, and
semiconductive layer) shall not leak when subjected to a pressure of
125 psig applied to this cross-sectional surface area for a period of
6 hours. This test shall be performed by the buyers Cable RD&T group
and failure to pass this test shall be cause to reject the entire lot.
3. DETAILS OF CONSTRUCTION: 3.1 Center Conductor: The 4 AWG center
conductor shall be solid bare soft copper wire in accordance with ASTM
B-3. The outer diameter shall be 0.2043 nominal and 0.2020 minimum.
(Ref: UL 1581) 3.2 Semiconductive Layer: A layer of semiconductive
polyethylene shall be extruded over and bonded to the solid bare copper
center conductor. The thickness shall be 0.060 +/- 0.005 inches.
Nominal Diameter 0.322 inches. 3.3 Dielectric: The dielectric material
shall be solid polyethylene per ASTM D 1248 as IA5, Grade E4 designed
for power insulation of 5 KV and higher. Nominal Diameter 1.250
inches. 3.4 Semiconductive layer: A semiconductive layer shall be
extruded over the dielectric core. This layer shall bond to the core
sufficiently to pass the gas pressure test described in para. 2.2. The
thickness shall be 0.060 +/- 0.005 inches. Nominal Diameter 1.320
inches 3.5 Outer Conductor: The outer conductor shall consist of a
single braid made up of No. 30 AWG tinned soft copper wires in
accordance with ASTM B-33. The braid shall be applied over the
semiconductive layer using a 36 or 48 carrier braider, a braid angle of
32 to 45 degrees and provide a minimum coverage of 85 percent. Nominal
Diameter 1.370 inches 3.6 Outer Sheath: A sheath of black PVC, 0.065
+/- 0.010 inches thick, shall be tubed over the braid to provide a
smooth continuous sheath over the outer conductor. Care should be
exercised so that the sheath does not adhere to the braided outer
conductor. It is permissible to provide a thin cigarette folded paper
layer between the outer sheath and the outer conductor at the
manufacturers discretion to prevent adhesion between the braid and
sheath. Nominal Diameter 1.500 inches 3.7 Cable Identification: The
following identification shall be marked on the cables outer sheath,
using ink of a contrasting color. Characters shall be at least 1/8 inch
high and at intervals of not more then 5 feet. DOE-NV-RF-82,
Manufacturer=s Name, Month and Year of Manufacture Request all
interested parties submit brochures, capability statements or other
descriptive literature, which provides sufficient detail to enable
preliminary functional evaluation. Information should be faxed to the
attention of Deborah Kimbrell @ (702) 295-2088 or e-mail information to
kimbreda@nv.doe.gov. Request all information be provided no later than
June 30, 1999. Posted 05/28/99 (W-SN336983). (0148) Loren Data Corp. http://www.ld.com (SYN# 0262 19990602\61-0008.SOL)
