61 -- PROTOTYPE HI-VOLTAGE CABLE SOL 001-DK-99 DUE 063099 POC Deborah Kimbrell (702) 295-2114 -- Fax (702) 295-1702 E-MAIL: kimbreda@nv.doe.gov, kimbreda@nv.doe.gov. Sources Sought/Request for Information: Bechtel Nevada is seeking sources that can provide 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 the cable shall be in accordance with NEMA WC-26 on on-returnable reels with class 3 protection. The cable reels shall be identified with the following: reel tags supplied by Bechtel Nevada, DOE-NF-RF-82/Prototype and purchase order number stenciled using a white seal coat background and black lettering paint which is weather resistant for markings on the reel. Product evaluation per paragraph 2 of the Specification for a Hi-Voltage Coaxial Cable shown below, 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 tests is the basis for payment. 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 product 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 the information to kimbreda@nv.doe.gov. Request all information be provided no later than June 30, 1999. Posted 05/27/99 (W-SN336846). (0147)
