Okonite The City has implemented a pre-approval process for substitution commodities and services. The commodity approval form can be obtained via email (laura.hermosillo@cityofdenton.com). Supporting documentation or samples must be submitted for review by Purchasing, Engineering, field crews, QAG (Quality Assurance Group), and the manager of DME. Testing may be required and may take substantial time to review. Vendors are encouraged to submit forms and samples for consideration on the next solicitation for similar items. DEVIATIONS TO SPECIFICATION Offeror’s quoting to this specification will indicate any areas where deviations are required by their design and will provide sufficient information to permit full evaluation of their product prior to submission deadlines. This data will reference the appropriate section number and be sent in letter format with their proposal. Any alternate proposal shall be approved by the City of Denton prior to the opening date. Alternates shall not be considered less than 10 days prior to opening date. Approved alternates will be sent back out in an Addendum, for all vendors to know that the alternate is acceptable. Unless specifically noted by offeror as indicated above, all quotations shall meet and include all items as detailed in this specification. SHIPMENT AND DELIVERY A delivery schedule after placing an order is required with the proposal. The delivery lead-time for the Electric Distribution Cables and Substation Control Cables will be a consideration in the evaluation. Orders will be placed as needed. The City cannot take delivery of all materials at one time. CUT TO LENGTH PROGRAM This program requires that the supplier be able to take stock of master reels, and then cut cable/wire to length as requested by the City for deliveries to Denton as requested below. The City would take measurements in the field, and then contact the vendor with the lengths needed. Vendor shall cut the cable to lengths and re-spool to the required reel specifications in the specifications. Delivery shall be made within 72 hours upon receipt of lengths. Cut lengths shall be from 0% to plus 3%. No reel length shall be less than the requested length. The City shall release a minimum of three reels at one time for any cut to length order. The City shall not be charged for any cable remaining on the master reels that are deemed too short for DME use nominally defined as 200 feet or less. The remaining cable material shall remain the property of the vendor. The City will hold undamaged wooden reels that can be returned for the vendor to re-use. The City has limited space available for storage, and can only keep minimal quantities. The vendor must pick up the reels within 5 business days upon notification. The City may request full reels as noted on the proposal page for each specified cable. This will allow the City to have dedicated emergency cable stock on-hand in Denton at all times as well as for specific DME special project use. Reels shall be marked with identification tags with cut length, size of cable, DME reel name and job name. Supplier shall propose the additional price per foot for the cut to length program costs. Liquidated damaged will be incurred for deliveries not meeting the contractually agreed upon delivery timeframe. See Liquidated Damaged for additional information. SAMPLES Offeror’s shall make samples available upon request by the City of Denton, prior to award with no cost to the City.

Copper conductors shall consist of all bare strands or tin coated strands in the outer layer in accordance with ASTM B-3 and ASTM B-496 for Compact Copper Conductors. Manufacturer must utilize and maintain a high quality control process to ensure that the outer conductor dimensions do not vary.

The insulation shall be free from voids, contaminants, gels and agglomerates in accordance with the latest edition of AEIC CS8 or ICEA S-97-682-2013. INSULATION SHIELD: The insulation shield shall be black, thermosetting, semi-conducting material extruded over the insulation and shall be compatible with both the insulation and the copper tape shield. The thickness shall comply with the requirements of the latest edition of AEIC CS8-2013 or ICEA S-97-682-2013. The insulation shield shall be free stripping from the insulation, leaving it free of any significant residue of semi-conducting material.

The outer layer of the insulation shield shall be printed at regular intervals with a warning statement using contrasting color ink. Warning shall state “Semi-conducting” and “Remove when splicing or terminating”. METALLIC SHIELD: The metallic shield shall consist of a bare copper tape helically wrapped over the insulation shield.
