Technical Specifications
Supply of Optical Ground Wire (OPGW) Transmission Conductor and Accessories
A. PURPOSE
The City of Denton is providing information that will allow prospective suppliers to prepare
submissions to supply of Electric Utility Polymer Insulators. The products will be received and
distributed through a centralized distribution center located at 901B Texas Street, Denton, TX
76209. Orders will be placed as needed over the contract term.
Denton Municipal Electric (DME) has transmission line projects approved in its five year Capital
Improvement Plan that will require installation of Optical Ground Wire (OPGW). For perspective,
DME has plans to complete projects for approximately 15 miles of transmission line that will require
OPGW installation over the next five years. This specification provides the information necessary
to allow prospective suppliers to prepare proposals for supplying and delivering 72 and 144 fiber
optical ground wire (OPGW) and associated hardware to be used as the static conductor on the
transmission lines. DME has selected the AFL OPGW conductor described in AFL DNO-8168
and DNO-10583 as its standard for this purpose. Designs have been developed using the
mechanical properties of this OPGW. The AFL DNO-8168 and DNO-10583 information is
included as the final pages of this specification. Only AFL OPGW and accessories are acceptable.
The City of Denton is seeking an annually renewable, unit price agreement for furnishing the
OPGW. It is intended that the agreement include a fair and equitable price adjustment mechanism
for changes in material and delivery costs over time. OPGW will be ordered to accommodate
project construction schedules.
B. REEL AND REEL LENGTHS
It is expected that the majority of the orders for OPGW will be requested to be placed on standard
wood reels. Cut to order lengths will be necessary for most projects. To the extent feasible, shorter
lengths needed will be combined to make reasonable reel lengths. The standard wood reels shown
on the DNO-8168 and DNO-10583 specification will be used.
C. SUBMISSIONS
Submissions shall be provided using the Exhibit 1, with supporting documentation as required.
Additional information clarifying the supplier’s product may be attached to their submission.
Pricing shall include all costs to deliver goods as specified in this specification. Any special fees
or commissions, and all freight for delivery to the City of Denton Warehouse and unloading costs
must be included in the quoted price. Item pricing shall be mutually exclusive, thus the City of
Denton reserves the right to choose the best valued item from different vendors.
D. QUALITY CONTROL
The manufacturer shall be responsible for the quality control of the manufacturing processes to
assure that all requirements of these specifications are met. However, the City reserves the right
to observe, to inspect and to require additional quality control investigations, either by its personnel
or an independently employed quality control investigator, at any or all stages of fabrication at the
IFB 6551– Exhibit 3 Page 3 of 13
manufacturer’s facilities. Failure to adequately maintain fabrication and quality of fabrication until
completion shall be grounds for cancellation of the order or any part thereof.
Field failure or field repairs required due to quality control failures or manufacturing procedures
shall be the responsibility of the manufacturer.
E. WRITTEN WARRANTY and GUARANTEES
Written guarantees shall include any limitations as to the nature of failure or time limitations. The
guarantee shall begin upon receipt of the accepted units, not on the date of manufacture.
Guarantees shall indicate whether or not it is made on a full replacement basis or a prorated basis
and if prorated then what are the terms. Manufacturer/supplier guarantees that the goods furnished
under this specification are of high quality and agrees to replace any goods found to be defective
during inspection, installation, or service for a minimum period of 12 months after unit is delivered
to Denton. All replacements by the manufacturer/supplier shall be free of charge F.O.B. at the
same delivery point called for in the original order. Replacements must be handled in a
professional and timely manner and in no case shall a replacement unit take longer than 60 days
to arrive in Denton after first being submitted for replacement.
Respondent guarantees that all products quoted and furnished under this agreement will be
accepted at any normally used United States approved repair and warranty shop should one be
available for the manufacturer’s product quoted. The City of Denton will not accept a
manufacturer’s product that was rejected or substandard and then sold to a broker for either resale
or scrap that would not be fully warranted by the original manufacturer.
The respondent must be an approved distributor by the manufacturer of these products, and is
authorized to sell the products to the City of Denton. The respondent also guarantees that the City
will be represented by the Manufacturer, should an issue arise, and that all manufacturer’s
warranties will be in effect for the life of the contract.
F. SPECIAL DELIVERY REQUIREMENTS
Deliveries shall be made between 8:00 AM -3:00 PM Monday through Friday, excluding holidays
