specification in accordance with the procedures given in paragraph 9.13 of ICEA S-94-649-2000. The apparent
discharge characteristic shall be reported on an x-y plot. Partial discharge of each shipping reel of completed
cable shall not exceed five (5) picocoulombs during any portion of the partial discharge test specified in ICEA S-
94-649-2000.
5 PREPARATION FOR DELIVERY
Packaging and marking of the articles procured under this specification shall be in accordance with AEIC No.
CS8, section J and the following requirements. Nails used in reels shall be galvanized, resin coated, or self -
clenching and set so they cannot work free and damage the cable. All reels shall be inspected for protruding
nails and, if required, corrective action taken before cable is put on the reel.
5.1 Each reel shall be protected with a covering in conformance with NEMA WC-26 Class 2 as
approved in writing by Fort Collins Utilities, Electric Department, Engineering Standards. The covering
shall be banded in place with a minimum of two 1/2" steel bands. Reels shall be shipped on open -bed
truck(s) with reels in the upright position; i.e., on flanges, and blocked to prevent movement during
shipping.

1 SCOPE
This specification establishes the minimum requirements for two -conductor insulated, shielded, and jacketed
concentric -neutral underground distribution cable, insulated with a thermosetting dielectric based on cross -
linked polyethylene (XLPE). Cable described herein is intended for 60 Hz, single and three-phase applications
in wet or dry locations in conduit, underground duct systems, direct buried and aerial installations in open air in
sunlight.
2 APPLICABLE DOCUMENTS
The following documents of the issue shown form a part of this specification to the extent specified herein. In
those cases when the document is not dated, the latest issue in effect on the date of invitation for bids shall form

3.1.4 Guarantee
Seller warrants that cable furnished under these specifications is free of defects in material and workmanship,
that it has been manufactured and tested in accordance with these specifications and that the results of said
tests comply with the requirements of said specifications. Seller agrees to provide replacement product for (i)
any cable found defective in material or workmanship regardless of the age of the cable, or (ii) any cable failing
during normal and proper use within one year of the date of placing in service. The date of placing in service is
the date on which operating voltage is first applied. All replacements shall be made free of charge, f.o.b. the
delivery point called for in the original order. The requirements of paragraph 4.1 of this specification, requiring
independent testing laboratory certification, shall in no way limit the liability of the vendor regarding the
guarantee.
