9.10 Cable and Accessories Storage

The cable manufacturer shall provide any requirements for long-term

storage (approximately 20+ years) of cable on reels such as indoor or

outdoor storage, reel rotation, etc. and for the long-term storage and shelf

life of any terminations or straight splice joints if specified in the bid.

Please refer to Section 12, this document, for the peak high and low

temperatures for the Sacramento area for 2010 through 2016 which would

show the temperature conditions that the spare cable would be subjected

to if stored outdoors. The manufacturer shall provide a separate price for

supplying any equipment necessary for long-term storage of cable as an

option with the bid.

9.11 Cable Design Changes

Following approval by SMUD of the specific design and materials

submitted to SMUD by the supplier, the supplier shall not make changes

in such design or materials without the prior written approval of SMUD.

Any potential changes require submittal of information in accordance with

Section 9, this specification.

10 Testing and Inspection

10.1 Witnessing Production and Testing

SMUD shall have the right to witness any or all production or production

tests. The manufacturer shall notify SMUD at least two weeks prior to any

manufacturing and and/or testing of cable supplied in accordance with

these specifications.

10.2 Cable Tests

10.2.1 Cable Qualification Tests

The manufacturer of the cable shall have successfully passed all

applicable Qualification Tests in accordance with ICEA S-108-720

and AEIC CS9 for the design of cables similar to that proposed for

delivery to SMUD.

10.2.2 Water Penetration Test

Longitudinal Water Penetration Resistance Tests shall be

successfully performed per ICEA T-31-610 or SMUD approved

equivalent standard.

10.2.3 Production Tests

The manufacturer shall perform all factory Production Tests in

accordance with ICEA S-108-720 Part 9. Report data shall be

recorded and kept on file at the manufacturing facility for a minimum

of three years. All test data shall be made available to SMUD upon

request. One copy of completed Production Test Reports performed

in accordance with ICEA S-108-720, and certified by the

manufacturer’s Quality Assurance organization shall be submitted

before or at the time of shipment of the cable. The tests report shall

be sent to SMUD’s specifying engineer listed on purchase

documents.

10.2.4 Cable Acceptance

Cable acceptance and payment for the cable may be affected by

delays in receipt of the production test data.

10.3 Termination Tests (if requested in bid)

The supplied terminations shall meet the applicable testing requirement of

Section 7 of IEEE Std 48.

10.4 Joint Tests (if requested in bid)

The supplied joints shall meet the applicable testing requirement of

Section 7 of IEEE Standard 404.

11 Shipping and Storing

11.1 The manufacturer shall furnish the “spare” cable on non-returnable steel

fluted reels, similar to Class II heavy duty, in accordance with NEMA

Standard No. WC-26. The cable reel dimensions shall not exceed 120

inches on the flange and 82 inches on the reel width unless explicitly

approved otherwise. The reel shall easily accommodate a 5-inch diameter

shaft.

11.2 The “spare” reel barrel dimension shall be adequate for long-term storage

(20+ years) of the cable on the reel without damage. The manufacturer

shall protect the cable by utilizing Class 4 wood lagging in accordance

with NEMA Standard No. WC-26, Section 4, or other SMUD approved

lagging. If the 120-inch diameter by 82-inch wide reels will not

accommodate the specified cable lengths with the wood lagging, the

supplier may request in writing to waive the wood lagging requirement or

recommend use of another reel.

11.3 The manufacturer shall suggest any other method(s) that can be applied

to the cable and reel to prevent deterioration due to moisture, UV light, or

other factors that could degrade the cable over time.

11.4 SMUD will list reel shipping lengths in the purchasing documents. The

tolerance on all defined lengths shall be -0% and +5%. SMUD will not

accept lengths shorter than the values defined.

11.5 The manufacturer shall install a pulling eye on outer end of the cable on

each reel. The manufacturer shall seal the inner cable ends and the

pulling eyes against moisture and water intrusion.

11.6 The manufacturer will provide instructions as to how to re-seal the cable

ends after a section has been removed.

11.7 Cable reel stand. Owing to the anticipated weight of the reel, the

manufacturer shall include in their bid a cable stand capable of

supporting the “spare” reel for long-term (20+ years) storage.
