SECTION 16126 - POWER CABLE INSTALLATION METHODS

PART 1 - EXECUTION

1.1 GENERAL

A. Install electric conductors and cables as indicated, in compliance with manufacturer's written instructions,

applicable requirements of NEC and NECA's "Standards of Installation"", and in accordance with

recognized industry practices.

B. Cables shall not be pulled into plastic conduit until all conduit joints made using plastic conduit cement

have been allowed to dry for at least ½ hour.

C. When pulling cables into conduit, the pulling line used shall have a safe working load rating (minimum)

equal to the maximum allowable pulling line tensions for the type and size of cables being pulled as

recommended by the manufacturer. Cables shall be pulled into conduit with a pulling eye attached to the

cable conductor or a pulling grip placed over the cable sheath, insulation or jacket.

D. When cables are pulled into straight conduit runs, the pulling line tension shall not exceed the values shown

in the manufacturer's shop drawings.

E. When cables are pulled into conduit runs including bends or sweeps, the maximum pulling line tension

shall not exceed 300 times the radius of curvature of the bend or sweep with the smallest radius expressed

in feet.

1.2 CABLES PULLING IN CONDUIT

A. Whenever possible, pull cables so that bends in the conduit into which the cables are to be pulled are

nearest to the feed-in end. This will result in minimum tension on the cables.

B. On long pulls, the pull-out location should be rigged whenever possible, so that an adequate amount of

cable for splicing and racking may be pulled into the manhole without the necessity of taking hitches on the

cable sheath or jacket.

C. In highly congested switchgear or where cables must be bent sharply to permit pulling, use a feed-in tube

for pulling in cables. This will reduce pulling tensions and prevent damage to the cables being pulled and

to other adjacent cables.

D. Before making a pull, conduits should be clear and free of dirt, rocks, etc.

E. When pulling three single conductor cables in one conduit, consideration should be given to the possibility

of the cables jamming, particularly at bends. This possibility occurs when the sum of the outside diameters

of the three cables approximately equals the inside diameter of the conduit they are to be pulled into. When

the possibility of jamming exists, pulling tension should be continuously monitored to ensure that damage

to the cables, should they jam, will be kept to a minimum.

F. Wire rope shall be used to pull cables in nonmetallic conduits unless all bends in the conduits are

constructed using a bent length of steel conduit or steel conduit elbows. Installation methods which

eliminate damaged to the conduit and associated elbows shall be used.

G. Do not pull cable into duct or conduit until factory test reports of cable have been approved.

H. Cables may be pulled by direct attachment to conductors or by use of basket weave pulling grip applied

over cables. Attachment to pulling device shall be made through approved swivel connection. Cable may






be pulled by using basket weave pulling grip, provided the pulling force does not exceed limits

recommended by manufacturer; if pulling more than one cable, bind them together with friction tape before

applying the grip. For long pulls requiring heavy pulling force, use pulling eyes attached to conductors.

I. Do not exceed manufacturer's recommendations for maximum allowable pulling tension, side wall

pressure, and minimum allowable bending radius. In all cases, pulling tension applied to the conductors

shall be limited to 0.008 lbs. per circular mil of conductor cross-section area.

J. Pull in cable from the end having the sharpest bend; i.e. bend shall be closest to reel. Keep pulling tension

to minimum by liberal use of lubricant, and turning of reel, and slack feeding of cable into duct entrance.

Employ not less than one man at reel and one in pullhole during this operation.

K. For training of cables, minimum bend radius to inner surface of cable shall be 15 times cable diameter.

L. Where cable is pulled under tension over sheaves, conduit bends, or other curved surfaces, make minimum

bend radius 50% greater than specified above for training.

M. Use only wire and cable pulling compound recommended by the specific cable manufacturer, and which is

listed by UL. Pulling compound shall be used liberally (at both ends of the pull) to minimize any damage

to the conduit system and cables and to keep pulling tensions to a minimum.

N. Seal all cable ends unless splicing is to be done immediately.

O. Train and support all cables in manholes, pullholes, concrete trenches, and similar locations by cable racks

and secure to rack insulators with nylon cord and self-locking nylon cable ties.

1.3 AFTER INSTALLATION TESTING

A. After installation and before the operating test on connection to the existing system, the cable shall be given

a high potential test.

B. Test all cable per ICEA Standards. Notify Owner's representative of proposed date of test sufficiently in

advance so that arrangements can be made for the Engineer and the Owner's personnel to witness the test.

C. Test the conductor for continuity with all equipment disconnected.

D. Submit three (3) copies of test, properly labeled, to the Engineer of review. Include all necessary test

information such as cable system identification, ambient temperature, weather conditions, current, voltage,

cable length, size, etc.

1.4 CABLE PHASING

A. Each cable shall be properly "phased" to assure proper connection to the system.

B. Supply all equipment needed to make phasing checks.

C. Notify the Engineer and the Owner sufficiently in advance of making phase checks to allow for

arrangements to be made for the witnessing of the tests.

D. Make necessary changes to cable connection points, as determined by phasing checks, and reverify phasing

after any cable changes.
