832.3Construction.

A.General .

Transport and unreel electric cable from a cable trailer. Do not lay reels on the ground to remove wire or cable.

B.Pulling Cable or Wire Through Conduit, Mast Arms, Traffic Poles, Lighting Poles, Junction Wells,

and Cabinet.

1.Manual Pulling.

a.Required for conduit sizes of 1 1/2 -inches or less.

b.The Department prefers manual pulling for all other sizes. The Department will allow use of a

mechanical puller if the engineer determines that manual pulling is not feasible.

2.A dynamometer is required when pulling cable or wire mechanically.

3.Use a short piece of material as a strain release element that will part if the strain exceeds the

amount specified below between the pulling grip and the pulling medium, unless otherwise directed by the engineer:

a.150-pounds for pulls up through a 12 pair communications cable; and

b.300-pounds for larger cables.

4.The engineer may deem a cable or wire unacceptable if it is:

a.Pulled into a conduit without the use of a pulling grip.

b.Pulled into a conduit without the use of a strain release element.

c.Pulled using methods which may have, or did result, in pulling forces in excess of strain release

material.

d.Pulled in excess of the 150 -pound or 300 -pound pulling limits.

5.Placing Cable or Wire in Existing Conduit.

a.Use pulling lubricant recommended by the cable manufacturer.

b.Pull cable or wire di rectly from reels into the conduit or pull the required length of cable fully

off the reel and then pull into the conduit. ELECTRIC AND ITMS CABLE AND SPLICING SECTION 832

488 c. Arrange the cables in a straight lay to avoid damaging insulation and to avoid twists or kinks.

d.Protect the cable from moisture during placement.

e.Seal cable ends using rubber tape and paint with a sealing type of waterproof compound until

final splicing.

6.Feed cables by hand into the conduit.

7.Use a sleeve when additional radius is required to prevent damage to the cable or wire.

8.Start underground cable runs at 1 terminal point, and continue without splices, to the final

terminal point except for a home run cable to a loop detector wire. Do not splice emergency preemption cable in any application.

9.Leave and arrange additional cable and wire in a neat and orderly manner as follows:

a.Leave 6 -feet of copper cable supported on cable rack assemblies when pulled through

junction wells.

b.Leave 6 -feet of cable neatly arranged and laced with cable ties, at the control box and at splice

locations.

10.In conduits with existing cables, provide a blunt terminal on the leading end of a fishing device

to avoid damaging or entanglement with existing cables or wires. The Department will not allow bending or taping the end of the fishing device instead of using the blunt end terminal.

11.When pulling 2 or more cables into a conduit, pull cables in together, parallel to each other

using a pulling head.

12.Wrap phase legs circumferentially and in sequence around the neutral wires.

13.Leave 2 feet of slack for lighting cables in lighting transformer base.

For lighting cables, seal all conduit ends after cable placement in accordance with Section 831 - Conduit. Traffic signal conduits do not require duct sealant.

C.Overhead on Pole Span Wire.

1.Do not splice the electrical cable at the top of the pole. Continue the electrical cable onto the

span wire to be taped.

2.Leave a drip loop in the electrical cable to prevent water from running along the cable and into

the steel pole.

3.Install the electrical cable on the underside of the span wire with no crossover or wraps around

the span wire.

4.Wrap the electrical tape at least 6 times around the span or cable wire every 12- inches to 14-

inches.

5.Pull the electrical cable tight leaving no kinks.

6.Wrap the plastic tape tight around the span wire.

7.Leave a 36 -inch long loop of signal cable at each signal head.

D.Splicing.

1.Traffic Control Cable and Single Conductor Stranded Wire.

ELECTRIC AND ITMS CABLE AND SPLICING SECTION 832

489 a. Only splice underground traffic control cable where loop detector wire and the home -run cable meet. Do not splice cables in junction wells or conduits.

b.The Department will only allow traffic signal cable splices in pole hand -holes, transformer

bases, or on span wire at the signal head.

c.Use rubber tape to seal the cable ends in control boxes and at all splice locations after cable

placement pending splicing. Paint cable ends with a sealing type of waterproof compound.

d.Identify the circuit number of all cables and wires using color coded tape attached to each of

the cables and wires in the control box and at all splice locations.

e.Secure the color -coded tape to the cable or wire with nylon cable ties.

f.Redo faulty splices within 90 calendar days of installation.

g.Expose 1/2 -inch of copper wire for splicing by removing the insulation.

h.Ensure that the copper conductor, in wires not planned for splicing, does not extend beyond

the insulation.

i.Connect each conductor planned for splicing, then return all conductors (both used and

unused) to their original configuration before the insulation was removed and then seal in accordance with Section 1074.

j.Do not allow individual cables to extend beyond the splice of the last signal head for each

signal phase.

k.Splice shielded aluminum cable (home -run cable) with the loop detector wire in a junction

well only. Do not splice the home -run cable outside of the junction well.

l.Overhead Wire.

i.Place conductors planned for electrical connection side by side with the exposed copper

aligned. ii. Twist the copper clockwise with pliers until a good mechanical connection is achieved. iii. Install and hand tighten a wire nut. iv. If necessary to cover all the copper, minor trimming is allowed.

v.The copper splice is 5/16 -inch long when trimmed.

vi. Ensure that no insulation is caught up in the copper area of the splice. vii. Ensure that the splice is kept dry.

m.Butt Splice Cable Termination.

i.Remove the sheath of each cable as necessary.

ii. Prepare the splice for taping after joining all conductors. iii. Place the cables in a butt position and position all wires and wire nuts to ensure that no shorts exist and that the splice area is reduced to as small a diameter as possible. iv. Begin taping with rubber tape 2 -inches over the intact sheath.

v.Wrap the tape around the splice proceeding toward the other cable overlapping half of the

tape width until reaching a point 2 -inches on the other cable sheath. vi. Repeat taping in the other direction starting 1 tape width wider than the previous wrap. ELECTRIC AND ITMS CABLE AND SPLICING SECTION 832

490 vii. Increase overlapping where necessary to cover all areas of the splice. viii. Place at least 4 layers of rubber tape, 2 fully overlapped passes deep for every area of the splice. ix. Cover the rubber tape with plastic tape applied in the same fashion.

n.Taps or Tee Splices.

i.Remove the sheath of the through cable a distance of 8 -inches centered on the point of

splice. ii. Remove the sheath of the branch cable a distance of 4 -inches. iii. Separate out and cut the through cable conductors planned for joining to the conductors of the branch cable. iv. Do not cut any other conductors for any purpose.

v.Depending upon the need, the Department will allow placement of the branch cable beside

1 of the through cables. The Department will allow splicing of the through cable or doubling back of the through cable so that the parts of the through cable and the branch cable are placed side by side. vi. Prepare the splice for taping after joining conductors. vii. Place the cables in the approximate final position and inspect the cables for shorts. viii. After positioning all wire nuts and wires, begin taping on the through cable 2 -inches from the end of the sheath. ix. Wrap the tape around the splice proceeding with a 1/2 -inch width overlap across the splice area and onto the other through sheath for a distance of 2 -inches.

x.Wrap the tape from the endpoint back across the splice to the branch cable and onto the

sheath for a distance of 1 -inch. xi. Wrap the tape back from the end point on the branch cable back to the main cable. xii. Tape the remaining part of the splice in the same manner. xiii. Provide rubber tape at least 4 layers, 2 fully overlapped passes deep for every area of the splice. xiv. Place the cables in the final position and tape with 2 fully overlapped passes of plastic tape in the same fashion. xv. Do not use the plastic tape to cover the interior areas covered by the rubber tape. xvi. Place the splice so that the branch cable enters the splice from below to prevent water from flowing along the branch cable into the splice area.

o.Cable Termination End.

i.Remove 3 -inches of sheath from dead -ended cables.

Ii. Wrap each individual cable with rubber tape. iii. Bundle and re -tape with vinyl tape. iv. Coat with waterproofing compound.
