2.1.4
Anode Lead Wires
Not less than [No. 8] [No. 6] [_____] AWG stranded copper conductor with [
2.8 mm110 mils [_____] thick ASTM D 1248, high molecular weight
polyethylene (HMWPE) insulation] [an inner jacket of one mm 40 mils [_____]
of ethylene chlorotrifuoroethylene insulation covered by an outer jacket of
1.6 m 65 mils [_____] of ASTM D 1248, high molecular weight polyethylene
(HMWPE)] [a primary insulation of ethylene propylene rubber and an outer
jacket of chloro sulphonated polyethylene], [3050] [6100] [_____] mm [10]
[20] [_____] feet in length [of sufficient length to extend to junction box
without splicing].
2.1.5
Attachment of Anode Lead Wire
Anode lead wires shall be factory installed.
2.1.5.1
End Connected Anode
[Drill] [Cast] a recess [150] [_____] mm [6] [_____] inches deep in one end
of the anode. Attach the lead wire to the anode with an anchor device.
Not more than 10 mm 1/2 inch of bare wire shall protrude from the anchor
device. Attachment shall withstand a 1446 Newton 325 pound pull without
loosening the wire or anchor device. Fill the recess with an [asphalt]
[epoxy] sealing compound [, leaving sufficient space for a plug]. [Provide
non-metallic plug flush with the anode end surface.] [Install a heat
shrinkable anode cap over the attachment, cap shall extend not less than 65
mm 2 1/2 inches on the lead wire and 75 mm 3 inches on the anode.] Cable
to anode contact resistance shall be 0.02 ohms maximum.
2.1.5.2
Center Connected Anode
Attach the lead wire to the center of the anode with an anchor device
suitably fastened to the wire. Not more than 20 mm one inch of bare wire
shall protrude from the anchor device. Encapsulate [each side of] the
connection point with a minimum of 152 mm 6 inches [_____] of high voltage
insulating compound mastic [and 102 mm 4 inches [_____] of epoxy resin].
Attachment shall withstand [4000] [6675] [_____] N [900] [1500] [_____]
pounds pull without loosening the wire or anchor device. Provide a
non-metallic [plug flush with the anode end] [end cap] to prevent chaffing
of the anode lead wire. Cable to anode contact resistance shall be 0.02
ohms maximum.
2.1.5.3
Mixed Metal Oxide Anode Lead Wires
[[Solidly crimp] [and solder] the connection between the anode rod or
ribbon and the lead wire. Seal the connection [with two layers of half
lapped mastic tape covered with a heat shrinkable sleeve] [in cast epoxy].]
[Tin and anneal the copper wire and hydraulically swage the tubular anode
onto copper bushings in contact with the wire. Place a 28 mm 1 1/8 inch
long copper sleeve, inner diameter slightly larger than the tubular anode
outer diameter, over the tube prior to swaging.] Cable to anode contact
resistance shall be 0.02 ohms maximum.
