To degrease, immerse the broomed end and
approximately 1 inch of the seizing into the solvent in
the ultrasonic degreaser unit tank (see fig. 3-49).
The cleaning solution must be changed after 10
uses.
Replace the rinsing solution when it becomes
cloudy.
After cleaning the broomed end, slowly lift it out of
the solution, allowing it to drain over the tank. Now,
rinse the broomed end in the bucket of clean
GRISOLVE PEG-2 then remove it and allow it to
air-dry for 5 minutes as shown in figure 3-49. After the
broomed end has dried, inspect it to ensure that all dirt,
grease, and all other foreign matter have been removed.
If necessary repeat the cleaning/degreasing operation.
Following degreasing, the cleaner residues must be
rinsed from the wire broom. Heat a 3-gallon bucket of
clean, potable water to a temperature of 160º to 200ºF.
Immerse the broom in the rinse bucket of hot water until
half of the seizing is immersed. Allow the broom to
rinse for 2 or 3 minutes, gently swirling the terminal to
agitate the water. Remove the terminal from the water
and shake off the excess.
Following the rinse, examine the broom for any
preservative remaining on the wires, especially where
wires touch. If preservative accumulations are still
apparent, reimmerse the broom into the degreaser,
repeat this cycle using clean rinse water each time until
the broom appear clean.
After the broomed out wires have been thoroughly
cleaned, wrap the end of the wire rope with two
longitudinal strips of pressure-sensitive tape for a
distance of 2 feet, leaving the broomed out wires and
1/2 inch of the seizing exposed (fig. 3-50).
The method used in preparing wire rope and
terminals for zinc-poured terminals includes a grit blast
method for etching the cables and terminals prior to
pouring.
The following steps are used in the grit blast method:
1.
Fill the cabinet hopper with loose grit, 100
pounds minimum to 200 pounds maximum.
2.
Install the applicable inserts in the cabinet,
depending on the size of the purchase cable
being cleaned.
