Before training a cable into position, the cable end should be thoroughly inspected and it is also important that the cable be ?
free of all contamination and moisture
After reading the written instructions and studying the drawing, the workman should write the ? on the drawing.
dimensions for the specific cable and voltage
The most common cable jackets are rubber or thermoplastic and ?
For cleaning a cable jacket, a cable cleaning solvent is recommended.
Two methods that can be used for penciling the cable insulation include using a sharp knife and non-conductive abrasive cloth, and using a ? .
mechanical penciling tool
Refer to the Terminations & Splices Theory - Practice Textbook "Splicing Instructions, 5 kV through 35 kV, Single Conductor - Shielded Power Cable."Assume the cable is rated for 15 kilovolts ungrounded (133%), and the connector is three inches long. The jacket on each cable must be removed for ? .
Refer to the Terminations & Splices Theory - Practice Textbook "Splicing Instructions, 5 kV through 35 kV, Single Conductor - Shielded Power Cable."Assume the cable is rated for 25 kilovolts, and the connector is four inches long. The insulation for each cable shall be exposed for ? .
Refer to the Terminations & Splices Theory - Practice Textbook "Terminating Instructions, 5 kV through 35 kV."Assume the cable is rated for 15 kilovolts grounded (100%), and the application will be an indoor location. The peak of the stress cone should be built-up to a thickness of ? above the cable insulation
Refer to the Terminations & Splices Theory - Practice Textbook "Splicing Instructions, 5 kV through 35 kV, Concentric Neutral - Shielded Cable ..."Assume the cable is rated for 15 kilovolts grounded (100%), and the connector is 3 1/2 inches long. The cables should be overlapped ? to provide excess length of concentric wires, enough to jumper around the splice.
Refer to the Terminations & Splices Theory - Practice Textbook "Instructions for Cable Tools."The Type JRT Jacket Removal Tool will remove the jacket from any solid dielectric shielded cable.
The type of poor workmanship that is the number one cause of cable accessory failure is ?
cuts made in the cable insulation during removal of semi-conducting layer
The number one problem found when removing the semi-conductor from the insulation of the cable is ? .
ring cuts too deep into the insulation
There are ? layers of cable that will be stepped during cable preparation.
The ? is the outermost layer that is stepped during cable preparation.
The conductor is never stepped during cable preparation.
The two knife blades that are recommended for cable preparation are the hook blade and the ? blade; both provide good control for precision scoring, slitting, and cutting.
A wood folding ruler and a(n) ? caliper are two measuring tools that should be included in a cable splicing toolbox.
When cutting off the end of a large diameter cable (e.g. a 15-kilovolt, 3-conductor, 500 kcmil, interlocked armor cable), a ? would be a good traditional hand tool choice for making the cut square.
A craftsman would include a roll of cotton chalk line with his or her cable preparation tools because it works well for cutting through polyethylene insulations, cuts fast, and will not damage the underlying conductor.
The layer of a cable that a stripping tool, such as the speed stripper, is designed to remove is the ? .
Scoring tools are primarily used for removing the semi-conducting layer of cable.
When preparing a concentric neutral cable, care must be taken to not damage or break off any of the neutral strands, because damage to the individual neutral strands will ? .
DE-RATE AND COMPROMISE THE CIRCUIT
A common field practice to protect the metallic shielding and semi-conducting layer of a three-conductor armored cable from being damaged by the cut-back edge of armor is to leave a(n) ? .
SHORT LENGTH OF THE CABLE'S FILLER MATERIAL EXTENDING BEYOND THE ARMOR CUT-BACK
A ? is sometimes specified for ring-cutting the semi-conducting insulation shield instead of ring-scoring it with a knife or scoring tool.
ROUND FILE (RAT FILE)
Before starting the installation of a splice, termination, or elbow, the prepared cable (semi-conducting shields and insulation) should be washed down with a cable cleaning solvent.
The abrasive cloth used when preparing cable insulation is to be of ? grit.
The abrasive cloth to use when preparing cable insulation must be ? .
The abrasive cloth used when preparing cable insulation must be made of abrasive aluminum oxide.
A cable's strand shielding layer is not stepped like the other layers of the cable. It is removed during the insulation removal step because the strand shield and insulation layers are bonded together and are removed as a single piece.
