Lineman definitions EXAM QUESTIONS WITH VERIFIED ANSWERS A+ PASS Easy-out lag bolt - Answer- The spiral grooves on this bolt make it eastier to screw out of a pole. It has the same strenght as other lag bolts Carriage Bolt - Answer- This bolt is used to attach cross arms to the pole and braces to the cross-arm Double-arm (DA) bolt - Answer- This bolt is a fully threaded (all thread) rod. Two square nuts and a washer are installed at each end. Such bolts are used to attach the cross-arm to the pole flat washer - Answer- This is used for multiple mounting applications on the pole. Two washers are normally used per bolt unless a Clovis is attached on one end. Insulator Pin - Answer- Used to attach a conductor insulator. The pin positions the insulator and conductor away form the pole. Hot clamp - Answer- This is used for connecting a wire to a primary conductor and is available in various sizes. The hold in the end is to accept an insulated hot stick Copper KVS clamp - Answer- This is a grounding clamp used to king a ground wire to a grounding rod or to join two ground wires together Eye Nut - Answer- Available in 3/4 and 5/8, this is used as an attaching point for various items and lines such as guys set low on the pole wedge shoe - Answer- This is an aluminum shoe used to secure aluminum wire. Commonly used as a dead-end clamp, the tension of the conductor secures the wedge onto the conductor. Bolted shoe - Answer- This is a bolted shoe used to secure aluminum wire. Similar to the wedge shoe, this shoe must be bolted onto the conductor to secure it. Ground wire clamp - Answer- This is used to secure a ground wire to the pole grounding rode Fused cutout - Answer- The gated cutout serves as a circuit overload protector for secondary conductors and components Guy hook - Answer- This serves as an attaching pint for an insulated guy rod and guy wire make up Cross-arm bracket - Answer- This serves as a cross-arm mount on a pole. Cross arm braces are not necessary with the use of this bracket Orange (color code) - Answer- #4 Red (color code) - Answer- #2 Yellow (color code) - Answer- #1 /ALt Gray (color code) - Answer- #2/Alt Pink (color code) - Answer- # 4/Alt Black (color code) - Answer- #3/Alt Splices - Answer- Are used at times to repair damaged conductors, most common is compression splices and helical rod type or automatic splices. Connect two wires together acting as one Single cross-arm - Answer- Used to support two or more primary conductors, also be used for dead ending conductors, cutouts and lighting arrestors may also be attached to the cross arm Double cross arm - Answer- Used when increasing support is required for the tension or weight of conductors and components, they are typically joined tougher at the ends with threaded rods and nuts to stabilize the ends of the cross arm Triple cross arm - Answer- Used for dead ending a long run of large primary conductors, with this arrangement two single arms are joined together on the back of the pole and a single cross arm is mounted on the front of the pole, they are all joined together at the ends with threaded rods and nuts, these triple cross arms are used in place of extra strength 5;1/2 X 5;1/2 cross arms What does a capacitor do? - Answer- stores energy What does a load regulator do - Answer- Maintains a constant output voltage from a power supply, regardless of changes in the connected load current deadend - Answer- a point on a power line where the conductor (wire) is terminated and held under tension so it cannot continue any farther. Instead of passing through a pole to another span, the wire is anchored securely to the pole or structure using a dead-end insulator and hardware.
