post type insulator
|
to insulate and separate conductors form grounds and other lines. Porcelain insulators are mounted withe steel studs. Smaller insulators take a 5/8 threaded stud; larger insulators require a 3/4 stud. Post type insulators are installed on both primary distribution and high voltage transmission circuits. Conductors are either pre form tied, hand tied or clamped to the insulator.
|
|
|
Pin type insulator
|
The purpose of pin insulators is to insulate and separate conductors from grounds and other lines. porcelain insulators are mounted withe steel pins. Smaller insulators take a 1" threaded pin; larger ones require a 1-3/8 pin. Pin type insulators are mostly installed on primary distribution and secondary distribution circuits.
|
|
|
Suspension/dead end insulators
|
insulators that are attached to crossarms and towers with a conductor attached to the opposite end. They are used to dead end conductors or to support and angle when there is a change in the direction of conductors in a line.
|
|
|
Spool and clevis type insulators
|
Circular insulators used in combination with metal brackets, which in turn are installed on crossarms, poles and other conductor support brackets. They are used to dead-end or support secondary and service conductors.
|
|
|
What must be done with the tool before cutting a conductor
|
read manufactures's recommended usage
|
|
|
What length bolt is required for a crossarm when installing it?
|
Cross arm bolt is hole depth +6"
Brace bolt is hole depth +2" |
|
|
What is the measurement below the crossarm hole for drilling hole for braces. (8 ft crossarm with 36" braces)
|
19 1/4"
|
|
|
down guy
|
a guy wire attached at or near the pole top that runs to a buried anchor and rod at ground level. its purpose is to support the pole and equalize the strain created when line conductors are dead ended on poles, or when the direction of the conductors causes an angle strain to be applied to the pole
|
|
|
Head Guy
|
head guy a guy wire attached to the top and running to a point below the top of the adjacent pole. Used to offset down hill strain of line conductors and balance uneven strains created by double dead ending line conductors of different weights back to back at the same position on the pole
|
|
|
Span Guy
|
A guy wire installed from the top of one pole to the top of an adjacent pole. Its purpose is to transfer strain created by conductors from the first pole to the second pole.
