Ceramic Pole Top Pin Insulator Schematic

Similar to their glass counterparts porcelain insulators date back to before the civil war for telegraph wires.

Ceramic pole top pin insulator schematic.

They are secured on the cross arms of the pole to carry power lines. They are mounted directly on the pole or crossarm and bolted in place. There is a. Vise top insulators are molded from a proprietary blend of gray track resistant high density polyethylene.

Their performance was superior to pin type insulators and by the 1960 s they found widespread use on power lines everywhere. Mechanical strength of insulators insulators shall withstand all applicable loads specified in rules 250 251 and 252 except those of rule 250c and rule 250d without exceeding the following percentages of their strength rating for the respective insulator type shown in table 277 1. Pole top insulator pin is 20 length and includes 1 3 8 semi conductive nylon insulator thread. Hendrix vise top insulators are pin type insulators that incorporate a clamping mechanism into the top of the insulator to provide quick and easy conductor installation without the need for additional tie products.
