Ceramic Discs On Power Lines

The successful operation of an overhead groo line depends to a considerable extent upon cond the proper selection of insulators.

Ceramic discs on power lines.

There are several types of insulators in transmission lines but the most commonly used are pin type suspension type strain insulator and shackle insulator. In utah there are power lines with 12 ceramic discs on the power poles holding or suspending the power lines. It consists of one or more uninsulated electrical cables commonly multiples of three for three phase power suspended by towers or poles. Since most of the insulation is provided by the surrounding air overhead power lines are generally the least.

Each unit is constructed of a ceramic or glass disc with a metal cap and pin cemented to opposite sides. I could not find any information regarding this particular shape though. Favorite add to. The platform is made taller than the line to make it the preferred perch.

The dummy pole has no conductors attached to it and is placed generally within 100 ft 30 m of the power line. Hence overhead power lines are always supported on insulators mounted on their support poles towers. Of course the power line won t even work in that case. 5 out of 5 stars 3 610 3 610 reviews 3 00.

I ve seen these stacked disc structures on high voltage power lines everywhere. Craft supplies coin beads handmade ceramic disc beads made to order you pick the color palette marsha neal studio porcelain clay marshanealstudio. An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy across large distances. Power lines supported by ceramic pin type insulators in california usa.

The power lines only have 138 kv flowing through the power lines. This is an in service illustration of an osprey utilizing an alternate nesting platform provided by one utility. Overhead line insulators it is obvious that if overhead power lines are not properly insulated from their support poles towers the current will flow towards the ground through the poles towers which also become hazardous. The wagner quickstop ceramic disc pad set represents a fantastic value oriented option that offers decent stopping power durability and low brake dust buildup.

Different types of insulators in transmission lines. Line voltage kv discs.
