Ceramic Discs On Power Lines

An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy across large distances.

Ceramic discs on power lines.

The wagner quickstop ceramic disc pad set represents a fantastic value oriented option that offers decent stopping power durability and low brake dust buildup. Hence overhead power lines are always supported on insulators mounted on their support poles towers. Different types of insulators in transmission lines. Craft supplies coin beads handmade ceramic disc beads made to order you pick the color palette marsha neal studio porcelain clay marshanealstudio.

5 out of 5 stars 3 610 3 610 reviews 3 00. Favorite add to. From what i ve noticed high voltage ceramic insulators only insulate conductors end to end not inside to outside like traditional plastic insulators. The dummy pole has no conductors attached to it and is placed generally within 100 ft 30 m of the power line.

The platform is made taller than the line to make it the preferred perch. To make defective units obvious glass units are designed so that an overvoltage causes a puncture arc through the glass instead of a. This is an in service illustration of an osprey utilizing an alternate nesting platform provided by one utility. It consists of one or more uninsulated electrical cables commonly multiples of three for three phase power suspended by towers or poles.

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. Of course the power line won t even work in that case. Line voltage kv discs.

I ve seen these stacked disc structures on high voltage power lines everywhere. Power lines supported by ceramic pin type insulators in california usa. I could not find any information regarding this particular shape though. 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 successful operation of an overhead groo line depends to a considerable extent upon cond the proper selection of insulators. But the number of insulating ceramic discs suggests that a little more than 161 kv is flowing through the power lines.
