Transmission Towers – Ultimate Guide to A, B, C, and D Type

by

Power Transmission Utilities use lattice-structured transmission towers for extra high voltage transmission lines and ultra-high voltage transmission lines, normally above 33 kV or including 33 kV lines. They use galvanized iron or GI angles with nuts and bolts to erect the electrical transmission towers. The height of these towers ranges from 20 to 40 meters, … Read more

Disc Insulators in High Voltage Transmission Lines 

by

Before we discuss the use of disc insulators in high-voltage transmission lines, let’s understand the need for such insulators.  Transmission lines operate at very high voltages such as 66 kV, 132 kV, 220kV, 400 kV, even 765 kV and more. So, the conductors used in these systems are also very heavy. To maintain proper ground clearance, we suspend these … Read more
