Trough Type Electric Pole Glass Insulators Glass Suspension Disc Insulators
Electric Pole Glass Insulators Overview
A Suspension Insulator, which is also known as a Strain Insulator, is a type of insulator designed to protect the overhead power line. The insulating materials for this insulator comprise discs connected to each other by string-like metal links. The transmission line conductor is suspended at the bottom side of the suspension string, which connects directly to the pole or tower.
Here are different insulation materials that are used on the suspension insulators. They include porcelain, glass, polymer, ceramic, and crystals such as quartz.
The main difference between pin insulator and suspension type insulator is their insulation capacity. Suspension insulator is ideal for transmission lines with more than 33Kv. The transmission line voltage will dictate the number of discs to be used on the suspension insulator.
The ability to overcome the pin insulator’s limitation capacity is the main reason why suspension insulators are preferred for most transmission lines. Of course, you have to keep in mind all other technical and non-technical factors before deciding whether to use a pin insulator or suspension insulator.
