A Short Discussion On The Most Common Types Of Insulators

Solid Core Insulators Manufacturer

Insulators are crucial in the entire power transmission and distribution (T & D) industry. For this reason, investments in this industry are also growing globally. These insulators can offer electrical or mechanical support besides preventing a flashover in case of over-voltage. As per different voltage considerations, certain insulators are used in power networks. Electrical insulators are made up of either ceramic, porcelain, glass, or composite polymers. So, let's look at the most common types of insulators in terms of their shape and uses. Contact solid core insulators supplier to buy optimal-grade insulators.

Pin Type Insulators

The first category of insulators in terms of shape and use is pin-type insulators. These insulators include steel or lead bolts onto transmission poles. For this reason, they are used in straight-running transmission lines. However, they are functional only up to the voltage of 33KV.

Beyond the further voltage, these insulators can become uneconomical and bulky. Also known as shackle or spool insulators, these insulators are ideal for low-voltage distribution networks. They can be used both horizontally and vertically. They are placed at the sharp corners of the transmission lines.

Suspension Insulators

The next category is suspension insulators. These insulators include numerous porcelain discs attached to each other with metal links, making them look like a string. The conductor line has a suspension at the bottom end of the string of these insulators.

The conductor line is positioned securely in the tower's cross arm. Strain insulators often help prevent tension in transmission lines. For this reason, they are often placed at the sharp corners or dead ends of the transmission lines. Buy high-end insulators from well-known porcelain insulators manufacturers in India.

Stay Insulators

The next type of insulator is a stay insulator or egg insulator. These insulators are used to prevent stay wires from getting energized and from breaking. Hence, they offer insulation between transmission poles and stay clamps. These insulators require high mechanical strength because they are subject to applications that need sudden pressure, such as surge arresters or circuit breakers.
