Types Of High Voltage Insulators

This type of insulator is used in the high voltage overhead distribution line. Pin insulators are the earliest developed overhead insulator but are still commonly used in power networks up to 33 kv system. For high voltages 33 kv it is a usual practice to use suspension type insulators shown in fig.

Mostly suspension insulator is made of glass or porcelain insulating.

Types of high voltage insulators.

Hence depending upon the working voltage desired number of discs can be connected in series to form an insulator string suitable for particular voltage. In order to relieve the line of excessive tension strain insulators are used. The discs of strain insulators are used in the. The cost of pin type insulator increases rapidly as the working voltage is increased.

For low voltage lines 11 kv shackle insulators are used as strain insulators. Therefore in this types of insulators in transmission lines insulator is not economical beyond 33 kv. Advantages of suspension insulators. Each unit of disc is designed for a low voltage say 11 kv.

However for high voltage transmission lines strain insulator consists of an assembly of suspension insulators as shown in figure. The suspension insulator is called as disc insulator. In a 11 kv system we generally use one part type insulator where whole pin insulator is one piece of properly shaped porcelain or glass. The pin insulator has a simple construction.

It requires less maintenance as compared to other insulator types. Dirt pollution salt and particularly water on the surface of a high voltage insulator can create a conductive path across it causing leakage currents and flashovers. Most high voltage insulators are designed with a lower flashover voltage than puncture voltage so they flash over before they puncture to avoid damage. Pin type insulator can be one part two parts or three parts type depending upon application voltage.
