It requires less maintenance as compared to other insulator types. Primarily applied to networks with a voltage load of 33 kv and above, a conductor is attached to the bottom end of the insulator and suspended from it, separating that conductor from others on the line. Each disc is made up of the same type of insulating material placed between two metal links and has the same permittivity.
Suspension Insulator
[ sə′spen·shən ¦in·sə‚lād·ər] (electricity) a type of insulator used to support a conductor of an overhead transmission line, consisting of one or a string of insulating units suspended from a pole or tower, with the conductor attached to the end.
With the number of metalink links.
Not to mention, one of the biggest advantages of using a suspension insulator is that if one of the porcelain discs gets damaged. These insulators are made with glass otherwise porcelain. Suspension type insulator consists one or more insulator unit connected together to form a string and hanged to the cross arm of supporting structure or tower and carry power conductor at its lowest extremity. They are used in overhead electrical wiring, to support radio antennas and overhead power lines.
An insulator that is used to isolate a wire from physical support such as a pin on a utility pole or tower is known as pin type insulator.
Mostly, suspension insulator is made of glass or porcelain insulating materials. Pin, suspension, and strain insulators are used in medium to high voltage systems. A material that is a poor conductor (as of electricity or heat)… The suspension insulator is called as disc insulator.
Especially, glass types of insulators used in the lightweight condition.
Suspension type insulator consists of one or more insulator units connected together to form a string and hanged to the cross arm of the supporting structure or tower and carry a power conductor at its lowest extremity. Suspension insulators are modular insulators which help to protect a power line from overloading using a conductor suspension method. This type of insulator is used within 33kv power distribution systems. This type of composite unit also called as string type insulator.
There are 5 types of insulators used in transmission lines as overhead insulation:
A suspension type of insulator consists of a number of insulator discs joined by metallic links. A strain insulator is an electrical insulator that is designed to work in mechanical tension, to withstand the pull of a suspended electrical wire or cable. The arrangement of insulators highly depends upon the weather condition, voltage, the size of the insulator, etc. A suspension type insulator is nothing but a number of porcelain discs connected in series by metal links in the form of string.
Type of insulators used in transmission lines.
How to use insulator in a sentence. Suspension insulator pdf can let you know more about suspension insulator. That’s why sometimes we also call suspension insulators disc insulators. The number of units/discs used in a suspension type insulator depends on the operating voltage.
Suspension insulators or suspension strings are developed by attaching a number of closed insulators in series using metallic links.
The meaning of insulator is one that insulates. The arrangement of such types of insulators depends upon the weather conditions, the size of the insulator, and voltage. While stay and shackle insulators are mainly used in low. This article mainly talks about disadvantage of suspension type insulator and advantages of suspension type insulators.
Fog type disc suspension porcelain insulators fig.1 fig.2 fig.3 cat.
As the name suggests, it is arranged on a pin where the conductor connected to it. The suspension insulator consists mainly of two parts one is the cross arm and the other is the insulator which we also know as the disc insulator. Suspension insulators are cheaper in cost compared to pin type insulators each unit of suspension insulators is designed for comparatively low voltage (11kv) and can be increase the insulation strength. A strain insulator may be inserted between two lengths of wire to isolate them electrically from each other while maintaining a.
