Suspension insulators are made up of many porcelain components connected in series by metal rods or links. They have two advantages: They are strong and can handle high voltages. The total flashover voltage rises when several units are connected in series. As a result, the insulator can withstand voltages between several hundred kV and 33 kV.

Ceramic insulators:

Glass and porcelain are two common ceramic materials used to make ceramic insulators. They are famous for their resistance to the environment. They are also known for their durability and electrical resistance. They use ceramic insulators. They are for power distribution, transmission networks, and other high-voltage applications.

Shackle insulators:

These insulators, which are small in size, are used in the overhead electricity distribution system. A metal strip can be used to connect this insulator. This insulator can be utilized in a bending or bending plus-turning arrangement, and it can withstand up to 33 kV voltages. These insulators are exclusively used in low-voltage transmission lines as strain insulators. It is possible to arrange the shackle insulators vertically or horizontally. These are supported by cross arms and bolted to the pole.

Stay insulators:

These tiny insulators are part of the overhead electrical distribution system. They can be connected using a metal strip. They can tolerate voltages of up to 33 kV and are useful in bending or bending plus turning arrangements. As of right now, strain insulators made of these materials are only utilized in low-voltage transmission lines. The shackle insulators can be positioned either horizontally or vertically.
