Intense Comparison between Electrical Bushing and Insulator

Do you ever wonder why you should use electrical bushing when the insulator is already there? It might be tricky to think. However, with proper analysis, you can easily differentiate between electrical bushing and insulators. Both bushing and electrical insulators are necessary for transformers, but they work differently for the ultimate benefits of a transformer. If you are searching for one of the most experienced and reliable transformer bushing manufacturers, try to understand the basic similarities and differences between electrical busing and insulators. Let’s discuss this in detail throughout this blog.

Working Aspects of Electrical Insulator

An electrical insulator is one of the most valuable materials that does not conduct electricity. It does not allow the free flow of electrical current. Rubber, glass, and plastic are common materials for electrical insulators. These materials do not conduct electricity and create a barrier between the external environment and live electrical parts.

Due to these unique working aspects, insulators reduce the risk of electric shock and save human lives. Insulators also protect the electrical equipment of a transformer from harsh weather environments such as heat, moisture, and UV radiation.

The Working Structure of the Electrical Bushing

An electrical bushing is a vital insulation component that protects electrical equipment and environmental factors by creating a barrier between live electrical parts and the external environment. Porcelain and fiberglass are the basic materials for electrical bushing. The design of the electrical bushing is so unique.

It consists of a hole through the enclosure to provide a pathway for an electrical conductor to enter or exit. Bushing has a metallic part that conducts the electric current to the device. The bushing can protect the electrical equipment from dust, moisture, and other environmental factors.

Similarities between Electrical Bushing and Insulator

Electrical insulators and bushing both work as crucial electrical equipment in transformers, and we are now describing the similarities between the electrical insulator and bushing.

1. Both consist of insulating material– Electrical insulators and bushing are made from the same insulating materials, such as glass, synthetic polymers, and porcelain.
2. Provide protection and insulation– Electrical bushing and insulators provide insulation and protect electrical components from the external environment.
3. Both have specific designs– Both electrical bushing and insulators have specific designs that are useful to prevent high-voltage electricity.
4. Metallic components– Electrical bushing and insulators have metallic components that conduct the current flow from inside equipment to outside to provide mechanical support.

Difference between Electrical Bushing and Insulator

Both electrical insulators and bushing are useful electrical equipment to provide intense safety to a transformer or other electrical devices, but both of them have a few dissimilarities; let’s discuss them in detail-

1. Components– An electrical insulator consists of an insulating material and a supporting structure, whereas an electrical bushing consists of a conductor section and an insulating section. The conductor segment conducts the current from the outside to the inside of the transformer.
2. Purpose– Insulators mainly support conductors and other electrical components while keeping a safe distance between ground and other electrical equipment. On the other hand, electrical bushings provide a pathway for conductors.
3. Size– The electrical insulator is bigger than the electrical bushing.
4. Function– An insulator provides insulation support to the transformer. On the other hand, electrical bushings provide a pathway for the conductor to enter or exit the electrical enclosure while maintaining the isolation of the electric current.
