Know About Electrical Insulators and Its Application

Shaft Insulators

Electrical insulators are available in different types and sizes. The insulators inhibit the flow of electric current. It functions in the opposite role as a conductor, preventing the electrical particles from flowing freely. They possess high resistivity and low conductivity, making the current flow more efficient. It is advisable to buy from the shaft insulators manufacturers in India for a guaranteed outcome.

 

What is an Insulator?

 

Electric insulators are materials where electrons cannot move freely for atoms and tightly restricted electrons.  Since the electrons have internal electric charges tightly bound together, it restricts current flow.

Thus, the insulators allow a limited current flow in an electrical field. It stands in opposition to the conductors and semiconductors.  You can recognise a typical insulator by its resistivity. When compared to conductors, they possess high resistivity. A perfect example of this case is the non-metals.

When you use insulators in electric equipment, it supports and segregates the conductors to control current flow. Appliances like wrapping cables use electric insulators.

 

Applications of Electric Insulators 

The use of electric insulators is spread across a wide range of applications. In electrical appliances, they prevent high voltage current from causing damage. Sometimes, the technicians apply flexible insulator coating to the cables and electric wires. It is called the insulated wire. In the case of a coaxial cable, the conductor in the middle should be given the proper support at the centre of the hollow to stop the EM wave reflections. If the wires are exposed to a current more than 60V, it can generate shocks. This leads to severe electrocution hazards. Hence the answer to this problem is insulation coatings.

 

Types of Electric Insulators 

 

  • Disc Insulator
  • Pin Insulator
  • Shackle Insulator
  • Post-Insulator
  • Suspension Insulator

An Overview of Transformer Bushings and Its Mechanism  

insulators

The transformer bushing is equipment utilised to test whether the transformers are operating efficiently and correctly. While the most common type of testing is oil testing, you can implement the electrical testing method to get precise results. You can purchase premium quality transformer bushings from the reputable Transformer Bushings Manufacturer in India for product assurance.

 

What is a Transformer Bushing? 

 

The transformer Bushing is a kind of insulating structure that forms the passage for current-carrying, energised conductors through the grounded tank of the transformer. Either the conductor is built into the bushing, like a bottom centred one, or drawing in a separate conductor through the centre. This can be a draw lead or draw rod bushing.  

 

Types of Transformer Bushings 

 

Transformer Bushings usually have two principles, a solid/bulk type and capacitance graded bushing. The latter is also known as the condenser type.  

The manufacturers make solid bulk bushings using porcelain or epoxy insulators. You can mainly utilise this for low voltage windings of the transformer. On the other hand, capacitance graded bushings are designed for high voltage ratings and high voltage windings.  

 

The failure of transformer bushings is considered a leading cause of transformer failure. Hence, the transformer asset owners must consider its quality. There is typical bushing failure because of moisture ingress, lightning strikes, misapplications, corrosive sulphur, broken connections, etc. 

 

Why Should You Test the Transformer? 

 

Routine electrical testing is mandatory, and you should perform it every 3-5 years for the utility companies. For electrical testing, you need to de-energise the unit and isolate it to perform complicated processes. There are several reasons why performing electrical testing of the transformer is essential.  

 

  1. Acceptance Testing.
  2. Bringing the Transformer Out of Storage  
  3. After the Transformer Trips Offline 
  4. Verification of the Oil Test that is unacceptable 

 

Transformer Bushings Maintenance 

 

  • Cleaning  

 

Before testing, you should clean them of the dust, impurities and dirt particles. You can administer a simple bushing cleaning method – elbow grease and soft rags. If the bushings are dirty, cleaning with solvents is also helpful. Other methods are pressure water washing with CO2 and more. 

 

  • Visual Inspection  

 

Check the bushings for cracks and other damages. If the damage is severe, the current leakage can become excessive, showing carbon trackings on the surface. Flashovers can also occur if you do not clean these bushings periodically. 

 

  

  • Thermographic inspection    

 

You can also inspect high voltage bushings with infrared cameras to check loose connections.

Know About the Different Types of Insulators and Their Application 

Conical Support Insulators Manufacturer in India

An insulator is an electronic device that gives support to the poles and overhead line conductors. Its main purpose is to prevent the current flow toward the Earth. In transmission lines, it has an integral role to play. The manufacturers design the insulator using rubber, mica, wood or even plastic. They use special materials like glass, PVC, ceramic, polymer, steatite etc. However, the common material used is porcelain. You can buy them from the reputable Conical Support Insulators Manufacturer in India.

 

Depending on the voltage consideration, there are different varieties of insulators available. In this article, we can take a look at some of these types.  

 

Different Types of Insulator 

 

  1. Pin insulator 

It is a type of overhead insulator; however, it is utilised commonly in power networks that go up to 33kv. You can see one pin, two or three-pin type insulators depending on the voltage of the application. The leakage happens through the surface. Hence it is recommended to increase the vertical length of the insulator surface area. Pin type insulators are secured with lead bolts or steel and put in straight running transmission lines. Beyond 33kv, the insulators are uneconomical.  

 

  1. Suspension Insulator 

This type of insulator contains porcelain discs that are connected via metal links to form strings. It is embedded in high voltage towers. The experts will suspend the conductor at the bottom end of the string while securing the other end to the tower cross arm. Each unit of this disc is designed for low voltage use, like 11 kV. The number of discs is connected appropriately for proper operations. The suspension insulators are suitable for steel towers. It also offers partial protection against lighting. 

 

  1. Strain insulators  

The manufacturers design the strain insulator to handle various mechanical stresses at different angles whenever there is a directional change in the lines. High voltage lines with a longer span and greater loading allow the operatives to arrange the insulator strings into a horizontal position. In those instances where a single string is not sufficient for high load-bearing capacity, they deploy two or more strings in parallel. This enables high conductor tension.      

 

Meet the Experts 

 

The conical insulators are made from porcelain or ceramic. The manufacturers design them accurately to yield maximised performance. They are utilised mainly for electrostatic precipitation, and you can get them in a customised finish.
