Electrical Insulators and it's types
The electrical insulator is a device that provides the required insulation between the line conductor and earth. Due to this insulation, leakage current can’t flow from the line conductor to earth. Insulator a material or a device which restrics the flow of free electrons (or charge). The successful operation of an overhead line depends to a considerable extent upon the proper selection of insulation. Importance of Electrical Insulators- The insulator work as a Protector or Protective device. Because it provides high resistance. Insulator helps to protect from heat, noise, and electricity. The insulator is used to support the overhead conductor. It is commonly used to insulate the live parts of equipment or conductor from the earth. The live conductor is protected by wrapping the insulation. It helps to protect switchgear, transformers. Properties of Electrical Insulator- The electrical insulator has a high resistivity. Insulator has good mechanical strength for the c...
