Method of selecting insulator type according to wire

1. Insulators can divide into a breakable type and a non-breakable type.
2. According to the structure, it can be classified into column (pillar) insulator, suspension insulator, pin insulator, butterfly insulator, tension insulator, anti-fouling insulator and bushing insulator.
3. According to the application, it is divided into line insulators and power stations and electrical insulators. Among them, the puncturable insulator used for the circuit has a pin type, a butterfly shape, a disc type suspension type, and the non-breakable type has a cross arm and a rod type suspension type.
