An insulator used to insulate a wire, such as a pin on a utility pole from a physical reinforcement is known as a pin insulator. The pin insulator is used in power delivery for voltage up to 33kV. It is positioned on the cross arm of the supporting tower. The pin insulator has grooves at the top to keep the conductor. The conductor is connected to the insulator by the angled binding wire of the same material as the conductor on the top groove on the straight-line positions and side groove. A lead thimble is cemented into the insulator body to receive the pin.
