Strain Insulators

Distribution Insulators - 66kV & Below

An electrical overhead distribution strain insulator is a type of insulator used on distribution power lines to manage the mechanical tension (strain) in the conductor where it connects to a pole or structure, especially at dead ends or sharp corners. It provides electrical isolation while also withstanding the pulling force of the conductor. They must effectively prevent electrical current from passing through them, maintaining the integrity of the electrical circuit

Applications:

Dead Ends: Where the power line terminates at a pole or structure.
Sharp Corners: At locations where the line changes direction, especially at angles that create significant tension (greater than 20 deg).
Low Voltage Distribution: In some low-voltage distribution systems, shackle insulators may be used as strain insulator
