The porcelain suspension type of insulators are used in medium-high voltage to UHV applications on towers on which the conductor is just suspended. These insulators have ball at the bottom and a socket at the top. so they can fit into one another and form a string as per the voltage requirement.
At the bottom of the string there is a sort of clamp to hold the conductor. To prevent damage due to vibration, armour rods are fixed on the conductor at the point of suspension. The top end of the string is fixed to the cross arm of the tower.
Application Standard: IEC, ANSI, BS, AS, DIN, CAN, GB and etc.
Color: light gray, brown, white, sky blue and etc.
Non-standard products: Designed by CTC or specified by the customers.
