A Disc Suspension Insulator is generally made of disc shape insulator part(such as porcelain part,glass part) and metal accessories.
Disc Suspension Insulator is widely used in transmission overhead line,consiting of 1 insulator and a string of insulator, shoulder the important task of hanging wire and insulting the tower.
1.Normal Disc shaped insulator with ball and socket connection or slot conntection.
2.Fog Type disc insulator has a long underside of the umbrella to keep the inner part from moist.
3.Anti pollution type disc insulator with double shed. which has large creepage distance that can be used in high pollution area.
