Disc Suspension Ground Wire Porcelain Insulators are a special suspension insulators which is used to connect the pole tower and the overhead lightning conductor for transmission lines. The ground wire insulator s are featured with small cap diameter and creep distance of insulators. It is equipped with electrode with air gap. Ground wire insulators can be divided into suspension type and tension type according to their installation form and electrode structure.

Main dimensions and properties 

Model description: UE means the cap suspension ground wire insulator, the number 70 or  120   behind refers to the electromechanical failure load (kN) of the insulator

C refers to the suspension type, and CN refers to the tension type.
