The U70C glass insulator adopts a suspension design, and its main applications are also as follows:
Insulating and suspending conductors:Â It is used in high-voltage overhead transmission lines to provide insulation to ground and withstand the mechanical tensile load of the conductors.
Forming insulator strings:Â Depending on the voltage level of the line, multiple insulators are connected in series to form an insulator string for use.
