Grounding Roller Stringing Blocks (Grounding Roller Stringing Blocks) are specialized safety equipment used in overhead transmission line stringing construction. By integrating a grounding device with a guide pulley, they guide conductors and optical cables while safely directing the induced current generated by the conductors to the ground during construction. Their core value lies in eliminating the risk of electric shock to construction workers caused by induced current and preventing potential damage to equipment. They are a key component for ensuring safety and construction quality during high-voltage line installation.
