Duct Rodders applies in tow lead-rope through a pipe, it is auxiliary means. Surface smooth and high resilience, so the FRP perforator with ease passes the narrow channel. perforator consists of two parts: the glass fiber strengthen the level, the high-pressured low density polyethylene protective layer(smooth, firm ,can resist the adverse circumstance). It has time-savingreducing effort, improving efficiency, etc ,And can be used for telecom cables, cable pipe and cleaning and plastic pipe of cloths to put. when use draws out the FPR pole by the pulley, then with a corresponding metal joint, penetrates in the pipeline. When cleaning, guide-head will drive cleaning tools to clean the pipe; When arranges the cable, you may first leads the steel wire or the iron wire, then enters the pipe with the steel wire or the iron wire hauling cable.
