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.
