China hardwire fastener good price metal protective hardwiressimon2020-06-17T03:21:34+00:00 Project Description Preformed Protection Rod: It is used to wrap around the conductors so as to improve the rigidity and reduce the vibration of conductors. It can also be used to wrap aluminum conductors onto post insulator so as to increase their rigidity and decrease the vibration. Preformed Repair Rod: It is used to prevent conductors and ground wires from the damage of external force, avoid the expanding of damage area, and help the conductors/grounding wires regain its original physical strength and electric conductivity.
