Preformed Helical Suspension Clamp is a common hardware for hanging optical cables on transmission line towers, and it plays an important role all the time. Preformed Helical Suspension Clamp is mainly used for connecting optical cables with straight towers or towers with an angle of less than 25°, one set for each tower. The wire clamp can reduce the static stress of the optical cable at the suspension point, improve the vibration resistance of the optical cable, and overcome the dynamic stress of wind vibration; it can also ensure that the bending of the optical cable does not exceed the allowed value, so as not to generate bending stress, thus ensuring that the optical fiber will not be lost.
However, some workers often ignore the importance of installing Preformed Helical Suspension Clamp. In fact, accidents caused by mistakes often occur, such as: Preformed Helical Suspension Clamp depends on the close fit between the Preformed wire and the surface of the conductor. If the twisted wire spacing error exceeds ±1mm or the torsion angle is improper, it will lead to uneven stress distribution and accelerate the fatigue fracture of the cable. If the Preformed wire installation tool (such as the tension controller) is not calibrated or the operation is not standardized, it will also lead to insufficient preload or overload. Leading to wire breakage, so what should we pay attention to during the installation process? What can we do to reduce accidents caused by human beings?
First of all, the material should be checked before installation to ensure that the specifications of the wire clamp are completely matched with the outer diameter and structure of the wire. Check whether the wire clamp is deformed, cracked, rusted, and whether the Preformed wire is intact. Secondly, it is forbidden to install in strong winds, rain, snow, and haze weather, which will affect the operation and cause danger to workers. The spiral direction must be consistent with the twist direction of the wire (usually right-handed), and reverse installation will cause slippage. It is forbidden to mix wire clamps from different manufacturers and use deformed or rusty wire clamps with accessories.
