Ⅰ. Usage and characteristic
The damper is used to lessen fatigue damage of breeze to wire.
So there must be reasonable weight and installation location. When dampers slip, this can harm wire more seriously.This kind of anit-slip hippocampus damper that produced by our company has special weight and reasonable
shape design.
It can produce several resonance frequencies and it can also absorb vibration of variable frequencies effectively.
The patent installation with pre-twisted armor rods can ensure large bond area and evenly-
distributed adhesive force so that there’s no stress concentration and the constant installation torque can be stayed.
Therefore, the product can not slip. This can avoid fatigue damage of wire effectively and lengthen service life of lin.
Ⅱ. Installation method:
Especially note: this product is installed by pretwisted wire; make sure that the wire type is coincident with matched installation pre-twisted wire before installation.
1. Hang the damper clamp on the designed installation distance location.
2. Take out one pre-twisted wire out of the three ones and align the central signs to the groove on damper clamp,
then wrap the pre-twisted wire around wire.
3. Repeat step two and finish the rest two pretwisted wires wrapped around wire and make sure the central signs align.
