Details of AC, ACSR conductor anti-vibration weights
Wireless dumbbells led include: wired dumbbells led ACSR, AAC, ACKP, ;vibration barbell for rope TK lightning protection, vibration weights for ADSS OPGW fiber optic cable with the feature of two counterweights connected by twisted aluminum cable helps vibration weights have elastic oscillation effect anti-vibration for AC, ACSR conductors.
Operating principle anti-vibration dumbbell is the principle of synthesis of two oscillations (motor oscillation). If the two oscillations are out of phase, they will tend to cancel each other out.
Suppose there is a wind blowing some distance EZ from the equilibrium position:
Since the two ends of the Z range have been fitted with anti-vibration weights, the weight is greater than the weight of the section without weights. so when the rope moves, the unweighted section will move before the weighted section moves after. This will stop the movement of the unweighted segment. After reaching the amplitude line of the oscillation, the unweighted piece of wire has a tendency to return while measuring the two weighted segments has not yet reached the amplitude position (due to the phase delay mentioned above) so there is still a tendency go out. Since these two oscillations are in opposite directions, they will cancel each other!
Anti-vibration dumbbell for GSW lightning wire, TK 50,70, 90 , Pastel rope 147, 288, Phlox rope with the feature of two counterweights connected by twisted aluminum cables to help anti-vibration weights have elastic vibrations and anti-vibration effects for lightning protection lines before the influence of wind hurricane or earthquake.
The lightning rod anti-vibration bar is an accessory used on 110kV, 220kV, 500kV transmission lines and lines in substations. The role of lightning rod anti-vibration dumbbells is indispensable on lines, lightning-resistant anti-vibration weights are installed away from the pole with a certain distance calculated in advance, depending on the conditions of the construction site. installed, the number of anti-vibration weights for lightning protection lines may increase when the line crossing is large and the deflection is high.
Commonly used anti-vibration dumbbells are FG50, FG70, FG90 and FD-1, FD-2, FD-3, FD-4, respectively, with different anti-vibration weights suitable for each type of rope. conductors, lightning conductors, and optical cables are selected based on the cable diameter.
