Armour Rod ADSS Preformed

The preformed armor rod is used to protect against vibration, clamping stress, friction, electric arc and other external damage. The protection armor rods can protect the wire from arc, friction and other damage on the short-span line when the wire vibration is not serious. They can also be used as repair strips to repair damaged wires and restore their original mechanical strength and conductivity. It can also be used to protect the branch lines and avoid damages caused by arcs and friction at the branch points of the wires.

Product Details

The protective wire can avoid damage caused by the aluminum clamp of the anti-vibration hammer directly clamped on the 0PGW optical cable, and has a good protective effect on the optical cable. The factors that cause vibration include span, tension, wind speed, wind direction, ground wire and cable structure size, etc.

Features:

a. Using a unique design, its basic principle is to dynamically absorb energy, its frequency coverage is 6Hz-150Hz, and there are four resonance frequencies in this range, which can meet the needs of various types of OPGW, and has a very effective vibration reduction effect .

b. The hammer head is permanently bonded to the suspension wire and can withstand the mechanical load under installation, maintenance, and operation conditions.

c. Unique shape design, no accumulation of water, no icing.

d. The installation is convenient and safe, and does not cause damage to the wires and ground wires.

e. The anti-vibration hammer adopts anti-corona design to prevent the occurrence of corona.

Selection of anti-vibration hammer

1. Choose a hammer

2. Select the diameter of the installation wire. Considering the main technical parameters of OPGW cable, such as tension, wind speed, terrain and other factors, determine the selection of anti-vibration hammer.

Selection of wire diameter: The diameter of the wire is the sum of the diameter of the optical cable and twice the diameter of the twisted wire in the tension clamp (or suspension clamp). When installed on the protective wire, the diameter of the wire is twice the diameter of the optical cable plus the diameter of the protective wire.

Precautions:

1. According to calculation, if the installation position of the anti-vibration hammer falls on the inner stranded wire, it is not necessary to install the protective wire, and it can be installed directly.

2. If the calculated installation position of the anti-vibration hammer falls on the optical cable, a protective wire must be installed, and the end of the protective wire must be at least 50mm away from the end of the inner strand.

3. If the installation position of the anti-vibration hammer falls on the outer stranded wire, it can be offset a little and directly installed on the inner stranded wire, but the center of the anti-vibration hammer is greater than 50mm from the end of the outer stranded wire.

4. Hammer head orientation: The small hammer head faces the tower.
