Classification of Helical Materials

Armor Rods

Armor rods are designed to be wrapped around the outer layer of overhead power line strands. The Armor rods are mounted on boat-shaped wire clips and pillar insulators to protect the strands from various electrical and mechanical damage.

Spiral Vibration Dampers

SVD Series Spiral Vibration Dampers are designed to eliminate the damage caused by Aeolian vibration and reduce overall vibration on bare cables. Made of weather-resistant, non-corrosive plastic, these dampers have a large, helically-formed damping section sized for the cable.

Insulator Side Tie

Side tie are intended to secure bare or jacketed distribution conductors in the side groove of vertically and horizontally mounted insulators. They provide superior abrasion protection for the conductor under all typesl of motion, including Aeolian vibration, galloping and sway.

Insulator Top Tie

Top Ties are intended to secure bare or jacketed distribution conductors in the top groove of vertically mounted insulators. They provide superior abrasion protection for the conductor under all typesof motion, including Aeolian vibration, galloping and sway.

Usage of Spiral Vibration Dampers(Helical Materials)

Each damper is marked with the conductor range and color coded to indicate the cable diameter size range. Line design, temperature, tension, wind flow exposure and history of vibration on similar construction in the location are factors to consider when determining the amount of protection required. Installation can be on both sides of the support location—at least one hand-width from the ends of Armor Rods or cable hardware.

FAQ

Q: What is the function of helical materials?

A: Insulator top tie is used to secure the line conductor to the top groove of the pin insulator, ensuring the conductor remains in position on the insulator even under environmental stresses. It also has a protective layer to prevent damage to the conductor and insulator, and proper tension from it reduces sag and maintains the desired clearance from the ground.

Q: What materials are helical materials usually made of?

A: Common materials include aluminum - clad steel, galvanized steel, aluminum alloys, etc. These materials provide high tensile strength, can withstand mechanical stresses, and have corrosion resistance.

Q: How does helical materials protect the conductor?

A: The top tie has a cushioning layer that protects the conductor from damage due to direct contact with the tie wire. It also helps in dampening vibrations and absorbing impact. Additionally, some top ties have armor rods that provide extra mechanical support and protection for the conductor, distributing mechanical loads to protect it from wear and abrasion.

Q: Helical materials: What is the difference between a side tie and a top tie?

A: A top tie secures the conductor to the top groove of the insulator, while a side tie mounts the conductor to the side groove of the insulator. The side tie uses pin - or post - type insulators that install on the cross arms, and it contributes to mechanical stability in certain setups. Top ties are mainly used to keep the conductor in the top position of the insulator and are more related to preventing sag and maintaining ground clearance.

Q: Why do the side tie rods in helical materials adopt a spiral design?

A: The helical or spiral shape of the side tie wire helps distribute the holding force across the conductor and reduces point loads. It also allows the side tie to have a certain degree of flexibility to accommodate small movements of the conductor and handle dynamic loads, helping to prevent mechanical stress on the conductor and insulator.
