Dutco Tennant is proud to introduce the ARMOR-GRIP® Suspension (AGS), an advanced and energy-efficient conductor hardware solution designed to optimize the performance and longevity of high-temperature conductors in power transmission systems.

Dutco will be showcasing the Conductor Support System at the Middle East Energy Exhibition (MEE) 2025 in Dubai, where energy professionals will have the opportunity to discover its unique features and specifications.

This innovative suspension system effectively addresses critical challenges such as wind-induced stresses, aeolian vibration, and galloping, ensuring reliable and efficient energy transmission even in the harshest conditions.

What is ARMOR-GRIP® Suspension (AGS)?

The ARMOR-GRIP® Suspension (AGS) is a high-performance suspension system designed to protect and support aluminum conductors at suspension points.

Engineered with cutting-edge materials and technology, it offers unparalleled durability, reducing wear and tear on conductors and minimizing maintenance costs over time.AGS effectively mitigates the stresses that occur due to environmental factors like wind, ice, and temperature variations.

It is also well-suited for high-temperature conductor suspension, ensuring optimal performance even in demanding thermal conditions.

 Additionally, AGS provides excellent vibration damping for power lines, reducing the risk of fatigue damage caused by aeolian vibration. This makes it an ideal solution for applications in regions with extreme conditions, ensuring a smooth and stable transmission of electrical power.

Key Features

  • Durable Rubber Inserts with Strong Aluminum Support:

The suspension system uses special neoprene inserts (a type of flexible rubber) that are reinforced with strong aluminum alloy. These inserts absorb and spread out the pressure and stress that build up on the conductors. This helps protect the conductors, making them last longer and reducing the risk of damage.

  • Minimal Compressive Load Design:

The aluminium strap design ensures that the compressive load on conductors is minimized, allowing for optimal performance under various load conditions. This reduces the risk of conductor fatigue and damage over time.

  • Two Temperature Variants:

The ARMOR-GRIP Suspension comes in two temperature variants to cater to different operational environments:

    • Standard Model: Rated for continuous operation up to 200°C.
    • High-Temperature (HT) Model: Rated for continuous operation up to 250°C, providing enhanced durability for high-temperature applications.

 

  • PARROT-BILL® Rod Ends:

The system includes PARROT-BILL® rod ends, which are specially designed for Extra High Voltage (EHV) systems (345 kV+), ensuring that AGS can be used in large-scale and high-voltage power transmission projects.
 

  • Compatibility with PLP Attachment Hardware:

The ARMOR-GRIP Suspension is fully compatible with PLP’s standard attachment hardware, such as the YP-5910 yoke plate, making it easy to integrate into existing power transmission systems.
