As the energy transmission industry evolves, the need for durable and efficient solutions grows. ARMOR-GRIP® Suspension systems are leading the charge, offering exceptional support, vibration reduction, and protection for electrical conductors, including high-temperature conductors.

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.

Here’s a closer look at the Conductor Support System specifications, its installation process, and why it’s a game-changer for energy transmission.

What is ARMOR-GRIP® Suspension?

ARMOR-GRIP® Suspension is a state-of-the-art system designed to support and protect electrical transmission lines, making them more reliable and durable.

Its main function is to reduce the vibration of conductors while offering superior mechanical strength, ensuring that the transmission system performs optimally over long distances.

The ARMOR-GRIP Suspension Double will be prominently featured by Dutco at MEE 2025, highlighting its critical role in the stability of energy networks.

Detailed Overview of ARMOR-GRIP® Suspension: Double

The Conductor Support System: Double is engineered to offer advanced protection for transmission lines. Below are its key specifications and features:

Features

  • Stress Reduction: This system minimizes static and dynamic stresses at the support point, significantly reducing conductor oscillations that can lead to damage. It helps ensure that conductors are not subjected to unnecessary wear and tear.
  • Protection: The product provides robust protection against impulse and power flash-over, bending stress, compression stress, and abrasion. This ensures the system operates efficiently in various conditions, reducing the need for frequent maintenance.
  • Superiority: It is considered superior to traditional armor-clamp combinations for conductor protection, providing more advanced features for long-term reliability.
  • Line Angle Compatibility: The system is suitable for line angles between 30° and 60°. For angles above 30°, the Double Assembly is recommended for enhanced performance.
  • Conductor Compatibility: Advanced Suspension Clamp is compatible with a wide range of conductors, including ACSR, AAC, AAAC, compacted All-Aluminum, compacted ACSR, ACSS, and ACSS/TW conductors.

Material and Design

  • Housing Material:
     
    1. Galvanized Steel is used for cable diameters ranging from 0.272" to 0.500".
    2. High-Strength Aluminum Alloy Casting is used for conductor diameters from 0.482" to 2.233".
  • Elastomer Insert: A specially formulated elastomer insert resists ozone attack, weather conditions, and extreme temperatures. It also ensures durability by offering high resistance to compression set.
     
  • Rod Ends:
    • Ball Ends are used for non-EHV applications.
    • PARROT-BILL Rod Ends are available for Extra High Voltage (EHV) applications (345 kV and above), ensuring enhanced performance in high-voltage environments.

Temperature Specifications

  • Standard Version: It is designed to withstand continuous operation at temperatures up to 200°C, making it suitable for most transmission line environments.
  • High Temperature (HT) Version: The HT version is capable of withstanding conductor temperatures up to 250°C, providing extra durability in high-temperature applications.

Repair Applications

It can also be used to repair fatigue-damaged conductors. When applied over PREFORMED Armor Rods, it extends the lifespan of transmission lines, ensuring they remain functional even in the face of wear.

Safety Considerations

  • Single-Use Application: The product is designed for single-use but can be re-applied twice within 90 days for re-tensioning.
  • Installation by Qualified Personnel: Only qualified linesmen should install Power Line Suspension Grip to ensure safety and proper operation.

Extra High Voltage (EHV) Version

It is designed for use in high-voltage applications (345 kV and above), specifically featuring PARROT-BILL rod ends for superior stability and support.
