Join Dutco Tennant at the MEE Exhibition Stand Number H5, D10 in Dubai to explore the latest electrical technologies. We're excited to introduce the THERMOLIGN® Dead-end which is a useful solution designed to improve the reliability and performance of your transmission systems.

Discover how this innovative technology can help meet the growing demand for power and provide a better and more reliable way to terminate conductors. If you want to know more information, visit our MEE 2025 page.

As electricity demand is increasing day-by-day, having strong and dependable solutions is more important. Traditional dead-ends often struggle with extreme heat, tough weather, and mechanical stress, which can weaken power systems.

THERMOLIGN® Dead-end High-Temp Solution is designed to tackle these challenges, offering a better solution for high-temperature conductor terminations. 

Key Features of THERMOLIGN® Dead-end

1. Performance Matching:

It is designed to work seamlessly with ACSS, ACSS/TW, and ACCR conductors, ensuring efficient performance and optimal alignment with these conductor types for reliable power transmission.
2. Multi-Layer Design:

Its multi-layer construction enhances holding strength and improves heat dissipation. It provides superior support for the conductor and ensures long-term stability, even under high electrical loads or extreme environmental conditions.
3. Minimal Heat Transfer:

The design minimizes heat transfer to adjacent hardware and insulators, and helps to reduce the risk of damage to surrounding components and improve overall system efficiency by keeping temperatures in check.
4. Ease of Installation:

Unlike traditional dead-ends that require compression presses or dies, it simplifies the installation. It’s designed for easy setup, reducing both installation time and equipment costs.

5. Comprehensive Kit:

The complete kit includes Structural Reinforcing Rods, Dead-ends, a Thimble Clevis, and an Extension Link, offering everything needed for a hassle-free and secure installation.

THERMOLIGN Dead-end Benefits

  • High-temperature resistance, operating up to 250°C.
  • Vibration-resistant design to prevent mechanical failures.
  • Corrosion-resistant materials for long-lasting performance.
  • Compatible with modern HTLS conductors for efficient energy transfer.
  • It ensures mechanical and electrical reliability in power grids.
  • Tested for high mechanical and electrical reliability.

Applications of THERMOLIGN® Dead-end

  • High-temperature dead-end solution for enhanced reliability and strength.
  • Transmission systems to reduce conductor sag and improve stability.
  • Power lines to maintain electrical continuity for efficient transmission.
  • Harsh environments where resistance to thermal expansion, wind, ice, and corrosion is crucial.
  • Grid modernization projects to upgrade and increase efficiency and capacity.
  • Extreme weather conditions to prevent conductor damage and improve safety.
  • Long-term infrastructure for durability, minimizing maintenance and repairs.

The THERMOLIGN Dead-end has a practical application to the use of high-voltage transmission lines that are using HTLS conductors (example: ACSS (Aluminum Conductor Steel Supported) or ACCR (Aluminum Conductor Composite Reinforced)).

Modern power grids, with requirements for renewable energy integration or retrofitting of older infrastructure, could benefit greatly from this type of construction, so Wotton's work could prove quite impactful.

Utilization of THERMOLIGN® Dead-ends for the termination or anchoring of HTLS conductors has been designed for applications like the utility upgrading its transmission network to tie in renewable energy systems.

The dead-ends are designed to operate continuously at temperatures as high as 250°C, reliably surviving extreme thermal and mechanical stresses
