EPSILON CABLE Our mission: design and manufacture advanced conductors to modernize power lines worldwide Since 1987, Epsilon is a pioneer and world leader in high performance composite materials thanks to the pultrusion process. Epsilon Cable is at the forefront of the grid modernization, with a proven track record of several thousands of kilometers of advanced conductors installed worldwide in the past 2 decades. With its R&D center and Pultrusion facilities in France, Epsilon is ISO 9001 certified.

HVCRC ® Technology HVCRC® is a complete range of advanced conductors (also called High Capacity / High Temperature Low Sag or HTLS conductors) made of a strong lightweight composite core and trapezoidal aluminum strands. Compared with a traditional ACSR conductor, HVCRC® conductors allow to double the ampacity of a line or to decrease line losses by up to 30% while reducing sag. Several thousands of kilometers of HVCRC® conductors have been installed and energized successfully around the world since 2012, which makes it one of the leading new generation overhead high voltage conductors.

Epsilon manufactures composite core by pultrusion, using aerospace grade carbon fibers and a specific matrix to ensure the highest performance and durability. HVCRC® cores are qualified according to ASTM B987. They include an electrically insulating glass fiber layer to increase the core performance and flexibility, and protect the aluminum strands from galvanic corrosion. Epsilon works with the most demanding utilities and cable manufacturers to ambitious performance and cost targets.

HVCRC ® Accessories and installation HVCRC® conductors are installed using conventional compression accessories designed by Sicame, unlike some other HTLS solution, this reduces installation costs and complexity. As a result, the training of installation crews is simplified, and there is less risks of line failure due to improper installation. Different experts from Epsilon, Sicame or the stranding partners always support installation companies providing the up to date, current practices and guidelines to installation crews before and during installation.

Damping science mastering SICAME Group has vast experience on many overhead HTLS lines which have successfully been protected from vibration. SICAME has gained this experience, through advanced research projects including various partnerships with universities, scientific expertise using state of the art vibration simulation, damping techniques, and including various elastomer materials. SICAME expertise in R&D, design & test has and continues to assist Engineers, Consultants, and Utilities globally, with new types of spacer dampers or vibration dampers for all types of conductor configurations. SICAME Damping Systems Vibrations models induced by wind on single and bundled conductors which generate undesirable and dangerous phenomena on the OHTL: Aeolian Vibration (Vortex Shedding) Wake Induced Oscillation (Sub-Span Oscillation) Galloping

Sicame has developed the models which are linked to the tensile conductor loading and the particular evolution of self-damping linked to the use of the HTLS conductor.

Vibration level are controlled by Sicame using Damping Systems of Spacer Dampers and Vibration Dampers.

Spacer Dampers (SD) The range of SICAME SD covers all possible applications: Voltage up to 1.200kV Bundle Spacing up to 1.200mm Any conductor types Different clamping solutions

Vibration Dampers (VD) In order to satisfy the demands of the market, our range of VD is very wide. It includes models with galvanized steel or Zamac coated masses and models with galvanized steel or stainless-steel messenger cable.

Analytical Evaluation Damping Systems design An optimum Damping Systems is designed to evaluate the two vibration phenomena (Aeolian vibration and Sub-Conductor oscillation) on the OHTL, by means of a damping study, performed with validated software, issued by a collaboration with Politecnico di Milano. Due to thousands of hours of tests, we have acquired a good understanding of the dedicated self-damping profile linked to HTLS conductor and their different types.

Damping Systems validation The validation of a Damping System is carried out with measurements performed by SICAME equipment and personnel on the site ie (FIELD TEST). Such tests verify the real level of vibrations compared with evaluation at the design stage with the analytical method ie (DAMPING STUDY).

SICAME Transmission: Laboratories & Testing The Laboratory is vital in assisting both design activities and product verification. During the design stage, it supports the Technical Department in its activity of Research and Development while in the product verification stage all Quality Control mechanical verifications and tests are carried out to include batch acceptance tests.

A testing laboratory able to characterize and qualify HTLS conductors & accessories SICAME Transmission has state of the art resources among the best in the world which means that low sag / high ampacity conductors and accessories can be fine-tuned and qualified. The studies and trials are performed in accordance to the power, environmental, and configuration parameters of the line to be fitted. All tests comply with the requirements of the international reference standards or/and with the technical specifications of each country.

Compression fittings The compression fittings are co-developed and designed in collaboration with Epsilon Cable. Solution uses specific protective sleeve to protect the carbon core and brings high controlled crimping rate. The dedicated design allows a simple on-site installation, workers can use the same installation process and tools as a conventional ACSR conductor. Our connecting pads, aluminum sections, crimping length, and grease inhibitor are specifically designed to support the unique high transit capacity provided by HVCRC ® cable

Compression rate sizing For more than 20 years we have developed our knowledge related to the innovative technologies of composite cables. Based on this experience, we have fundamentally changed our designs of compressed fittings to adapt them to traditional crimping methods. We thus seek to guarantee perfect safety in the use of sleeves, by offering the possibility of using a technique proven on innovative products.

Our products respond perfectly to use in all circumstances and withstand without any problem accepting the highest transits associated with the use of these high temperature conductors throughout their life. The compression ratios have been defined to guarantee electrical continuity and ensure the mechanical resistance of the core, while optimizing the compression lengths, in order to obtain a compact, reliable and robust fitting, which are easy to install on site.

Suspension clamp and vibration damper Suspension clamps The armor grip design gives soft retention of the conductor without an inflection point, to avoid vibration fatigue, and stress on carbon core. Armor rod sets reduce the local temperature of a conductor by decreasing the joule effect and increasing the thermal dissipation. The lining of the suspension clamps have been specially designed and tested to guarantee the protection of the conductor in contact with the suspension clamp, by integrating the constraints of the external environment (UV, bad weather, etc.) associated with the high operating temperature requirements of the HVCRC® cable.
