We are qualified by most leading cable manufacturers that supports like ACSS, invar, gap, carbon core and metallic matrix type

Since 2001, Sicame Group has been working closely with the French electricity grid (RTE: Réseaux de Transport d’Electricité) and other major utilities, to successfully qualify HTLS conductor sets and accessories. Dervaux, a Sicame Group's subsidiary, has confirmed now, its strong technical capacity to design line hardware suitable to the HTLS conductors characteristics requirements:

  • Maximum operating temperature (up to 250°C)

  • Fully annealed aluminium for conductor strands

  • Gauges according to the required outputs

We are qualified by most part of cable manufacturers either type of HTLS conductors, ACSS, invar, gap, carbon core and metallic matrix type. These specific conductor characteristics require the study and qualification of line hardware that results in safe, durable installations, whether new or existing lines. This design results in good conductivity, good mechanical characteristics, and a low conductor sag.

Suspension clamps

Armor grip design ensures gentle conductor retention, preventing vibration fatigue and carbon core stress. Armor rods decrease local temperature and enhance thermal dissipation. Specially lined suspension clamps protect conductors from environmental factors and meet HTLS cable temperature demands.

Mid-span joint

HTLS expertise yields a midspan joint, compliant with IEC 61284, shorter than competitors for quicker on-site crimping.

 

 

 

 

 

Deadend

Deadend and terminal connector pads, compliant with IEC 61284, feature a 15º angle, enabling bolt-on in straight or 30º position.

 

 

 

 

Helical

Armor rods protect conductors at suspension points and stockbridge vibration dampers, reducing strains and extending conductor life in harsh conditions.

Jumper terminal

Sicame jumper terminals: Reliable, corrosion-resistant connectors for overhead transmission lines. Easy installation, high safety standards.

Sicame repair sleeves: Durable connectors for repairing overhead transmission lines. High-quality materials, easy installation.

Testing laboratory

A testing laboratory able to characterize and qualify

HTLS conductors and accessories

We have test resources among the best, which means that low sag / high ampacity conductors and accessories can be fine-tuned and qualified. These studies and trials are performed according to the power, environmental, and configuration parameters of the line to be fitted. The tests comply with the requirements of standard IEC 61284.

Tests compliant with the specifications of each country can be performed by the Sicame Group transmission laboratories.
