Conducteur Invar – Fabricant du conducteur HTLS

Introduction to Invar Conductor

Invar Conductor is a specialized type of Conducteur HTLS (Faible affaissement à haute température) designed to improve efficiency in power transmission networks. Due to its unique composition, it offers reduced thermal expansion and enhanced mechanical properties, making it a preferred choice for high-voltage transmission lines. Deux câbles is a global manufacturer and supplier of Conducteur Invar, providing high-quality solutions for modern electrical infrastructure.

What is Invar Conductor?

Invar Conductor is composed of an Invar core, a nickel-iron alloy known for its extremely low thermal expansion coefficient. This core is surrounded by high-conductivity aluminum strands to ensure optimal electrical performance. The combination of materials allows the conductor to operate efficiently under high temperatures while minimizing sag, which is crucial for overhead power lines.

Key Benefits of Invar Conductor

1. Faible extension thermique: Unlike traditional conductors, Invar exhibits minimal expansion at high temperatures, reducing sagging issues.
2. Enhanced Mechanical Strength: The Invar core provides superior tensile strength, making it highly durable for extreme environmental conditions.
3. High Current Carrying Capacity: With its aluminum outer layer, Invar maintains excellent conductivity, ensuring efficient power transmission.
4. Reduced Transmission Losses: The optimized material composition results in lower electrical losses compared to conventional conductors.
5. Longer Lifespan: Its resistance to thermal fatigue and environmental factors extends the service life of power lines.

Invar Conductor Specifications

The specifications of Invar Conductors are based on application requirements. Cependant, common Invar Conductors specifications include:

• Matériau de base: Invar alloy (Nickel-Iron composition)
• Outer Layer: Aluminum or Aluminum-Zirconium strands
• Température de fonctionnement: Typically up to 210°C
• Thermal Expansion Coefficient: ~1.2 x 10^-6/°C (significantly lower than standard conductors)
• Tensile Strength: Higher than conventional ACSR conductors
• Capacité de charge actuelle: Increased capacity due to HTLS properties
• Performances d'affaissement: Reduced sag compared to standard ACSR conductors
• Résistance à la corrosion: Enhanced protection against environmental conditions

Applications of Invar Conductor

1. High-Voltage Transmission Lines: Used in long-distance transmission networks to minimize power losses.
2. Urban Power Grids: Ideal for congested city areas where minimizing sag is crucial.
3. Projets d'énergie renouvelable: Essential for integrating wind and solar power into the grid.
4. Upgrading Existing Lines: Invar Conductors allow for capacity upgrades without requiring additional infrastructure.
