Condutor HTLS
Condutor HTLS (Alta temperatura baixa-sag) are advanced overhead transmission conductors designed to operate at higher temperatures low sag.
HTLS Conductor have Condutor ACCC, Condutor Invar, Condutor ACSS, GTACSR Conductor, Driver TACSR, Driver Ztacir, ACFR Conductor and ect..
Compared to traditional conductors like ACSR (Condutor de alumínio reforçado com aço), HTLS conductor significantly enhance power transmission capacity without requiring major structural modifications to existing power lines.
Features:
- High-Temperature Resistance
- Low Sag
- Increased Current Capacity
- Improved Mechanical Strength
HTLS Conductor types

Condutor ACCC
ACCC conductor features a composite carbon or glass fiber core instead of steel, making it one of the most advanced HTLS conductors. Advantages include: Ultra-lightweight yet high-strength composite core.
Reduced sag and higher efficiency compared to conventional conductors.
Increased power transmission capability with lower line losses.
Resistance to extreme weather conditions.

Condutor Invar
Invar conductor is a high-performance HTLS conductor featuring a core made from an iron-nickel alloy (Invar) with a low thermal expansion coefficient.
- Baixa expansão térmica: Maintains stability at high temperatures with minimal sag.
- High-Temperature Resistance: Operates efficiently at temperatures up to 250°C.
- Increased Transmission Capacity: Enhances power transfer while reducing line losses.

Condutor ACSS
ACSS conductor is a popular HTLS conductor that uses fully annealed aluminum strands around a steel core. The key advantages of ACSS include:
High-temperature endurance up to 250°C.
Minimal sag due to the steel core support.
Excellent self-damping properties, reducing vibration-induced damage.
Enhanced corrosion resistance for longer service life.

GTACSR Conductor (Gap-Type Aluminum Conductor Steel Reinforced)
GTACSR conductor consists of a steel core surrounded by a gap filled with grease, which separates the steel and aluminum strands. This structure allows:
Higher mechanical strength and reduced sag.
Operating temperatures of up to 250°C.
Enhanced thermal expansion control, improving performance over long spans.

Driver TACSR (Thermal Resistant Aluminum Conductor Steel Reinforced)
TACSR conductor is an improved version of the traditional ACSR (Condutor de alumínio reforçado com aço) but with thermal-resistant aluminum alloy strands. Benefits include:
Higher current-carrying capacity compared to ACSR.
Ability to operate at temperatures up to 150°C.
Reduced sag and longer operational lifespan.

ACFR Conductor (Aluminum Conductor Fiber Reinforced)
ACFR conductor utilizes a fiber-reinforced composite core for superior mechanical and electrical properties:
High-temperature tolerance exceeding 200°C.
Excellent corrosion and fatigue resistance.
Significantly lower sag and increased power transmission efficiency.
HTLS Conductor Advantages

Alta temperatura baixa-sag (HTML) conductors provide significant advantages over traditional transmission conductors, making them an essential solution for modern power grids. Below are the key benefits of HTLS conductors:
1. Higher Ampacity
HTLS conductors can operate at elevated temperatures (up to 250°C or higher), allowing for increased current-carrying capacity without compromising safety or efficiency. This makes them ideal for power grid upgrades and capacity expansion.
2. Reduced Sagging
Unlike conventional conductors, HTLS conductors have a lower thermal expansion coefficient, which minimizes sag even under high loads. This ensures better ground clearance and improved reliability, particularly in long-span transmission lines.
3. Enhanced Energy Efficiency
HTLS conductors exhibit lower electrical resistance, reducing power losses during transmission. This results in improved overall energy efficiency, lower operational costs, and enhanced grid performance.
4. Cost-Effective Grid Upgrades
Utilities can replace existing conductors with HTLS conductors without modifying towers or structures, significantly reducing infrastructure costs. This enables efficient capacity expansion without extensive investments.
5. Superior Durability and Longevity
Designed to withstand extreme weather conditions, HTLS conductors resist corrosion, fatigue, and mechanical stress, leading to a longer service life and reduced maintenance requirements.
By integrating HTLS conductors into transmission networks, utilities can improve efficiency, confiabilidade, and sustainability while minimizing costs and environmental impact.
