Introduction
High-Temperature Low-Sag (HTLS) HTLS conductor are pivotal in the modern power transmission landscape, offering enhanced performance under higher temperatures with minimal sag. This article will provide an in-depth look at various types of HTLS conductors, including ACSS, TACSR, GZTACSR, and Invar conductors. We’ll explore their current carrying capacities, specifications, manufacturers, prices, and applications in HTLS cables.
HTLS Conductor Full Form
HTLS stands for High-Temperature Low-Sag. These conductors are specifically designed to operate at elevated temperatures while exhibiting minimal sag, enabling them to carry more current efficiently. HTLS conductors are crucial for upgrading existing power lines to meet increasing energy demands and ensuring reliable power transmission.
Types of HTLS Conductors
ACSS (Aluminum Conductor Steel Supported)
ACSS conductors use a steel core to provide mechanical strength, while the outer layers of aluminum carry the electrical current. They are designed to operate at high temperatures with minimal sag.
Key Features:
- High temperature operation up to 250°C
- Reduced sag due to steel core
- High current carrying capacity
TACSR (Thermal Resistant Aluminum Alloy Conductor Steel Reinforced)
TACSR conductors incorporate thermal-resistant aluminum alloys, enhancing their performance in high-temperature environments. They are ideal for regions with high ambient temperatures.
Key Features:
- High temperature operation up to 210°C
- Thermal-resistant aluminum alloy
- Suitable for high-temperature regions
GZTACSR (Gap Type Thermal Resistant Aluminum Alloy Conductor Steel Reinforced)
GZTACSR conductors feature a gap between the aluminum layers and the steel core, allowing for thermal expansion and reducing sag. This design enhances their performance under varying thermal conditions.
Key Features:
- Gap design for thermal expansion
- High temperature operation up to 210°C
- Reduced sag and enhanced stability
Invar Conductor (High Strength Low Thermal Expansion Conductor)
Invar conductors use a special alloy core with low thermal expansion properties, making them ideal for minimizing sag in high-temperature applications.
Key Features:
- Low thermal expansion properties
- High mechanical strength
- Ideal for minimizing sag
Current Carrying Capacity of HTLS Conductors
The current carrying capacity of HTLS conductors is a critical factor in their selection and application. By operating at higher temperatures, HTLS conductors can carry more current compared to traditional conductors.
