Introduction to ZTACIR Conductor
ZTACIR (Leiter aus Zirkonium-Wärmelegierung mit Invar-Verstärkung) ist ein Hochtemperatur-Low-Sag (Htls) Leiter, der für moderne Energieübertragungsanforderungen entwickelt wurde. Es bietet eine hervorragende thermische Beständigkeit, lower sag characteristics, and increased current carrying capacity compared to traditional conductors such as ACSR (Aluminiumleiter stahlverstärkt) or AAAC (Leiter komplett aus Aluminiumlegierung).
As a leading ZTACIR conductor manufacturer, we provide high-performance conductors tailored to the demands of modern power grid infrastructure. Our ZTACIR conductors are engineered to optimize efficiency and reduce transmission losses, making them an ideal choice for upgrading existing lines and deploying new high-capacity power transmission networks.

Advantages of ZTACIR Conductor
- High-Temperature Performance: Operates at temperatures up to 210°C without compromising mechanical integrity.
- Low Sag Characteristics: Incorporates an invar (Fe-Ni alloy) reinforced core to minimize thermal expansion, reducing sagging at high temperatures.
- Enhanced Current Carrying Capacity: Supports higher ampacity compared to conventional conductors, allowing efficient power transmission.
- Korrosionsbeständigkeit: Zirconium-enriched aluminum alloy enhances oxidation and corrosion resistance, increasing the conductor’s lifespan.
- Lightweight yet High Strength: A combination of lightweight aluminum alloy and invar core provides excellent strength-to-weight ratio.
- Vorteile für die Umwelt: Reduced transmission losses contribute to a lower carbon footprint and increased energy efficiency.

Applications of ZTACIR Conductors
ZTACIR conductors are widely used in modern transmission infrastructure due to their superior efficiency and reliability. Below are some of their key applications:
1. High-Voltage Power Transmission Lines
ZTACIR conductors are ideal for high-voltage (Hv) und extra-hohe Spannung (EHV) Übertragungsleitungen, offering reduced sag and enhanced current carrying capacity.
2. Upgrading Existing Power Lines
Replacing ACSR conductors with ZTACIR conductors allows utilities to increase power transmission capacity without changing tower structures. This is a cost-effective way to modernize power grids without extensive infrastructure modifications.
3. Renewable Energy Integration
ZTACIR conductors are essential for integrating solar and wind energy into power grids. Their high ampacity allows them to transmit large amounts of energy over long distances with minimal losses.
4. Urban Power Transmission
In densely populated areas where transmission corridors are limited, ZTACIR conductors help utilities maximize power transmission within existing rights-of-way.
5. Overhead Transmission in Harsh Environments
Due to their corrosion-resistant properties, ZTACIR conductors are well-suited for coastal regions, industrial zones, and areas with extreme weather conditions.
6. Industrial Power Distribution
Heavy industries such as mining, steel production, and chemical plants require high-capacity power transmission, making ZTACIR conductors a reliable solution for these applications.
