High Temperature Low Sag Conductor HTLS
High Temperature Low Sag Conductors (HTLS) are designed for high temperature environments and the need for efficient power transmission. VERI Cables produces these conductors to operate at higher temperatures than conventional conductors while maintaining a low sag, which significantly improves the performance and efficiency of transmission lines.
The main conductors of HTLS are as follows: TACSR, GTASCR, ZTACIR, ACSS, ACCC and ACCR, which are mainly composed of a mechanically strong steel core, an electrically conductive layer, and an anti-corrosion coating. To inquire about HTLS conductors, please contact us.

Environmental & Technical Advantages of HTLS Conductors
Environmental Advantages of HTLS Conductors
Reduced Carbon Emissions
HTLS conductors effectively reduce energy loss during transmission through high conductivity and low-sag design, especially suitable for long-distance transmission lines.
The increased transmission efficiency indirectly reduces the load demand of power plants and reduces greenhouse gas emissions.
Reduced Resource Waste
The high temperature and corrosion resistance of HTLS conductors significantly extends the service life of the line, reducing the waste of resources and secondary pollution of the environment caused by frequent replacement.
Reduced Land Use
HTLS conductor allows higher current to be carried in the line, avoiding the need to expand new transmission lines, thus reducing the occupation of land resources.
Use of Non-Hazardous Materials
Some HTLS conductors such as ACCC (Aluminum Composite Core Conductor) are made of carbon fiber composite materials, which are not only lightweight but also do not cause harmful pollution to the environment.
Reducing the Effects of Electromagnetic Radiation
Due to the more uniform electromagnetic field distribution of the conductor design, HTLS conductors produce lower electromagnetic radiation than conventional conductors during high load transmission, which has less impact on the surrounding environment and biology.
Technical Advantages of HTLS Conductors
Outstanding resistance to high temperatures
HTLS conductors can operate properly at temperatures up to 150°C to 250°C, whereas conventional conductors typically have a temperature limit of 90°C to 120°C. This high-temperature resistance allows HTLS conductors to remain stable under high loads or extreme climatic conditions.
Low Sag Design
The high temperature and low-sag characteristics are the core technical advantage of HTLS conductors, which are particularly suitable for transmission lines across complex terrain such as rivers, canyons and mountains.
High Transmission Capacity
HTLS conductors have 1.5 to 2 times the conductivity of conventional conductors, which can significantly increase the transmission capacity of the line without changing the existing transmission tower structure.
Lower Life Cycle Costs
While HTLS conductors may have a slightly higher initial cost, their high efficiency, long life, and low maintenance requirements significantly reduce whole life transmission costs.
