Answer: As a leading manufacturer and exporter in the power industry, we at Ningbo Changshi understand the critical need for efficient and reliable power transmission. A High-Temperature Low-Sag (HTLS) conductor is an advanced type of overhead power line cable designed to operate at much higher temperatures than conventional conductors, while exhibiting significantly less thermal sag. This is achieved by using specialized materials like advanced aluminum alloys or composite cores, which have a lower coefficient of thermal expansion. The key benefit of HTLS conductors is that they can carry more electrical current without excessive sagging, allowing utilities to increase the capacity of existing transmission lines without building new towers.
