- Important data check: the original slide repeats “Rated Strength of Core” on two consecutive rows, with the first row containing values that appear to correspond to conductor strength. The table above labels the first row “Rated conductor strength” based on the preceding slide’s row sequence; confirm against the approved datasheet before publishing.
- HTLS vs ACSR: General Comparison
| · Feature | · HTLS conductor (design-dependent) | · Conventional ACSR |
| · Core material | · May use a composite core such as carbon/glass fibre | · Steel core |
| · Thermal performance | · Designed for higher operating temperatures in applicable designs | · Typically more limited by conventional design and allowable temperature |
| · Sag at elevated temperature | · Can provide lower thermal sag for suitable designs | · Sag generally increases with conductor temperature |
| · Weight | · Can be lower in some comparable designs | · Depends on conductor size and steel content |
| · Current capacity | · Can be higher for a specified design and operating condition | · Depends on conductor design and allowable operating temperature |
| · Corrosion | · Composite core avoids steel-core corrosion; aluminium and fittings still require consideration | · Steel core may require corrosion protection and suitable handling |
| · Cost | · May have a higher initial conductor cost; evaluate lifecycle and reconductoring economics | · Often lower initial conductor cost |
| · Typical application | · Transmission capacity uprating and high-temperature overhead-line applications | · Conventional overhead transmission and distribution |
- Avoid absolute claims such as “highest conductivity” or “lowest sag in the HTLS category” unless supported by a defined benchmark, test data, and a specific conductor design.
