1. Product Overview

High-Temperature Low-Sag (HTLS) Conductors are designed for overhead transmission applications requiring improved current-carrying capability and controlled sag at elevated operating temperatures. Compared with conventional ACSR conductors, suitable HTLS designs can offer higher operating-temperature capability, reduced thermal sag, and improved utilization of existing transmission corridors. Actual performance depends on conductor design, line conditions, fittings, and approved engineering calculations.

KJV Alloy Conductors Pvt. Ltd. presents HTLS conductor solutions using trapezoidal aluminium wires stranded around a hybrid carbon-and-glass-fibre composite core, as described in the source presentation.

2. Key Features

• High-temperature operation: the source presentation states operation up to 200°C. Confirm the applicable conductor design and rating before publishing this limit.
• Low sag at elevated temperatures, subject to design and installation conditions.
• Composite core construction using hybrid carbon and glass fibre.
• Trapezoidal aluminium wire construction for increased aluminium content in the stated designs.
• Potential for increased current-carrying capacity and reduced electrical losses compared with the referenced conventional conductor designs.
• Lightweight construction in the specific comparisons shown in the technical tables.

3. Construction

The construction described in the presentation comprises fully annealed, trapezoidal-shaped aluminium wires concentrically stranded over a hybrid carbon-and-glass-fibre composite core. The presentation identifies 1350-O tempered aluminium wires and a composite core.

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.

7. 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.
