KTACSR/KTACSR-AW Thermal-Resistant Conductor
KTACSR conductor uses high-strength thermal-resistant aluminium-alloy outer wires, identified as AT2 in the available catalogue, around a steel reinforcing core. KTACSR-AW changes the core to aluminium-clad steel. The product is selected when thermal duty and outer-wire strength must be considered together rather than treating all TAL conductors as equivalent.
Key Advantages
- High-strength thermal alloy: AT2 outer wires address both temperature and mechanical requirements.
- Two core systems: Coated steel and aluminium-clad steel options can be assessed separately.
- Suitable for demanding spans: Strength class and conductor geometry are selected from dedicated tables.
Product Overview
KTACSR is distinguished from general TACSR by the specified high-strength thermal-resistant aluminium-alloy system and its own rated-strength constructions. The outer wires remain the principal current-carrying section, while the core provides reinforcement. Round-wire KTACSR should also be kept separate from any KTACSR/TW shaped-wire variant.
The AT2 designation alone is not sufficient for procurement. The approved data sheet must identify wire properties, core type, conductor strength class, stranding, diameter, mass, resistance and temperature assumptions. Mechanical and thermal studies must then confirm spans, clearances, fittings and operating duty.
Key Features
- High-strength thermal-resistant aluminium-alloy wires form the conductive outer layers.
- KTACSR and KTACSR-AW use different core surface systems and require separate construction data.
- Dedicated strength classes support selection for crossings and other high mechanical duties.
- Round-wire geometry, core grade and thermal assumptions must remain traceable through design, supply and installation.
Product Applications
- High-capacity overhead lines requiring stronger thermal-resistant outer wires
- Long spans or crossings where both conductor strength and thermal duty are critical
- Reconductoring studies comparing coated-steel and aluminium-clad steel core systems

From Production to Delivery
From raw material preparation to final shipmen, every stage is caretuly controled to ensure consistent conductor quality, reliable pertormance,and sae delivery. Our roduction,
inspection, packaging, and logistics processes are managed in accordance with applicable standards and project requirements.
Production
Type AT2 alloy wire is produced to the specified strength and conductivity condition, then stranded around the approved galvanised or aluminium-clad steel core.
Inspection
Inspection verifies alloy designation, wire dimensions, core material, strand arrangement, strength class, finished diameter and catalogue values.
Packaging
Packaging controls winding tension and surface protection so the high-strength alloy layers and selected core are not displaced or damaged.
Shipping
Shipment records identify KTACSR or KTACSR-AW, core class, conductor size, drum length and the approved inspection documentation.
Frequently Asked Questions
What makes KTACSR different from standard TACSR?
KTACSR uses a specifically identified high-strength thermal-resistant alloy system and dedicated strength classes. Its construction table and approved wire properties must be used rather than substituting a general TACSR design.
When is the KTACSR-AW core variant relevant?
It is relevant when the project specifies aluminium-clad steel reinforcement or needs to compare that core surface system with the coated-steel KTACSR option. The complete core grade must still be stated.
Does AT2 identify a finished conductor temperature rating by itself?
No. It identifies the wire material system used in the catalogue. Finished-conductor temperature limits require approved material data plus checks of core, grease, connectors, clamps, clearances and operating policy.
Can KTACSR be selected for a crossing from tensile strength alone?
No. Crossing design also considers conductor mass and diameter, wind and ice loads, sag, creep, vibration, support loads, clearances, fittings and construction conditions.
Why should KTACSR/TW data not be mixed with round-wire KTACSR?
Shaped-wire geometry changes the aluminium packing, finished diameter, contact surfaces and fittings. A TW construction needs its own table and hardware review even when the alloy and core family are related.
What should a KTACSR technical offer clearly identify?
It should identify the alloy and condition, core system and grade, strength class, construction values, thermal assumptions, tests, sag-tension data, fitting compatibility, drum schedule and installation requirements.
