Applications
TACSR, Thermal-Resistant Aluminum alloy conductor,steel core reinforced is used for overhead transmission line, ground line, electric railway. Due to its obvious advantage of anti-corrosion and high strength, it is applicable for long- span line, severe cold zone with heavy snow and other bad weather besides general transmission line.Used for power plant, power transmission and distribution line, the voltage ranges from 1 kV to 750 kV, especially used in compacity – expansion route and transformation of the old lines.
Construction:
TACSR Conductors are very similar in construction to a conventional ACSR conductor but the EC Grade Aluminum wires are replaced with Hard Drawn Aluminum wires of Heat Resistant Aluminum Alloy (generally known as TAL ) . TACSR can be safely operated continuously above 150°C enabling to pump more current through the conductor. Where there is a need to transmit higher power but restrictions on getting new power corridors approved, various Types of TAL conductors are one of the best creative solution options to utilities. Ability of the Zirconium doped aluminum alloy to maintain its electrical and mechanical properties at elevated temperatures makes these conductors a very cost effective solution in refurbishing the existing lines with enhanced capacity.
Features:
1) Can carry 50%-60% more current than ACSR of the same size.
2) Higher capacity new lines can be built to deal with future demands.
3) Easy Installation, similar to conventional conductors.
4) No Special Hardware/Accessories
5) Better corrosion resistance than conventional ACSR due to Aluminum-clad steel (AS) core.
6) Losses Reduction in Transmission Line using LL-TACSR/AS Type Conductor.
7) Improve Conductor Drag Co-efficient advantage in Tower Tonnage.
