Tacsr Power Conductor Thermal Resistant Aluminum Alloy Conductors Steel Reinforced

TACSR

 New aluminium alloy having high thermal resistance can with stand heat upto 150°C without significant lossin strength throughout its life time. This conductor is similar to an ACSR conductor. Only the conductive layer is replaced with Thermal alloy to avoid the hard drawn aluminium’s loss of strength at 150°C

TACSR has 1.6 times higher ampacity than a similarly sized ACSR conductor
 No need for modification or reinforced required for the towers
 Steel core either aluminium clad or galvanized (After knee point Linear coefficient is 11.5 X 10-6/°C)

Application :

TACSR is used to up-rate the existing transmission line (X 1.6) by simply replacing the existing theconductor without tower modification.

Standard :

IEC, ASTM and Gupta Power Specification.

Construction of the conductor :

Outer Conductive wire : Thermal aluminium alloy wire which can continuously operate up to 150°C.

Inner Core wire : Aluminium Clad/Galvanized steel wire.
Thermal Aluminium Alloy

The thermal resistance of aluminium can be improved by adding Zirconium so as to keep the strength even athigh temperature. The thermal resistance alloy can operate up to 150°C with specified strength loss.
The Super thermal resistance alloy has similar mechanical and electrical properties like EC 1350.

Core Wire :
The Aluminium Clad / Galvanized steel wire is similar to an ACSR conductor. Aluminium clad steel minimizesthe power loss.
Advantage 

For Uprating Lines : 

• 1.6 times higher Ampacity than ACSR
   
• No modification/Reinforcement of Towers
   
• Cost effective

For New Lines : 

• Lesser Tower height
   
• Number of Towers can be minimized
