Product Description

Application

The TACSR (thermal resistant aluminum-alloy conductor steel reinforced) could withstand high tensile load to be used mainly for overhead transmission lines, overhead distribution wires.

TACSR (/AW) is used for overhead electric power transmission lines. Big city, seaside district, moisture area etc.

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 150oC 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.

Construction

Core(St, AW): Zinc-coated Steel Wire / Aluminum-clad Steel Wire(AW) : 14% ~ 40% AW

Conductor(TAI) : Thermal Resistant Aluminum HIGH TEMPERATURE CONDUCTOR Alloy Wire used for continuously allowable temperature up to 150oC.

The center wire or wires are of galvanized steel and the outer layer or layers of thermal-resistant aluminum-alloy. 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).

Characteristics

AW Type has excellent rustless characteristics.

Thermal-resistant Aluminum Alloy Conductors Steel Reinforced used in the 35KV 110KV 220KV 330KV 500KV 750KV 1000KV substation project, the wire alloying, improve high-temperature performance products, wire section, increase the carrying capacity, high temperature resistance, high conductivity, low loss, reduce power loss, improve the safety of equipment operation. Installation and maintenance are the same as ordinary Aluminum Conductors Steel Reinforced installation procedures, without any special tools, installation, installation, convenient maintenance and low cost.
