Technical Parameters

Hebei Hualun Cable Co., Ltd. is one of the most reliable manufacturers and suppliers of tacsr conductor in China. If you're going to wholesale durable tacsr conductor made in China, welcome to get quotation from our factory. All customized products are with high quality and competitive price.

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

Product Q&A

Q: What is the difference between the heat-resistant aluminum alloy wire of TACSR Conductor and ordinary aluminum wire in crimping?

A: The hardness of the heat-resistant aluminum alloy wire differs from ordinary aluminum wire. Aluminum crimp sleeves and dies matched to TAL conductors should be selected during crimping, and the crimping parameters for ordinary ACSR should not be directly applied. Remove the surface oxide film before crimping, and check the joint for cracked wires or flash after crimping.

Q: What is the allowable short-term temperature of this conductor during operation?

A: This conductor can be safely operated continuously above 150°C. The temperature under short-term overload or short-circuit conditions is determined by the line design. During operation, long-term exceeding of the conductor's allowable continuous operating temperature should be avoided.

Q: When this conductor is used for capacity upgrading of an existing line, does the sag need to be adjusted after replacing the conductor?

A: Yes. The weight and mechanical characteristics of TACSR may differ from the original ACSR, so the sag should be rechecked according to the design tension after replacement. When enhancing line capacity where additional power corridors are not feasible, confirm whether the towers and insulators meet the tension and sag requirements of the new conductor.
