High Temperature Thermal Resistant Alloy conductors TACIR and ZTACIR

Product Description

Definition

Super thermal-resistant aluminum-alloy conductors, Aluminum-clad invar conductor reinforced

INVAR conductor is composed of aluminum clad invar core and thermal-resistant aluminum alloy wires. This conductor is suitable for old line modification. It can keep the same sag while increasing capacity.

Standard

• IEC 62004
• IEC 61089
• JCS 1404
• Q/320623 AP 25

Structure

Technical characteristics

• The current-carrying capacity of INVAR conductor in 210℃ is more than twice that of ACSR with same area in 90℃.
• The sag of INVAR conductor is kept in the same with that of ACSR with same overall diameter.
• The aluminum-clad invar has good performance of resistance to electrochemical corrosion, and the working life of

conductor can reach more than 40 years.
