Super thermal-resistant aluminum-alloy conductors, Aluminum-clad invar 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.
Structure:
Application:
Overhead T&D lines-MV, HV & EHV (11 kV to 800 kV Lines).
Main Features
1. The current-carrying capacity of INVAR conductor in 210℃ is more than twice that of ACSR with same area in 90℃
2. The sag of INVAR conductor is kept in the same with that of ACSR with same overall diameter.
3. The aluminum-clad invar has good performance of resis- tance to electrochemical corrosion, and the working life of conductor can reach more than 40 years
Standard:
IEC 62004
