Characteristics
● The current-carrying capacity of INVAR conductor in210℃ is more than twice that of ACSR with same area in90℃.
● The sag of INVAR conductor is kept in the same with thatof ACSR with same overall diameter.
● The aluminum-clad invar has good performance of resis tance toelectrochemical corrosion, and the working life ofconductor can reach more than 40 years.
