Application
The product is used in areas with bad weather conditions. It can be used in corrosive aeras like coastal areas industrial zones. This ACSR is filled with anti-corrosion grease applied on the gaps between stranded wires and their external surfaces.
Construction
Bare conductors with grease
Values of k are given in the following table for four cases of grease application, a grease density of 0.87 g/cm3, and a minimum fill factor of 0.70:
Case 1: Steel core only greased.
Case 2: All the conductor is greased except the outer layer.
Case 3: All the conductor is greased including the outer layer.
Case 4: All the conductor is greased except the outer surface of the wires in the outer layer.
