Problems solved by technology

The aluminum alloy core aluminum stranded wire adopts LHA1 or LHA2 type aluminum-magnesium-silicon alloy round wire stranded wire core as the strengthening core. Since the tensile strength of the aluminum-magnesium-silicon alloy round wire is 295MPa-325Mpam, it is required for the design of overhead lines , the cross-section of the reinforcing core needs to be very large, which increases the cost of materials and production and installation. The biggest disadvantage is that the ratio of tension to weight is reduced at the same time.
The all-aluminum alloy wire is directly stranded by HA1 or HA2 type aluminum-magnesium-silicon alloy round wire without a reinforcing core, but the maximum conductivity of the aluminum-magnesium-silicon alloy round wire is only 53% IACS, so the wire High energy consumption, uneconomical
