Aluminum stranded wire belongs to bare wire.

Aluminum clad steel stranded wire (LGJ) is commonly used as the conductor in China; Steel core mainly serves to increase strength, while aluminum stranded wire mainly serves to transmit electrical energy. The cross-sectional area of the wire varies depending on the voltage. For example, the conductors of domestic 630 kV transmission lines are generally LGJ-630/55 conductors. L is the abbreviation for aluminum wire, G is the abbreviation for steel core, J is the abbreviation for stranded wire, 400 is aluminum 400 square millimeters, and 35 is steel 35 square millimeters. Aluminum stranded wire and steel core aluminum stranded wire suitable for overhead power lines.
