Aluminum conductor steel reinforced manufacture. Aluminum conductor steel reinforced is "LGJ"for short, which is made of aluminum and steel strand, and ordinary aluminum strand "LJ" is mainly used in aerial transmission cables. The internal of the aluminum conductor steel reinforced is the steel "core", and the external is to twist the aluminum wire around the steel core; The steel core is mainly to increase the strength, and the aluminum strand is mainly to play the role of power transmission. Both belong to the bare wire from the manufacturers of aluminum conductor steel reinforced, which is basically the same in the use, and different in the way to indicate the model specifications.

Ordinary aluminum strand: the model is represented by with "L J", which belongs to the bare wire. At present, China generally uses aluminum conductor steel reinforced(LGJ) as a wire, steel core mainly plays the role of increasing the strength and the aluminum strand is mainly to transmit electricity. Depending on the voltage, the cross-sectional area of the wire is also different. For example: the current conductor in the 500 kV transmission cable, it generally uses the LGJ-400/35 wire. Where L is short for aluminum, G is short for steel core, J is short for stranded wire, 400 is 400 square millimeters of aluminum, 35 is 35 square millimeters of steel.

[Model meaning]: For example, GB1179-83 "aluminum strand" nominal cross-section: 240 square millimeters of aluminum strand.

Specification model can be expressed as: LJ-240GB1179-83

GB1179-83 nominal cross-section: the "aluminum conductor steel reinforced" with 300 square millimeters of aluminum, 50 square millimeters of steel .
