1. Product application
The aluminum stranded wire is a bare wire, and the aluminum stranded wire mainly plays the role of transmitting electric energy. Depending on the voltage, the cross-sectional area of the conductor is also different.
| Model | Name | Conditions of Use | Remark |
| LJ | Aluminum stranded wire | It is used in general distribution lines with small force and small span | no contact with trees |
3. Product implementation standards
The aluminum stranded wire implements the GB/T1179-2017 "round wire concentric stranded overhead wire" standard

Main application
For high-voltage transmission lines, due to the limited path of the
line, it is impossible to erect multiple lines on one path. People
have come up with the idea of using one path, one set of iron
towers, and hanging multiple wires, that is, one line is equivalent
to erecting multiple lines. Line method; for 500KV transmission
lines, most of our country adopts the method of hanging four wires.
This method of wiring is called paralleling on the same tower
