"Xinchang is a new year, a new journey of dream building" - the 20th anniversary ceremony of Xinchang Copper Industry ended successfully

Aluminum alloy overhead stranded wire belongs to the original wire. China generally uses aluminum-clad steel strands (LGJ) as wires. The steel core mainly plays the role of improving the strength, and the aluminum stranded wire mainly plays the role of transmitting electricity. Depending on the voltage, the wire cross section varies. For example, the conductors of domestic 500kV transmission lines are generally LGJ-400/35 conductors. l is the abbreviation of aluminum wire, G is the abbreviation of steel core, J is the abbreviation of stranded wire, 400 is aluminum 400 square millimeters, 35 is steel 35 square millimeters.

In the aluminum alloy overhead stranded wire, any round aluminum wire is not allowed to join. The exception is the connector on the front of the finished cable mold. Connectors are permitted for round aluminum wires over 27 laps of aluminum stranded wire and steel core aluminum stranded wire.

Aluminum alloy overhead stranded wire is a commonly used item at present, but because the natural environment is often used outdoors, some anti-rust treatment is required, otherwise resources will be wasted due to corrosion. Needless to say, there may also be a hazard to the new project of the reaming line. When making steel strands, the aluminum alloy overhead strands are hot-dip galvanized during the process of making steel wires, which is also what we often use. Hot-dip galvanized steel wire can improve the quality of the data so that it can be reasonably guaranteed in a variety of natural environments.

The load-bearing core + conductor, also known as the reinforcement core, is to add a single-strand wire with higher strength in the center of the stranded wire to withstand the external tensile force, such as steel-cored aluminum stranded wire, aluminum alloy-cored aluminum stranded wire, and aluminum-clad steel-cored aluminum stranded wire. String.

Hundreds of feet to make progress and go further Henan Xinchang Copper Group "Aspects of Government and Enterprises" "was watched"

The Second President's Office Meeting of Henan Nonferrous Metals Association Copper Industry Branch in 2021 was successfully held

Thank you to everyone in Xinchang who worked hard to shine in the ordinary years. In the last 20 days of 2021, we will move forward hand in hand!

Walking into the high-end copper conductor project workshop of Xinchang Copper Industry with an annual output of 50,000 tons located in the industrial cluster area of ​​Gongyi City, the reporter saw that in the drawing area and stranding area of ​​the workshop, rows of fully automated intelligent equipment are running non-stop, outputting The coils of fine golden-yellow copper wire are particularly eye-catching.
