Recycling and Classification of Waste Cables

1. Recycling common electrical accessories: cable terminal junction box, waste wire and cable disposal method connection pipe and terminal, cable intermediate junction box, steel plate junction slot, cable bridge, etc.

2. Recycling Cable Bridge Frame: General industrial and mining enterprises lay power cables indoors and outdoors, disposal methods of waste cables and cables control cables also can be used for telecommunications, radio, and television departments' indoor and outdoor erection.

3. It can be divided into bare conductors, insulated wires, heat-resistant wires, power cables, control cables, shielded wires, communication cables, radio frequency cables, and so on.

4. Recycling cable intermediate joints: devices that connect cable to cable, insulation shielding layer, and the protective layer, so as to connect cable lines. 

The disposal method of waste wire and cable is called cable intermediate joints.

Treatment of Waste Cables

1. Manual peeling method: This method uses manual peeling, which has low efficiency, high cost, and poor operating environment for workers.

2. Incineration method: The incineration method is a traditional method, which burns the plastic skin of waste cables and recovers copper, but the smoke pollution is very serious. 

At the same time, the surface of copper wires is seriously oxidized during the incineration process, which reduces the metal recovery rate. 

This method has been strictly prohibited by governments all over the world.

3. Mechanical peeling method: using a cable peeling machine to deal with the waste wires and cables. 

This method still needs a manual operation. It is semi-mechanized, labor-intensive, inefficient, and only suitable for the treatment of thick cables.

4. Chemical method: The technology of dealing with waste wires and cables by the chemical method was put forward in the 1990s. 

Some countries have studied the methods of dealing with waste wires and cables, and our country has also studied them during the Eighth Five-Year Plan. 

The biggest disadvantage of this method is that the waste liquor can not be disposed of and has a great impact on the environment, so it is seldom used.

5. Freezing method: The method of disposing of waste wires and cables was also put forward in the 1990s. 

Liquid nitrogen was used as a refrigerant to make waste wires and cables brittle at extremely low temperatures and then broken and vibrated to separate plastic sheets from copper segments. 

During the Eighth Five-Year Plan period, a study was carried out in China. 

The method of disposing of waste wires and cables was also put forward. However, the disadvantage of this method is its high cost and difficulty of entry.
