In the cable, copper aluminum cable is a more common one. However, the service life of copper-aluminum cables is limited, and once the service life is up, it will be abandoned. At this time, the recycling of copper and aluminum cables is particularly important. First of all, the recycling of copper and aluminum cables is crucial to environmental protection. 

Discarded copper and aluminum cables often contain a variety of harmful substances, such as lead, cadmium and other heavy metals. These substances, if discarded at will, will cause serious pollution to the environment, damage the ecological balance, and threaten human health. Therefore, recycling of discarded copper and aluminum cables can effectively reduce environmental pollution, protect the ecological environment, and reduce the threat to human health.

Secondly, the recycling of copper-aluminum cables is also of great significance for resource conservation. Copper and aluminum are important non-ferrous metals with high economic value.

Recycling discarded copper and aluminum cables can extract useful metals from them and be reused, thereby reducing the consumption of natural resources.
