In the face of global resource exhaustion and environmental deterioration, environmental protection, saving and consumption reduction become the subjects of cable industry development, and cable product environmental protection is a development strategy of long-term sustainability in enterprises in the future and is also a necessary and competitive hot spot for the enterprises to live on. The development concept is contrary to the concept of building a conservation-oriented society and developing a circular economy proposed by the state, and has strong vitality under the background that the resources of the everyone in China are deficient and the economic growth mode is changed from a rough type to an intensive type.

The loss of the cable transmission power, besides the conductive core loss (WC = I2 × R), also the insulating medium loss and the metal and armor loss amounts (λ 1, λ 3); the alternating current resistance of the conductor is related to the conducting performance of the material, the skin effect and the proximity effect, and is also greatly related to the operating temperature of the conductor, when load current passes through the resistance of the conductor, heat is generated, so that the temperature of the conductor is increased, and the actual resistance of the conductor is changed along with the change of the environmental temperature and the load current.

The temperature of the cable is increased along with the increase of the load when the operation time is prolonged, the loss of electric energy is also increased, the aging of the insulating material is also intensified, and the service life is shortened; if the operating temperature of the cable can be reduced, namely the resistance of the cable conductor is reduced, the loss of electric energy is reduced, meanwhile, the aging of the insulating material is slowed down, and the service life of the cable is prolonged.

The present invention has been made in view of this situation.
