Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

As described in the background art, the cable continuously releases heat to the surrounding environment during operation, and meanwhile, moisture and various harmful gases in the underground environment are slowly released into the space of the tunnel, so that the environment in the tunnel is severe.
