[0026] When in use, the silicone rubber cable is provided with a glass fiber wrapping layer 1 that is resistant to weathering and high temperature.

When the cable is subjected to mechanical crushing during use, the buffering effect of the inner wire body 8 is improved, and the damage to the bundled wire core 9 in the inner wire body 8 is reduced.
