2. The utility model discloses be equipped with the one deck aluminium strip in the middle of the two-layer silica gel layer of protective sheath, because of the cold-resistant heat resistance nature that silica gel itself has, safer during the use can adapt to different application environment, adds the aluminium strip wherein and can prolong its life.

3. The utility model discloses still be equipped with anti-interference layer and shielding layer outside the insulating layer, can prevent external signal's interference, make cable transmission's signal can transmit under the condition that does not have the interference, and can avoid signal leakage among the data send process.

The present invention will be further explained with reference to the drawings and the embodiments.
