The short and vertical range of oversheath outside wall surface is 0.5-1cm.
Further：The outside wall surface of described inner liner is provided with nickel coating.
The utility model compared with prior art, has advantages below and effect：The utility model is reasonable in design, work(
The armor of energy overcoat has the crushing resistance for strengthening cable, and described waterproof layer obstructs to outside infiltration, fire prevention deoxidation
Layer and refractory filler ensure that fireproofing of cable performance, and described inner liner is provided with nickel coating, ensure that cable has
Good decay resistance, the centrally disposed elastic supporting member for supporting optical member of cable core of described cable not only cause have in cable is processed
It is fixed well, while prevent in cable laying due to the elastic buffer of center resilient support part, prevent cable core from pullling
Fall drawing in break, the rigid projection spiral winding of oversheath of the present utility model has rigid rope, lay earth's surface or it is buried when, have
The destruction for causing cable of gnawing for preventing other animals such as muroid in nature of effect, while when buried, described rigid projection
The contact area with soil property is added when buried, while ensure that good earth-grasping force, is also effectively increased radiating
Area, it ensure that cable has good thermal diffusivity.
