The outside of inhaling ripple layer 3 is coated with a thermal insulation layer 5, and thermal insulation layer 5 forms by silastic material is coated. Utilize the heat resistance of silicon rubber excellence, set it as thermal insulation layer 5 materials'uses, do not cause the inside heat production of cable more to pass to oversheath 2, the heat that cable core 1 can be produced because working long hours is as far as possible isolated with thermal insulation layer 5, the oversheath 2 of protection cable.

Oversheath 2 is to adopt the complete poly-fluorine ester plastics of insulation to make, and has good insulating properties, and cable is played to protection effect.

Designing like this according to insulating barrier 4, suction ripple layer 3, thermal insulation layer 5 from inside to outside, is because first need an insulating barrier 4 by coated cable core 1 in the outside of cable core 1, makes its globality better, and insulating barrier 4 plays the effect of security protection simultaneously; Secondly be coated with and inhale ripple layer 3 at insulating barrier 4 outer surfaces; instead of be coated with thermal insulation layer 5 in its outside; to be very thin one deck because inhale ripple layer 3; if be coated in thermal insulation layer 5 outer surfaces from oversheath 2 very close to; if damaged can directly damage of oversheath 2 inhaled ripple layer 3; the important absorption of electromagnetic radiation structures of this cable and inhale ripple layer 3, therefore will carefully protect.

The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model. It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
