(VI) production equipment required for the present invention is design voluntarily all, and need not drop into new production equipment and production process and improve, processing ease, easy to maintenance, production efficiency is high, good product quality;

(VII) reasonable in design of the present invention, compact, soft, outward appearance is the characteristics of " skilful, little, blue or green, thin, soft ";

The pliability of (VIII) umbilical cable of the present invention is general as common colloid water pipe, and the space activity that good pliability has guaranteed the astronaut nimbly and freely;

Advanced insulating material, the protective materials of (IX) umbilical cable collection of the present invention, encapsulant are in one, and the application of combination redundant technique, have obtained remarkable result;

(X) umbilical cable of the present invention is a kind of extraordinary shielding soft type umbilical cable; It is for ensureing astronaut in the manned astro-engineering operate as normal and the space safety deliver from vault inside and outside in the airship cabin, returning " lifeline " when being referred to as astronaut's space deliver from vault again.

The present invention is fit to do space environment and uses cable, is particularly suitable for doing in the manned astro-engineering astronaut's space extravehicular activity and uses cable.

Below in conjunction with accompanying drawing and embodiment the present invention is done further explain.
